Member Projects / BPE 352 pet project
« on: November 03, 2019, 11:00:14 AM »
I've been collecting pieces for a while to do this.....I've wanted to do a "max effort" 352 all my life. Here's what I have on my mind, and about half of it ordered, or on the floor now.

* Sleeved down "worn out" 427 block
* Scat forged 3.5 stroke forged crank
* Crower 6.590 length billet rods Honda 1.888 journal
* CP pistons with domes to fit Pro Port chamber
* "Race" version BP Pro Ports 2.200/1.600 valves
* 52cc combustion chambers
* 14.5 static compression
* Steel bushed T&D
* .937 Crower Enduramax bushed lifters
* .900 lift, 60 mm Comp Eliminator profile camshaft
* Danny Bee belt drive
* Worked BBM tunnel wedge
* Two 1030 cfm 4150 carbs

Planning for 10,000+ rpm.  I am building this for my own toy, but if one of the Gasser guys wants it, I will probably sell it.  It's just something I have always wanted to do, so I think over the next six months we are going to try to work it in. The goal is 2.3 to 2.5 hp per cube.  Stay tuned.......

Vendor Classifieds / CNC iron heads
« on: October 19, 2019, 07:41:09 AM »
Well, we sold the heads off the Engine Masters engine before we got home.  We cut four more pairs last week, three of which are also sold.  I have one pair currently not spoken for that is ready for finish work.  We are selling the heads for $2200 including valves and all finish work, ready for springs, at 75cc chamber volume.  We can mill more for a minor additional cost.  I would stop at 70cc to leave plenty of deck thickness.  We ran the contest heads at 71 cc.

If you have heads that you want to have ported, we can port and do all finish work, ready for springs for $2K.  The programs will work on any LR 427 castings, C4ae-G, C6ae-R, Cobra Jet N heads, and most any other Low Riser style general production FE heads.  I try to run four or five sets at a time, as there is a set up change for doing iron castings on the cnc mill.  If interested, contact me via email at captcj at hughes dot net, or call the shop at 423-837-1514.  Email is the best for initial contact.  Thanks very much.

FE Technical Forum / Amsoil
« on: October 05, 2019, 09:00:22 AM »
I am an old dog at this point, and I have been religious in my use of Valvoline VR1 for a long time.  We bought Valvoline racing oil way back when you needed a screwdriver to poke two holes in the top to pour it in.......unless you had one of those fancy pour spouts.

Amsoil was the required oil (and a major sponsor) for Engine Masters.  They sent us oil to test with, and furnished oil for the contest.  I was reluctant, but I used it from beak-in, to their synthetic......through our 24 test pulls.  We had to show up dry, and they gave us oil at the contest to prevent the possibility of performance enhancing additives. 

I looked at the break in oil and first filter pretty closely.  I also looked at the second filter and first oil change closely.  I liked what I was seeing. We made 9 or 10 more pulls in the 35 minute scoring window at the contest.  We had to pull a rod and piston for teardown at EMC.  My suspicion was confirmed.  The rod bearing litterally looked like it had not been run. There are of course factors of supply, clearance, and temperature that contribute, but the oil definitely did what it was intended to do. I have a very high opinion of the Amsoil now, and thought I would mention here that it is worth looking at for both a break-in and a "run" oil.  Very happy with it!

Mine is .575 lift also, after lash.  Same rules as Joe and Barry.  Mine is a .046 overbore 390, 3.79 stroke, and I used C4AE-G heads.  Works out to right at 400 cubes.  (mbrunson you can't guess in this game!)

FE Technical Forum / Jay Brown Timing Cover
« on: September 14, 2019, 10:28:21 AM »
I realize this is the wrong spot but I am trying to find a Jay timing cover with the removable front plate as soon as possible.  Mr. Jay can send me one, but not before next Friday.  I need one in my hand by Wednesday to do some testing on my Engine Masters junk.  If you have one on the shelf and would be willing to send it to me, I will replace it.  Another can be in your hand in about ten days.  I will pay all shipping.  If you can help, please PM me on here.  Any assistance much appreciated. I apologize for using up the space on the tech page, but trying to make this happen......

FE Technical Forum / FE DOMINANCE
« on: September 01, 2019, 05:59:08 PM »
Some of you guys may follow the Indy Nationals, and some may be unaware.  Ray Paquet continues to dominate SS/A class in NHRA Super Stock.  He laid down an 8.55 in class eliminations in his Thunderbolt, on his way to winning SS/A.  About two tenths ahead of the next fastest A car, and some of those other guys are not slacks!  Congrats to Mr. Ray.......still running an original Dearborn Steel car, with modern upgrades, of course.  For those who don't know Ray, he is a prince of a guy.  An honest man, very smart, very quiet......all business in Clermont, Indiana for many years.

Long live Ray and his High Riser!!

Vendor Classifieds / C4AE-6090G head castings
« on: July 13, 2019, 09:52:41 AM »
I am interested in unmilled C4AE-G head castings.  Probably can still use if they have had a valve job or two, as long as the valve size was stock.  I just finished some new cnc programs for 2.150 and 2.09 intake valves, and 1.65 exhaust. I can use milled ones, but would have to shim them in the fixture.  I want to sell some of these after some more testing.  These programs will work on C6-R, Cobra Jet N heads, and many other Low Riser style castings. I just need the G casting heads for a particular purpose I have gotten myself into.  If you have castings you want to part with, heads you would like to have ported, or would like to buy ported ones, you can contact me at captcj at hughes dot net.

