Tom forwarded these pictures for me to post. Some of them are kind of blurry, but you get the general drift of what's going on. I like the Holman Moody dyno data, and what looks like some kind of a magneto, plus the SOHC stuff. Tom has promised to come on and give a description of what we're looking at here...

Hope his posts don't turn into an argument like on the FE forum. Why would there be fuzzy pictures of parts and clear picture of magazine article in notebook? Sounds fishy to some of us who have been following his posts. Sorry, Jay, but I am not impressed until we find out who he really is, and his credentials. I would hate for controversy to come to your forum like some of the posts on Network 54. Joe-JDC

We'll make sure that doesn't happen here, Joe ;) I think the pics are kind of cool, myself, with the old SOHC blower manifold and the Holman Moody dyno data. Those SOHC cams say Crane Nitro 660 right on them, which is also kind of cool. That stuff is all FE related, and I've never seen most of it before...
-
I think the pics are cool regardless of who they're from. I just want more and better ones! :D

Very cool to see stuff like that!

Here's a few more that Tom sent me. The first two are of an FE girdle that Tom says is from back in the day. This one is interesting because the main caps do not bolt through the girdle, so maybe no special machining is required on the block? Very interesting, and I wonder how well it could work as compared to a girdle with the caps bolted through. Also some 428CJ Holman Moody dyno data, from January 2, 1969, and a few other shots:

I think that girdle was made solely for the fuel dragster/funny car crowd. Tom would know.

Wonder how long the sweeps were on that 428 dyno? I've never seen an engine pickup 20 degrees of oil temp unless it was hurt....

Thanks a lot Jay for all that you do and for all that you have done.
The first comment is to Joe C. Dear Joe, I recall when a few mean guys really gave you grief on 54 and I was one of many who stood up for you. We exchanged pleasant emails too and I offered to send you work, etc. You were moving and I enjoyed the exchange. You resigned from 54 and I was one of many who missed your brains. I rarely see you there now and have enjoyed seeing your thinking here. There is a point in many professionals career where they have to limit the time that a few very mean and wrong people can demand of you by cyber bashing, fabrications, off topic lies, and so on.
Here is what changed my mind. The people at 54 deleted posts by several mean guys, offered to block a few, and thanked me sincerely for our work there. In fact, a kind nice man said he has it in a book or keeps it filed. But I am told some level of fighting and arguing and so on is fine and that is no way to recall the old Ford Race teams we were with. I will still try to add content, but when some supposed expert claims the old shop, that won and won for FORD and MERC, caused a horrible death, despite the same set up winning the USAC Championship that year, that is nuts. I will be there very rarely for a while. The Administrater himself apologized for the cyber trolling, and suggested I work here.
When you say 'our' Forum, that is real nice. I have tried to post here as time allows, on and off, about 2 years. Jay and I exchange email and he is the class of the field. All it took was having bashers steal 2 days from me to argue nonsense there to figure out that the fighting is just for their entertainment or whatever. Jay and I talked, he shed wonderful light on these problems, to say thank, here is some rare FORD data.
I had a change of mind while this slander campaign unfolded by coming here to just think engines. I log on here and ,ahhhhhhhhhh,,, Engineering, builds, tune ups, power, racing, designs, smart guys, nice guys, fun guys. This is much more like our past teams. A group of real good guys, combining experience, to do well and win.
I have hundreds of emails from 54 members who never posted and agree with the above. They also usually ask me to please not stop posting due to 2 or 3 mean guys. For now, I will try to add a little here as time allows. I value every builder here, and believe the old Ford guys are all great. I am no better or worse than any car guy, I look up to so many, and down toward none.
Thanks for all you do Joe. I removed the Vet deal for you since I re registered and wish you the best. Recall Joe, I sent you the highest praise I had once, said you reminded me of Warren Brownfield a bit. He invented the flow bench and did the forst ones at Edelbrock. He did Dyno Don's best SOHC heads too
We are fine, my guys are so thankful, we laugh, race and try. Thanks for the note.
-
I will add that I've met and talked to Tom in person and he was nice enough to introduce me to Stroppe Jr. We've talked and emailed on several occasions and he's always been very helpful.
-
On the pictures. Thanks so much Jay for uploading them. The blurred ones are due to the camera and I will fix them soon. And thanks to all of you for acting civil and smart and good like the old gang. Thanks for many fun emails and ideas too.
On the DYNO data, I own the entire collection and Stroppe and me, the gang, we only authorize you cool cats to look, we do not grant any person the right to re print or use the logos,data or facts please. Until this day, only former FORD team guys have had access, and this data is the work of the Stroppe team before and after the HM merger, and during that period when we were a team. We just want to maybe use all of it for an engine book some day and for authorized history sources. I was asked to say the above so thanks.
A few guys claim I wasn't there, so, maybe they can explain how I have all the data...so odd..
It will be fun to be engineers and study this as friends.
The pictures have some cool details;
1) I wanted new FE guys to see how to ID a SOHC block. Look for the big H. Hee Hee.