Thanks very much.....

FE Technical Forum / "Flow numbers"
« on: June 20, 2019, 03:38:05 PM »
I sent a set of "Race" Medium Riser Ed Pro Ports to a new customer.  In talking with him prior, I could tell he had been around the block at least twice.  He asked me what they would flow, knowing that benches and methods vary.  I asked him to just trust me and try them.  He said he would, so we did them.  He owns a Superflow 600, so I suggested he flow them on his bench after he looked them over.  I prepped them for .700 lift.  He sent me his findings.  2.250 valve on a 4.310 fixture, 28". 

.300    232
.350    250
.400    280
.450    305
.500    332
.550    345
.600    360
.650    365

I thought I would post these third party(flowed by customer) numbers, since people always ask about numbers.  These quit at 370.  I could valvejob them differently and make them go about 15 more at .800-.850, but the application didn't warrant that. Exhaust went 266 up top.  These are about 15cfm better than the "Street" version that retains a MR location.  This port requires some intake work, pushrod tube relocation, and offset rockers, but still a "Medium Riser" style head.

Vendor Classifieds / 445 engine for sale
« on: May 08, 2019, 01:27:31 PM »
We built this engine and dynoed it a couple of years ago.  It has BBM heads with my prep.  93 octane friendly.  240/248 hydraulic roller.  Made 580 hp with two 600's on a BT manifold.  Has a 31130 Milodon front sump oil pan. Has about 500 miles on it.  Owner traded it in on a 482 combo.  I sold this 445 to a second gentleman.  It never left my shop.  Second owner has since changed plans.  Engine is for sale now.  I will install a port matched RPM manifold, and furnish a carb and dyno if desired.  Price is $12000.  Does not include carb or dyno in that number.  If interested, my email is captcj at hughes dot net. 

Thanks.

« on: May 01, 2019, 01:02:31 PM »

Vendor Classifieds / WTB: C4AE-6090G head castings
« on: January 16, 2019, 09:16:33 AM »
I am looking for four cherry C4AE-6090G head castings.  Heads need to be uncut from OEM level, and all valve seats need to be in generally good condition.  No seat inserts or sunken seats, especially on exhaust.  Guide wear is not a problem.  All 3/8 threaded holes need to be in good shape. Let me know if you have some good ones that you are willing to part with.  Probably a 75% chance we will use them for an Engine Masters effort.  captcj at hughes dot net. 

Thanks,

FE Technical Forum / Marine cam specs question for Werby
« on: July 01, 2018, 12:31:47 PM »
Hey Werby, do you have specs for mid 60's 427/300 hp marine cams in your file?  I am going through a standard rotation engine.  I want to convert it to a hydraulic roller.  I will upgrade it, but just curious of the original specs.  We will, at some point, do the reverse engine......I'll have to use a round lobe core to make a reverse rotation hydraulic roller, but first things first......thanks for any info you can share...

FE Technical Forum / So we did a little testing last night.....
« on: April 14, 2018, 11:59:51 AM »
with Grizzle's new ride, at the local 1/8 mile track.  New car, new engine, etc.   All went well, but the converter turned out to be waaaay too loose.  A good converter slips 4-5% in high gear, at the most.  We had the converter built with a 5800-6000 flash in mind.  Turned out  to flash 6950, and had 18% slip in high gear.  We will have to use a 9" converter like the 385 boys employ.  This ragged FE just drove through the 8" that was tighter than my usual go-to nostalgia piece.  With the new car quirks and the wrong converter, it did manage a 1.16 in 60', leaving at only 3000, and it went 5.30 at 130 mph.  With the converter that loose, it was in high gear right past the tree.  We were mid 11's air/fuel, so some in-car tuning is going to be needed once we change the converter.  I see 1.10 60' coming, high 4's eighth mile, and 7's in the quarter, when it all shakes out.  2800 lbs.  Stay tuned......

I keep a few "shop jobs" working through the process in addition to customer jobs.  I have a few here nearing completion.  If any of these catch your interest, give me a holler.

1) 466 cube street stroker.  Really nice "A" scratch 428 block, 4.250 stroker.  It is fresh .050 over, really nice cylinders, CP pistons, Scat 9000 crank, Scat rods with 2000 bolts, internal balance. Well preserved block, no rust, nice lifter bores, oil mods.  I am at the point of selecting heads and camshaft.  Will finish to suit.

2) 385 cube street 390 based engine.  400 rods, hypereutectic pistons with custom ring pack.  Short duration hydraulic roller already in there.  4.090 bore.  Ready for top end.  Would prefer to finish per your needs.

3) Nice 390 shortblock.  It is technically a "legal Stocker" shortblock.  Full prepped Ford rods, CP pistons, sitting ready for a cam and top end to fit the intended use.  I was going to use this engine in the Dueling 390s 2.0, but I plan to build another with billet rods for that..... the rpm and power level of the solid rollers may not be a good fit for this one.  It is prime real estate for a healthy flat tappet or hyd roller.

You can PM me here or email at captcj at hughes dot net if any of these strike your fancy.

Thanks much.