This is a NOS std bore 1966 H block and is high nickel. I want the guys to see that big H on the back. That is the Hemi block and has an extra hole in the rear of the deck for the heads to drain back to the sump.
So for new SOHC guys, the head gaskets merely have an extra hole in the rear or the blocks deck, and a boss.
One machining operation I/we did was to add the rear drain hole to 427 blocks that have the boss. It is a tricky passage, down, then angled. You drill in a Mill from both sides with a fixture and special drills an reamers. Well we did it this way.
Later in the 60s, some boats and Drag cars used the standard block, and we drilled and tapped the heads in the rear, to not need these drains in the block, by directing the drainage by AN lines, down to the pan. Some saw a little more power normally aspirated,but in a Pro Car there was a school of thinking. Safety.
In a Dragster or a Funny car, Altered, we liked the stock drainage because adding 2 big lines, adds several chances for them to leak , maybe oil the slicks, maybe close in the driver(Oil his face shield-blur his vision), or, get on the headers and catch fire.
Many thought the FORD design was safer for extreme uses. We did.
2) The FORD blower intakes;
We are mocking up a pushrod HEMI head for an FE, an evolution from the Mickey Thompson FE HEMI that was FAST back in 62-3. That set the Gas Dragster record and was neat. We built some too. Notice the port spacing. The SOHC came on the scene and began to beat the 392 Dodges for several reasons. One is the ports, compare please. Also the bore spacing, see how the ports align to the right, and that big old powerful FORD is wider, thus bigger bores, thus further valve unshrouding and more displacement, and flow. That stock iron port was good for over 400 CFM rough cast, and a lot more finessed. Add a blower and bye bye Dodge boys.
There is symbolism there too. The 392 was fast blown, and won and won. The FORD did the SOHC. And they won and won. So the SOHC stopp on top for a long time at many races. The SOHC became the fast way. It remained the fast way until FORD ran out of blocks, and DONOVAN made a dedicated aluminum sleeved 392 block, called the 417. That could have been a FORD FE block, we all asked,begged, hoped. Once the 417 proved it's mettle, and the FE blocks dried up, the 392 gang had the next edge.
3) X braced blower intakes. Ford began with 2 intakes cast out here by Buddy Bar. Many X or SK castings were done there, we machined plenty. The X brace show that this is the V intake.
The flat floor intake was very dominant in Funny Cars like my all time favorite, The Going Thing
Nobody won more than the legendary Tommy Grove. He is such a fine smart guy and he is fine and well. I'd shine his shoes too.
He ran the flat floor intake, and a special plate. I am re doing this fuel system now, very unique, very fast, very reliable.
The fastest Dragsters evolved to this style intake. The X on the bottom is a clue to older cats here. The X braces the florr of the intake, which has a V in it. The Super Snake, Baney Pink Prudhomme ran this one. We always loved that car and it ran this style intake. The pop off is in the rear.
Now why would you build a blown fuel engine, for a front motor car, and point the pop off at the drivers face? To keep him alert.hahahahaaaaaa
The pop off didn't relieve often, we did rarely see a hiccup at night, and a flash back there, but the deal was, the front of a Nitro Cammer is busy with the mag, fuel pump and related. It fits clean out back. Many ran a block off too, I have a new M/T one shown. Chromed.
4) Flat bottom blower intake tricks. This deal will have a special plate from the 60's to make the fuel distribution more even. I show a 2nd design cover for the new cats. This one clears the adjustable rocker. Also, note the chrome filler tube.
Back when, you could tell what was inside a cammer by the covers usually. No added breathers, carbs and gas. One added breather, blown gas,injected gas, alky, fuel. 2 breathers per side, AA/FD or Top Fuel, AFX blown, Floppers.
5) The dang camera blurred ! Sorry. Just billet special SOHC cams, reground. Many of the fastest cams were cores with changes to suit the car
The rollaway is from back when, with many of the FORD team decals and so on that we only used in house or on our work. Heads, prototype big valve wedges
6) Crane billet blower cams. One of my old team tool chests with an employee only sticker or two. A few guys elsewhere questioned my years up on The Hill, only employees had these lgog deals. Metal sticker, Sid Waterman. Genius fuel system pal who is faster than fast and sharp as a scalpel. Sid changed the sport for everybody
7) Billet blower cams. These are CRANE 646 Nitros. I wanted to show a trick. The 646 is ground down on purpose, and the etching is by a key cam vendor who reground them to be a bit more stout. This shows how many good cam companies, re did many SOHC lobes.
ISKY did special cams for the fastest blown gasser for example. We all LOVED the MALCO Gasser and he ran many special ISKY SOHC cams. So did we. ENGLE, HOWARD,CROWER,MOON, MADDEN, GENERAL KINETICS on te carb cams, CRANE, a huge influence. Many ways to fly then.
For new guys, the stock SOHC cores are cast iron. Great bump sticks, fast. You can only regrind them so far, so billet was the next step. Billet also corrodes less. after running injected or blown fuel, or alky, that attracts water thus rust, the cast cams will get pits. If you find old SOHC cams with pits, they ran Nitro probably. The steel didn't pit and could yield a bigger lobe, and profiles with more area under the curve, and they lived better in some builds.
8) I gotta get to work.......more soon pals
The edits were spelling. need to check the spell check closer here.
ALSO I did this entire essay last night, and one quick click erased it all.....So I tried again today. One quick click, and the typing firld went blank. My bad I am sure.
Thanks so much guys

Love the 515 HP out of the 390 engine :)Saw Tommy Grove at Minnesota Dragways as a kid.I eat this old stuff up!
-
Wonder how long the sweeps were on that 428 dyno? I've never seen an engine pickup 20 degrees of oil temp unless it was hurt....
I'll bet they were static pulls, Brent. Remember, this was 1969, and most dynos were not computer controlled, and the data was not collected in an automated fashion. This was explained to me once by somebody, can't remember who, but they would run the engine up to the RPM of interest, get the brake set, read the scale (!), hand record the other data they were interested in, and then move the engine to the next RPM point. Or, maybe shut off, look at the data, and then start again and go to the next RPM point. If they were operating like that, it is entirely possible that the oil temperature would go up significantly as they gathered the data.

Hehe, I gotta git me one of them 4.25 inch bore 390's Limabean :P

8) The FRANKENSTEIN MAG's
This is a rare and powerful Frankenstein magneto that only the fastest teams used to win.
They sparked so hard, guys joked that they might be able to get old Frankenstein himself up and running ! Funny, to me.
In the late 70s, 10 years after their debut by Cirello, that is great, a Frankenstein was still worth a solid 500 bucks. about the cost of a block
To do a period correct digger or flopper, like one of the Don Long or Woddy Gilmore Fuel SOHC cars, this is the Mag that won.
The smaller mags were good, but the added amps and the internal coil here, provided a safe ignition system that would not drop cylinders.
Blown, dropping a hole or two lifted a lot of blowers. Lose the spark, load the holes, spark. returns, BOOM,,,,we saw many rotors blast up up and away when a magneto lost it's mojo.
On a blown SOHC, there is no hole for the distributor
You mount the mag on the horizontal plane. It gets driven one of 3 ways.
Off the front cover driven by the stub cam, these you see centered down low. Or, Driven off the fixed idler, up high, in front of the left head and cylinder 5
The great, gosh we love his work, OHIO George made a dual drive. We made a small run too. Mallory helped. These are trick. The dual drive mounts to the fixed idler, again, high up, by the left front head, by 5, and the fuel pump and distributor spin. He ran a real nice MALLORY Mag, vertically, and the fuel pump was horizontal. a 2 in one
Now also guys, The Super Snake, had the Mag in the center, off the stub cam, and fuel pump off the fixed idler
Some of our thinking was, better timing accuracy with the shorter dual roller chain to the mag, and let the longer chain span, drive the pump
Today, a Frankenstein is supposed fetch around 3,000. Yikes. And a dual drive, rare as a hen's tooth, again, 3-4,000 they say. We may do a short run again.
Tommy Grove won more than anybody with a special Mallory Mag. We still win with them so I hope you trust and run these stout guys too.
Back then, a VERTEX was OK at about 4 amps
Old Frankenstein could get pumped up(magnets, charged, etc) to around 6-7
Today a stock looking Mallory can do 14 amps easy using rare earth magnets and tricks.
Wanted you older cats to check this old mag out. The fastest guys had that big black MAG. I am sure some of you remember them.
I have the special magneto mounts if you guys are interested. Hilborn made several and so did we, and guys from then. You have a scale on this mag to bump the back up or down by degrees, between rounds for example.
I would add, the legendary Tommy Grove was dominant with cammers and ran a Mallory Magneto with great success. These have the large diameter cap and he had great luck with his Mag on the front of the cover over the fixed idler, by cylinder 5, up high.
Grove match raced up to 4 times a week, ran water in the block and iron heads. He drained all the water after a run. This was common then, you just dumped the hot water, waited as you serviced the car, changed the oil, then after 30 minutes or so, added cool water back.
Grove ran a special one of a kind Fuel Pump, from the stub cam location, down low, centered on the front cover, and spinning on the horizontal axis parallel
I can show you nice guys the Mag mounts soon.
It is like a vacation to just talk tech in a congenial and gentleman like manner, as FORD guys.
It is far more productive and much more thought provoking
Thank you kindly
-
Interesting to see that 100 psi oil pressure.
I like it meself. :D
It would be interesting to see some more of those old tests just to see what those guys were running for numbers.
-
I will add that I've met and talked to Tom in person and he was nice enough to introduce me to Stroppe Jr. We've talked and emailed on several occasions and he's always been very helpful.
Thumbs up FORD man. This new friends DAD was a dedicated FE man from back when, and this cool cat is around some brutal fast SOHC's. Also, he is a good man and fine Father
Best to Dad and the family pal.
I may have some rare 406 HP stuff for you guys some day
Stored 50 years

Here is more data for the guys. Please let me explain soon, thanks very much.
On the blown FE girdle, here is some data to ponder.
FORD needed a solution to the max effort blocks cracking the main webs on the blown stuff. Noel Timney is in the Garlits Hall of fame in the very first round. He was the first Drag Racer to build a 150 MPH car at the first Drag race, and Nationals, in Great Bend , Kansas, Scotty Drove the Bustlle Bomb. Politics denied them the win. They were a rowdy hard fighting gang. Funny story for friends some day
He invented the girdle as one of FORD's and Stroppe's best race car machinists. As a young gear head, many legends told me this and he deserves the credit. I sure was glad to build with him for a long time.
He was my Boss, he trained me in the HMS way to prototype and try to help engines live.
He hired me, and we had a race car shop after FORD ended the FE that was mostly fast FE stuff too.
He did the girdles for many winning rare race engines in the 50s-60's. We were lucky to have a very big and well tooled machine shop inside the center of this big race shop.
This is his design, with all of our input, for FORD, and the very fast guys who needed more bottom end strength.
Deal was, they cost about 2,000 with all the steps, so only a few could get one then. Plus, by then, too many guys were switching back to Dodge due to the DONOVAN and FE parts drying up.
This girdle also helped some very fast SOHC Top Fuel Race Boats. Hydros, etc.. We raced them out here plenty too.
I made several with him. I mounted others, rare stuff. I have the prototype, plans, etc.
Plate chromoly. You pattern it then flame cut the blank on a pantograph. I cut maybe 5? Remember a Pantograph guys? Very trick deal then. A table, and a tracer, and an oxy acetylene cutting torch pointed down. You followed the pattern and cut the rough part out. Many many 60s speed parts started ths way. Thousands of header flanges for example,many race parts.
Then, you rough it out to fit a SOHC block perfectly. These are entirely hand made. Now, these max effort FE's had studs. See the clearance for studs? We made studs because no ARP or SPS was around, no jegs, we made a lot of special race related stud kits
Next, you mount the front cover and center it on a crank. Then, you dowel it, so it stays were it was fit
Then, the block and cover goes on the overhead chain fall, up, and in to a Mill. A horizonatl mill with gang cutters on an arbor.
The girdle is finely finished in a surface grinder too, dead flat.
You mill the rails and cover perfectly flat too
Then, the main caps on 2,3,4 go on the magnetic table of a surface grinder. a nice wide fine finished flat is added to all 3 at the exact same height. This flat is as wide as the tabs you see with the counter sunk allen cap screws. 2 per spacer
Then the caps go on, sidebolts, torqued, then the girdle sets on, with a special paper thin gasket. Note the 6 bolts per side with the larger bore? They allow a hardened nut, to get torqued down, on a stud that is coarse into the block, fine into the girdle. The pan mounts through studs, with nuts
So the 3 spacers get fit now, by surface grinding to a nice preoad. The girdle is interference fit. The girdle, presses firm on the caps and can no longer elongate or cycle enough to crack and fail.
The bottom becomes very strong. It becomes a Y block with longer stronger side skirts.
You add a nice crush, then line hone it all assembled. The mains are now rock solid.
The pan sets on a normal gasket, that sets on the girdle. You also have the sump lower thus less drag and windage
I have the rights and plans to this, and it is very rare
From the mind of Noel and the gang, for and with FORD
Hope you like it, very few have seen these.

Tom, I remember talking with you a little when I first visited 54. Now days I enjoy this lot and what they dive into. Is anyone working on a SOHC book? Time isn't slowing down and the original guys who played with this engine aren't getting any younger. It would be nice to have a written history from behind the scenes of how the engine was made / designed and then what racers did to improve the SOHC platform. If anyone has read the book Racing in the Rain by John Horsman, it's amazing to read about his life and career with JW Automotive / Gulf Racing. A book like that becomes an invaluable resource to anyone interested in classic race cars. There has to be a decent number of SOHC secrets that only the guys who lived in the golden age would know about. With the resurrection of this engine, the how-to's, don'ts and tricks are important to new people who don't want to find things out the hard way with a $40-50k engine.
Thanks :)
On a fact finding note, did any racers run H in a SOHC? Hydrazine is some pretty nasty stuff.

Hello Sir
I get a lot of email and have a bunch of friends into this idea. A bool about the 90 day wonder better known as the HEMI Killer to some of us. I have liked this idea a long time too.
What I have done is begin to compile more data since the FE guys are a real nice gang.
In the last 2 years, here and elsewhere, I have tried to share some things for the new guys to recall or think about as best me and my pals can.
Today, I am sharing some of the parts and have more to let the gang ponder.
I would buy a SOHC book, sure !
My friends an I like books done by racers, for racers and books that dig deep, and find reliable sources. This can take years, travel and money
I respond when asked, the people who could be the huge resources so far seem fine with this idea
If this gets done, I have a iist of the guys I respect most
The order is off the top of my head but the names would be, Tommy Grove, he is a SOHC genius who won 215 rounds in a row, Ohio George Montgomery, who was dominant and a fiece A gas legend. He beat everybody too. Amos Saterlee, he is fine and tuned the Mickey Thompson Mustang that Danny Ongais won and won with. You would need the FORD engineers, so the great John Vermeersch is mandatory. He said he would contribute to the new Holman Moody Stroppe book a while back so that is so nice of him. John is legend to the SOHC world and a smart FORD man all the way. He was there with a spare and crewed for Dyno Don too.
Ed Pink was unbeatable for that period, Kieth Black's son would be great, his Dad won and won. McEwen is a must, he had fast SOHC Dragsters, Don Long and Woody Gilmore would be mandatory because they supplied those fast SOHC Dragsters, Stroppe, sure. Lee Holman of course, he is just great.
Dyno Dan, he built for Dyno Don and is a close friend. We shared the Maverick SOHC tricks with you guys a little for example.
Then the new vendors, and don't shoot me please, but a certain head maker might offer a few words about his 11 wins and helping Dyno a little.
Connie Kalitta would be central, he was so fast and so dominant, he rules the field a long time.
Bruce from HMS is a close friend, and he crewed for the awesome Conrad on his SOHC cars.
I'd definitely interview the greatest, Big Daddy. He could add a huge perspective and is such a treasure to so many.
Robert Pond is key, he has invested so much to help so many
Doug at pump builder deserves his page, to show respect t him for helping provide so many cool new SOHC parts. Fast old Paul Munroe for making heads and intakes, chains and more.
Of course the awesome Champ JAY BROWN,,, This genius and forward thinker is widely admired for pushing the old SOHC into the 21st Century with such passion and ability. We all owe him a lot.
Of course Barry and Blair who build cammers and who are so good. Such awesome FE guru's and they have such fascinating minds.
I am going to reveal this. I did a series of essays about a group of us combining to force feed a SOHC on fuel soon. Barry has twice expressed interest and would be a huge resource to any Drag Team.
and the fine Southern gentleman Blair, gosh he is fast, he was a huge help on this SOHC on Fuel deal. I was sure a team would gel, and the Boss told me to find and buy a famous SOHC dragster since we raced a few...So I get 3 blocks and a lot of stuff. Well, the economy was tight, and people didn't step up, so Blair was awesome to buy all 3 blocks from me. It was good for both of us because I just bought a bunch more SOHC stuff. Thanks.
Think Brent has done some nice ones and he is a skilled engineer and rising star.
William Conley for his smart analysis, real smart cookie. He should be asked.
Cammer Butch has a wealth of knowledge and has a ton of cool SOHC stuff. Nice man, and his helper Ben is cool.
Ed ISKY, we talk cammers at times, he did OHIO George's cams. Ed remembers that fast FORD well.
Clay Smith cams, old Striegal is a genius, and it was him, who brought the Hydrozine out of the oil field and in to the sport. We talked about that a lot recently, on the starting line at Bakersfield. It is virtually undetectable by the tech guys because it bubbles off and disappears so fast.
Lean Gene Adams,boy he tuned a bunch at HILBORN
Rowland Leong would have to be interviewed. He was like a son to Black. awesome man.
Steve Gibbs, Dave McClelland, great guys and just fine.
The Bach and Gould team, for sure. They are legend.
Danny Ongais for sure, he is fine and a great guy. Still building too, local. Man could he drive that Mustang for Mickey Thompson.
SHELBy of course, helped my favorite Top Fuel Cammer in many ways, ARIAs of course, many would be important
I'll make ya a girdle,,,LOL
Thanks now
I'd love it
PS I am tired, I know I forgot 20 people and we can add them
You guys tell us who should be in there please.....Old FORD guys for sure
OH Larry Knapp,,,,he was close to the great Earl Wade and has his last Pro stock engine in a Stroppe car, Larry, for sure. He has 3 cammer cars and has been a cammer guy for 50 plus years. He is re doing the Les Ritchey Mustang
I'd add Randy Ritchey and many more, Sherm Gunn of course, built Dyno's Maverick, Bobby Spears, many good people could help
I'll make the Lasagna....LOL and get ya down the road a bit...
Ha ha ha
thanks
very nice to hear from you pal
Email any time, just give me time please
Fast Frank Bowers of course could add wise facts. Nice man.
Hope it happens. Gosh, it is so nice to just share and not have to see a fight when you say cammer...!
-
Wow, that is a lot of names to pull together for a book. Would take a decent amount of time and lot of skill to piece it all together. I hope I see it happen one day.
Did I read correctly, that a guy named Striegal was the first to play around with hydrazine? Did it ever run in a SOHC? I've read a lot of old racer stories about how dangerous it is.
-
Hydrazine, What's the worst that could happen? ::)
His expression is like, wait a minute! I shouldn't be seeing my rotating assembly right now!

I've read some stories where guys would keep it chilled in their race trailers and what not. Put a few drops in at the line and then dump their tank after returning from a run. The scariest thing about H is the level of protective gear you need. I was talking to a guy who had to procure the safety equipment for his crew, I think he was in the Air Force. He said they treated it like instant cancer if it got on you, which isn't too far from reality. These days you have to wear a hazmat suit designed for toxic gases that are corrosive. Hydrazine is still used to this day for spacecraft as well as emergency generators on some jets. Take a look at this fairly recent photo showing the level of protection you have to wear to deal with H.

If sources are reliable, it is said when hydrazine was mixed with nitromethane it could make an unstable form of nitroglycerin! The oxygen scavenging abilities were so great that it only required 10cc's of it per gallon of nitro. It can also burst into flame if spilled on rusty metal. Also highly carcinogenic. "If it's burning green, it's hydrazine!"

I think this was actually a copper head gasket burning, but you get the point.

I've read the same thing. I watched a video that interviewed an old racer. He said anything over like 2% in your fuel mixture could send people to the hospital from the exhaust fumes. I'm not positive about the percentage but I can believe the bit about toxic exhaust gases. Nothing was safe from this stuff. An engine could blow up simply from having any remnants of hydrazine left in it after a run. The problem is due to nitro acting like a catalyst to hydrazine, as H will consume oxygen and react. This will then serve as a catalyst for the nitro, in turn. The result is a large bang.
On a related note, often the most dangerous fuel tanks are the ones close to empty. Whatever fuel you're running, once the fuel tank level is at the point that stoichiometric combustion is nearly perfect for that fuel, it can turn into the largest bang. This is why a gas can with just a little bit of pump gas can be very dangerous.
I worked for a company when I was in college that specializes in blowing stuff up. I worked on one project where I got to know some of the ins and outs of a rather dangerous test. The goal was to see what would happen if you took a tanker, blew it up to disperse the fuel and then ignited the fuel with a secondary explosion. We blew up 2400 gallons of a regular, everyday fuel and it vaporized a tanker you would normally see spraying water at a construction site. We never found the cab, and one part of the tank itself was found at least 200 yards away and it weighed a minimum of 100 lbs. There are some rather tricky details to making this explosion happen, but when we got it right, we shook the entire town and blew the doors open of a tool store roughly 4 miles away from the test site, with a mountain in between. One of the biggest bangs the company made during my 5 years of college. Imagine a sonic boom at ground level up close and personal, and you'll get the idea. That's somewhat how powerful the shock wave was from the energy released from everyday fuel. I wish I had been outside at the time of the blast, you would have seen it. I have seen the way a shaped charge's shock wave bounces off and then back towards a wall in a zig zag pattern on high speed cameras. That is crazy stuff.

Love seeing the old "girdle" knowing it was from before CNC's when folks designed and machined w/o computer. I picked up out of the trash a early 70s Raleigh "International" 10spd bicycle. (about $1000)While the frame was made in and bike assembled in Carlton England all the machined components were Campagnolo I pictured a fine Italian machinist working a week on just the crankset.

Interesting to see that 100 psi oil pressure.
I like it meself. :D
It would be interesting to see some more of those old tests just to see what those guys were running for numbers.
Hi Mr Scotia FE
The 100 PSI is with Valvoline 40W Racing and is not multi visc oil. We were sponsored by these great guys, and others. Pennzoil was in the AFX SOHCs for Dyno for some time for example.
Bardahl was a sponsor, so were others
We blueprinted every oil pump and I have done them our way a long time. The 2 Cobra Jet tests are to compare the FORD Drag Team 7 QT pan versus a Drag Pan with 9 Quarts from MILODON who has been close by a long time and who would make parts with FORD's guys input and them we would test the stuff.
So you see a long static 2000 RPM break in and there is data not on the sheet. We have to fill in the blanks
On these 68s, geting prepped for the Winternationals, or first Super Stock race in 69, all the Drag Team cars were coming and going from the 'Hill'. So trying to get any edge and stay NHRA legal was one thing
Another was, these engine continued to get built by many of us, to be just like the Drag Team cars, for decades afterward. A customer would come in and say, I would like an engine like ,,,,name the team driver, had, in his Mustang in say 1969.
So, all the guys would talk, even at their later shops, and share these little tricks.
What I would add is. I see these books that claim every CJ car had this list of parts. Sure,as ordered I guess. However, these cras were owned by FORD then leased or sold with conditions, to the Team guys, and then FORD paid us and others, to add tweaks to help win
Tese Drag Team cars were very carefull assembled, the engines were thoroughly blueprinted, tenth tolerance usually, and the target was,,,,,at least 40 PSI hot idling, and about 80 psi under load wide open
If it broke in, got tested, and cycled, heat cycling, that is important, if it had less than 40 psi when done, it came off and apart. This never happened because you basically do them all the same, well here, clearance wise,,
I am not sure if we have met but O/T, I am told that Nova Scotia is just beautiful and would love to explore it some day. You are a lucky man to live in a wonderful land.
Kind regards sir
Thanks now

Wonder how long the sweeps were on that 428 dyno? I've never seen an engine pickup 20 degrees of oil temp unless it was hurt....
I'll bet they were static pulls, Brent. Remember, this was 1969, and most dynos were not computer controlled, and the data was not collected in an automated fashion. This was explained to me once by somebody, can't remember who, but they would run the engine up to the RPM of interest, get the brake set, read the scale (!), hand record the other data they were interested in, and then move the engine to the next RPM point. Or, maybe shut off, look at the data, and then start again and go to the next RPM point. If they were operating like that, it is entirely possible that the oil temperature would go up significantly as they gathered the data.
Hello Mr Jay
Thanks again for all that you do. You have a nice team here.
OK, you are correct as usual and here are some facts.
FORD had the best DYNO money could buy then and we had 2 cells. These legends would come test for a fee at Ford racing for example.
It was really something else, to have the older guys say, FORD funded the 3 most precise dyno cells this side of the Mississippi. This was told to us because we had side by side Heinan Freund dynos on the East end of this mammoth engine room
Bruce CROWER obtained one of them for his private skunk works after we moved because they were very special
The key is, a huge water brake. and a very precise way to load it up and down
The control panel had the highest quality instruments, and part of this was so that our tests, could go back to Detroit in some cases, or down to HM South, and be calibrated for comparison
And yes, running the pulls required 2 men, and a skilled operator with these tasks
You have a level on the console, right hand controls the throttle, like today
Left hand stays on the rotary switch that loads or unloads the torque brake.
In front,, a window to the test cell, and two large calibrated gauges, a big tach, and a big pound scale to measure torque to the tenth of a pound.
So this requires skill because a very good dyno guy, if having a bad day, or distracted, could let the engine 'get away' from him, wing it and bang it.
A legendary FORD engine man had a crowd watching, and was kind of showing off or talking too much, they distracted him in his defense, and the tricky paart is manually mashing the gas, or WOT,,wide open throttle, then clicking in the load, loading the engine, and if it has a lot of juice, it may over come the torque brake and get away from ya, and if you reacted just a bit slow, failed to lift, or close the throttle fast, it might over rev and BOOM !!
He is the only guys we recall who boomed one
427 tunnel port, 14/5 to one,and and
The Foreman usually did the data gathering, Somehow I ended up or was so so soooo lucky to do some of that later, usually 2nd shift and on the weekends or during a thrash to get many cars to the races.
So you read gages, filled in the boxes, and went in and out of the Dyno cells
What was cool was who came up to Dyno too. The first Total Seal rings, Kendig Carbs, the original NOS systems from NOS down the street, the legendary, man we have stories here, Gale Bank did his twin blown Rats there, he has an entire wing of awesome accomplishments in his own wing at the NHRA Hot Rod museum. W would do cam changes, durabilty, max boost tests.
and he an I smelled so much Av Gas on weekend, we were fainting,,,,LOL And he taught me and a few guys helping, to go into a separate room, grab an oxy acetylene torch, open the O2 side, set the tip in your mouth like a cig, then breath in oxygen to clear your head.
He could pull well over 1,100 ft pounds ina super durable build, with ease.
Ak Miller tested there, huge legend and we loved him, Gus Davis, Unser, Gurney over on the Autolite side, he banged a few Offys and just did 2 more to win
OK war stories, gotta work
Static yes, trick, yes, next deal was, how weel she ran on a track. The Dyno was a basis, to them get the real data, a time slip or lap time
Thanks
AUTOLITE DYNO......top secret,,,,,and had IBM stuff, to simulate laps at INDY for example.
Thanks men

Hydrazine, What's the worst that could happen? ::)
His expression is like, wait a minute! I shouldn't be seeing my rotating assembly right now!

Hey Hey Hey.........that is our home track Lion's Drag Strip, called 'The Beach' and 'Long Beach' by the old guys. Spent a ton of wonderful days there and loved it all
We were there that night, some of the gang, and this is the MAGIC MUFFLER car, also called the CT Strokers car
We also...ha ha Have had this picture, but we have one from the photographer's set, and it is on the wall of fame,,,LOL And also was at the prior place, which was a top tier place. This is just a hilarious deal and so funny
OK
he did not get hurt
The cause was over used stock steel rods in part, and a stout tune up and fierce competition you could say
It was like this. We had 64 car fields for only Fuel Altereds at the peak of that era
How bitchin it was, to see maybe 80 85 such Hot Rods, all there to qualify for one of 64 slots, which resulted in a one day super show?
2 rounds for all these cars to make a pass. Then 64 pair off, down to 32 hour passes, 32 to 16....sun begins to set,,,,,,16 goes to 8,,,,,,many cars are pulling out, all that energy of, we won, we lost....
Blown up stuff all over
8 down to 4, at maybe 730 or so, in the Summer,,,, 4 down to 2 around nine ish
then a Final around 10 PM
The cool air would pour in with ocean mist
The track would have all that rubber on it, cool, and the oil downs would be cleaned up
Many cool races like that
I was standing directly behind the Winged Express, heads shown above, when that famous event happened. The car was in the Finals, in the left lane, And that car launched like a beast, flames standing up about 6 feet or so, car kicks it's ass end hard left, he does not lift one bit, stays in it, car hooks left, and a magnesium Halibrand kisses the steel guard rail, deforms the slick, sparks the edge of the wheel, and these bright silver sparks shoot to the sky like a 4th of July rocket, he just rides it out, corrects it to drift right back to the groove, car hooks, loads the motor, screams, gets up on the tires, marches like an army and wins.
Incredible stuff happened there and that picture was in all the magazines and hilarious
This Magic Muffler car, is a 92 inch wheel base Fiat Topolino. No trans blankets and diapers then
a LOT of cars just dropped the trans back then and this was HILARIOUS to see
It was common for new guys, say, on a Wednesday test night, a Thursday open event, during qualifying
We would see it and just roar
and after,,,,the track official would be on the PA, and get kind of mad, due to the show being stopped, they had to be done by 10 PM, so. they often played that famous old Circus Song to kind of tease the guy who blew up.
To kind of laugh and tease......so funny,,,,,It is that Big Top Circus song that they use to open up a circus...LOL funny
Scott injector, 6-71, note the trick Delta Drive,,,,made at our place in part, we sublet to Delta for a while
Let's see...not so sure the ran Hydrozine but might be able to catch one of them some day
On Hydrozone, that is a long one, for after work
Thanks now

I am not sure if we have met but O/T, I am told that Nova Scotia is just beautiful and would love to explore it some day. You are a lucky man to live in a wonderful land.
Sure we have Tom. I'm Howie Merrette from Nova Scotia.
We have conversed many times on the spiderweb. ::)
-
Ahhhh
OK, you are andretti's friend,,,,ahh from 54....spider web? Is that the nick name for 54?
OK Thanks for the uploading and have a fun weekend
Lets see
If I can trust you, to not publicize some content, maybe with time, I can show you some of the stuff.
Blair, Brent, barry and other friends have seen some of it
Jay too of course....and friends we know of course
Just promise to not forward it to any of these, well,,,people who lake manners or who smear and so on, invent, go OT all day
I have 5 FORDS
Thanks

Is that a quote from the book "How To Win Friends And Influence People"?

Howdy
Wow, that is a pretty Mustang and I have had a 69 MACH a long time too.
Please post the pictures if you like FORD man. It loads and says, file too big for me. I don't have a fast way to modify the images and could use a new program, for later. You sound like a smart tech guy so thanks.
I sent a private email and the point is these parts and logos and the tricks inside, that was FORD property, and then ours, now we just want that Bill Stroppe's fast gas decal to get re done, not plagarized, and we want the design on the part to remain from our blueprints and dimensions
I get told to protect the logo, designs is the deal.
Also, yes, I don't want to fight with guys we don't know about FE's and neither do my old pals.
This email you just posted, for example, was to a friend and not for the blog
But no problem I guess
Not trying to win friends, influence people sir, just showing some old parts
Sure dont want to fight about parts anymore
I would appreciate you deleting this quote, I made a typo,,,LOL Lunch is over
See who guesses right. 4 parts total. Nice to get acquainted, my name is Tom
Thanks now
Happy Friday

If you need some image work done, you can email me. My email is jbauer127@gmail.com. Just send me the images and I'll do what I can to sharpen them up.
I found a decent Stroppe decal online for example and did some work on the contrast as well as getting rid of some of the odd stuff in the white background. There are two versions, a jpg (2nd image) which has a white background and a png (1st image) which has the background deleted. Png images are useful for shirt printing and website use. I can resize logos if needed. This decal was a quick 3 minute job but I have restored images in the past, at the pixel level if needed. I'm currently working on the new coiled snake logo of the GT350. I found a good picture of the emblem and I can use it to get the coiled snake black and white image.

Wow
You are talented my friend and you did a wonderful job. Thank you very much from all of us. This is the decal from the 40s and the 1950's, up until the merger with Holman Moody.
Ford came to Stoppe in the 40's because he and Clay Smith, the cam and racing legend, were best friends who built Hot Rods from their early teens. By the 40s, they had been winning a lot of boat races using only highly modified flatheads.
As regional Champs they were invited to the big national event in Michigan and qualified first and then won. Henry Ford himself came up to Stroppe with his friends and asked Bill; " How are you making my engines so fast?" They had beaten all the Ford backed boats, and the private racers.
Stroppe began to explain part after part that they made from scratch out here, including cams, pistons, special heads, stroked cranks, hot magnetos and better rods. Many more tricks too
So Henry Ford asked him to come to Michigan, sign a contract and lead his own divison
Bill said I have to think about it, ask my family and friens who helped. He returned West, then called a while after to explain, he could do better things here because he had a big shop, many trained men, young kids, and this was key, he could race all year and test all year due to mild weather. There's no freeze, snow and little rain, and there were test locations always available
So that made sense, the more you test, the more you learn, so they made a deal. This deal lasted for the following 6 decades and finally ended about 5 years ago due to illness and budget issues.
Today, a 125 man team may service 1 or 2 stock cars for instance, but that was our peak head count, and it was never less than about 60 guys, usually 80-85
Thanks FORD and thanls Bill. The rule was like this, FORD Racing West, the Stroppe shop, he only hired the very fastest guys he could find from any part of America. So FORD sent us many great guys, so did other teams. It was kind of a shock to meet these guys, then hear their resumes. Many guys were former drivers who built their own cars and engines, like many of you guys.
Stroppe had a big heart, so if a Sprint car driver was good, and got noticed, and won, then got hurt,which was common, he might give them a job, especially if they had a wife and kids to feed.
Here's an example. Les Ritchey was a famous FORD driver and builder that won many races and who was so good. We lost him when his shops best car, the Performance Associates Mustang, crashed. Some of our guys were at the race. He had 5 good men, and all had kids. So Bill hired his 4 best guys to be a good man who looked out for racers who ran FORD's
One, was a stand out engine builder, who went on to help inspire the SHELBY aluminum FE's, which kind of reignited FE's in many ways. This was my old Pal Wally Cartright. ask around, Wally was a fast Ford man who built for the best,including ed Pink. Knew him well at the shop.
My good pal is redoing a CAMMER fastback Mustang replica of the Les Ritchey car right now. I am trying to help, find rare parts, and have Stroppe in the loop and others.
5 of the old gang are meeting tomorrow
Stroppe went on to do FORD protype work and flatheads, a bunch of Y block 292-312 work, then the entire FE run, from 332s,to racing 352s, 390s, until the 80s, in offroad, 406s, the MERC teams, 427s,428s, BOSS 429s, 351C's and a lot more. We had The Ford Drag Team the entire time, part of the GT40 work, some Bonneville, Salt, Boats, stock cars, road rally cars, we dominated Off Road for decades in 5,6,7 classes often, we had all of the Pantera programs, the Lotus Cortinas, and so on.
Thanks so much ! i will show the guys, maybe use this on Shirts
Thanks
Will email 5 more pics
Look forward to meeting you
Best

Wow
First, that color is just, it moves me it is so deep, and straight and it pops and look cool man
Reminds me of MANY famous race cars color. Really nice car man..!
The INDY AUTOLITE dyno had less servos and automation and was smaller than the FORD EEE compound but it was very high tech, in part, due to all the Aerospace around here. It did have a set of mainframes for a while, and was used to simulate an entire 500 mile race, with cautions and restarts. The blown alky INDY program vented the exhaust through a block wall and between the big buildings. It was so loud some men got dizzy and sick. It would go non stop all day, funny
I have to add the comments and post and then Hydrozine and the rest
Thanks !!

So here are a few more pics from Tom. He had this to say at the time of the email...
Here are more Drag Team parts by Ford and Holman Moody Stroppe
A few helped FE's run in the low 7's.
Wonder who knows the details?
Will add the descriptions soon and thank you ! Hope you enjoy the old parts. Many were FORD team parts, given to teams, SK parts, with no part numbers and unavailable at a dealer.
We had the FORD Speed Parts division that could make and supply some parts. They went with a sponsorship basically.

Tom, if you can send me any good pictures of decals and logos you like, or have paperwork with the logo you want, send the images to me and I'll see what I can do to restore them for your group. If you look at a previous post of mine, someone has stickers with the HMS logo.
-
Thanks very much for the emails and help
I promised to explain the pictures so continuing on
9) The iron SOHC head you see is from one of the original 500 made. For the new guys, the heads have etching on the cam towers and camshaft caps that have the production number. So it is cool to find these from the original run and I wanted some new SOHC guys to see some old FORD HEMI stuff. For fun.
We see so many that are cracked from Nitro, or welded many times, surfaced a lot, if you look close, these heads have never been surfaced. Note the depth of the chamber along the OD of the circle. Also, the original drag broaching lines run the length of the heads here, so they never got cut. Drag broaching is kind of like planing cast iron with a stack cutter.
Many many Cammers were also sold in parts, in fact, many original FORD team guys got their first SOHC in parts shipped by FORD or obtained from Detroit, or us. So those heads are NOT numbered as these are.
Also guys might notice, the blown heads we o ringed. These are not o ringed.
-
9) Top view of Blower Intake with rear pop off. Note the long gentle V on the floor of the intake. These were common in Top Fuel or AA/FD and had many fans. Note the down nozzles are close to the bottom, and they have a nice shot at the intake valves. Front pop off versions were also around.
Also CRAGAR made the last and very popular intakes too.
When a blown cammer car launches, the fuel that fell out of separation can accumulate on the bottom of the intake, and rush to the rear, then fatten things up a lot. So, if you bias more fuel forward, the balance makes better power.
No remember, much of this testing was done by plug reading, and by flame patterns, and by valve colors, after runs, and by piston colors, after runs, and by leak down, after runs
No Racepack data on Exhaust temps and so on.....
One trick we still use real quiet, on these Nostalgia Heritage bombs, is to count the threads on the spark plus and see how the edge of the threads 'rolls' or melts back.
And of course, how much of the ground electrode burns away is key. Each pass, melts the plugs a wee bit, so that observation is very important.
10) SOHC front covers. The 65 could have a little porosity which was fine. This one was metal finished, has some tiny pits that do not leak, but, to run in a top class, some did chrome them and this is show chromed from the 60s. Also, the back plate for this SOHC is also triple chromed.
The natural finish was on many of the fastest SOHCs we saw, so this finish was no speed secret but real pretty.
Next, for the new guys, you see 3 openings on this cover
The low circular boss, is over the stub cam. Blown SOHCs usually got a gear drive installed.
This location carried many MAGNETOS or fUEL PUMPS. It depended on the tuner and builder. That famous Funny Car ,The Going Thing, had a huge fuel pump in the center location. I mean, huge and one of a kind.
The Super Snake,that wicked tough Baney Pink Prudhomme dragster, the SHELBY Super Snake, PINK ran the magneto was here. That Don Long car is just a work of art, and, the sissy bar car is under restoration. I hope to have time to get you guys some pictures for fun.
Now the large openings up high in front of the heads, allowed access to the cam gears on each side.. Looking forward as show, the Left opening gives you access to the adjustable idler which you might re tension from time to time at the races.. The right side head, has a bolt on a ear cast in the head to tighten or lossen the chain tension.
Dyno Don, would sometimes change this tension to move his cams a bit between rounds! He was a Cammer virtuoso to many of us. Never met a better driver or seat of the pants tunner and track reader. He was a genius and wonderful man.
The opening on the right, had a plain cover stock, when removed, the fuel pump eccentric was on a gear called the fixed idler. You turned the eccentric off of the gear for the blown stuff, in a lathe,, added a cap screw or broach, then changed the cover to a Hilborn cover. That cover, accepts the rotory fuel pump for the injection. The cover is cast, has a retained roller bearing, and the drive slide in it, then you bolt it down. I have a few if you are curious
The square MT item is a blower relief block off plate. It has an o ring behind it But by oring I mean, Square ring..LOL
-
Now to the second set of pictures
Next, an iron SOHC head, NOS,with the later stainless DONOVAN style valves. Some guys thought that a bigger 1.94 exhaust valve, like a 426 HEMI, was trick. This pair had that trick, I will replace them with the FORD size most likely. Not needed if you ask me.
Also, 4 hole HILBORN Scoop which was common. Notice that the holes in the scoop align close compared to the bore spacing on the head? The blowers 'HAT" supplies 8 nozzles, 4 per side. So they wet the blowers rotors, and cannot shoot directly to the intake ports. Adding 8 more nozzles was the hot tip, still is, so you mixed the two systems.
Non supercharged Injection, port style, has the butterflies close to in line with each port, so you run 8 nozles, one per hole, down low.
I have heard guys call these 'down nozzles'. We call them port nozzles around here. Down nozzles are in the port through the heads, a 3rd row of nozzles
Also, a blowers helix opens first in the rear of the intake. Look at the twist in the 6-71, spin it slow,and see the pressure begins in back and then it moves forward as it spins. The fuel goes from back to front.
This is why the fast intake has the blower as far forward as possible, and, why you can have port nozzles on a fast blown HEMI, up to 15 steps different in size, smaller out back some times, bigger up front
On the hat nozzles, two schools. Many fly, and we have flown, just running 8 equal nozzles spaced normally, 4 per side.
HOWEVER,,haha, some of the fastest cammers,,,,,,had 5 on one side and 3 on the other to address fuel distribution. One leading car, had 5 as for forward as the could mount for example.
The difference being, none of the blowers then were stripped. (No teflon to seal the lobes on the rotors) The were very trick, to run very close, and tight, but without strips, one leading Ford SOHC team, even added a special diversion plate to force fuel forward first.
Imagine the big blower opening you see on the intakes I posted, that big pair of square openings, married, then reduced a lot. You add a special part and 2 gaskets

What happens when you have a H scratched block with no provisions for SOHC oil drain backs
-
You can use 2 fixtures to add the drains as long as that boss is there, at the lower rear by cylinder 4 and 8
Good luck with your SOHC, email any time Ford friend

HYDRAZINE
This was always illegal and deadly. Best we can say, is, GS from CS, took it from the oil field to the Drag Strip
He kept on a shelf, by his desk, in a ordinary container. He kept a glass vial with an old style glass dropper with the rubber bulb? Called an eye droppe back then
Anybody who wanted to try some, if they were cool, he is a great guy, he would just hand them a vial, and say, use half a shot just before the run
Little fuel would be in the tank after a full run, and the Hydazine evaporates really fast, a few minutes, and then is un detectable
Now a Hall of Fame SOHC Funny car pilot, builder,tuner did go to a big chemical company out here to ask questions about it.
By tehn, they were just banning it fr sale to non commercial entities. He was told, and this is true, in the wrong hands, a 5 gallon stell container, set in a parking lot, under hot sun, and handled wrong, could, blow a huge crater in the parking lot.
That, might slow your Drag TEam down a bit
The funny car looks like she is 'torching' the head gaskets, thus that green look....looks way lean too
Thanks
