FE Technical Forum / How would a 550 HP 427 FE get any air to make power?
« on: June 25, 2022, 09:17:54 AM »
In the typical 1965 Cobra setup shown here.  Amazing they ran as good as they did! Supposed to be an exact recreation of first Shelby 427 Cobra.

Non-FE Discussion Forum / Those cool looking Ford Racing 427 Cobra valve covers...
« on: June 13, 2022, 07:07:37 PM »
The ones for the 351 Windsors punched out to 427 cubes.  Waited a week to get them from Ansen who makes the for Ford.  Go to put them on and
find they hit my roller rockers before the bolt holes come anywhere close to lining up. When you see how they angle the sides in and out for the "look" compared
to my old ones that is why they hit. Damn shame as they really look great!  You would think being a race type tall valve cover they would make them wide enough
to clear roller rocker arms!!

FE Technical Forum / Why didn't Ford use a better camshaft in the 428 SCJ engines?
« on: June 09, 2022, 10:49:51 AM »
When the 428 CJ came about in mid 68 Ford just grabbed the old 390 4bbl GT cam and called it done. Maybe an okay choice for the general use with mild gears auto trans and A/C options.
However did they miss the boat a bit with the SCJ package ?  If I remember they had a better camshaft specd out for the 50-100 cars that were built for NHRA class racing.

Non-FE Discussion Forum / Battery charger issue.....
« on: February 04, 2022, 03:04:27 PM »
Have my old Sears Heavy Duty charger/booster and it has worked well for over 25 years. However now when you hook it to a battery for a charge the voltage jumps
to 15-16 volts measured at the battery while charging. Of course I shut it down so as not to overcharge the battery. Battery was at 12.5 before any charge.
Output at the charger leads with no battery hooked up is 13.7 when in the slow charge selection. Charger never used to act this way.

FE Technical Forum / Need a Holley carb parts expert....
« on: September 14, 2021, 08:59:16 AM »
Can someone tell me why the Holley 4224 660 carb takes a Holley 6-508 needle and seat vs. the 6-506 which is listed for the 1850 600 carb? This info straight from Holley carb and parts catalog.
Both are exetrnal adjustment and both have same .097 sized hole.  Call the AED shop down the road and they didn't know of any difference but they make there own needle and seats and use
their same external adjustment needle and seat for all Holley carbs with various feed hole sizes being different.

FE Technical Forum / Intake manifold plenum design differences.......
« on: August 19, 2021, 06:43:27 PM »
Does one style plenum design have any advantage over the other?  Comparing the Edelbrock  split log style to Ford's 4 hole crossways plenum. Other OEMs used the log style too.

Non-FE Discussion Forum / SS/A vs. AA/S ?
« on: June 30, 2021, 08:47:51 PM »
What the difference between the two classes?  I see where a 1964 Thunderbolt can run in this AA/S and SS/A so what is the difference between car setup?

FE Technical Forum / How much seat run out after a typical valve job?
« on: August 20, 2019, 08:05:47 AM »
And do most shops use stones or profile seat cutters today?

Long story on my brothers 20 yr and going engine refresh.
He talked to me for almost 2 hours on the crappy valve job he got done 49 yrs. ago!!! :o :o.

Yes he bought a seat run out gage to analyze his cylinder heads which have about less than 1000 miles since rebuild 49 yrs. ago!! .002-.008 run out depending on which seat you check on the cast iron head seats.

FE Technical Forum / Race Gas fuel additive.....
« on: July 31, 2019, 10:22:22 AM »
I decided to give a can of this stuff a try just to see what would happen in my aluminum headed 10.3 compression
427 Windsor after reading and hearing about results of it.
Bought the 16 oz. can and dumped it in about 8 gallons of fresh gas in my tank.

Over the weekend I have noticed that the engine will cruise a bit smoother in 5th gear/3.50 rear gear 45 MPH @1500 RPM.
Also noticed the engine temp runs a little cooler.
Can't really tell if there was any improvement in additional power but it just runs smoother at lower RPM.
I left the ignition timing where it was at 32 degrees total.

So at 18 bucks a can it's cheaper than race fuel and might just be adding a can now and then.
I have always been running straight 93 pump gas in this engine since I built it almost 10 yrs. ago.

FE Technical Forum / Tasca Ford KR-8 Mustang.....
« on: June 20, 2019, 10:38:15 AM »
Picture here of the supposed Loyd Ruby Ford GT-40 427 Tunnel Port engine that Ford swapped into Tasca's KR-8 1967 Mustang. Looks like those Ford only center squirt Holley carbs.
Story goes that Ford wanted to inspect Tasca's "improved" 428 and ol' Bob said he needed an engine to drive it back home with!
Bet that was a wild drive back!

FE Technical Forum / One of those 428 CJ wonders ??
« on: June 18, 2019, 06:51:24 PM »
Why didn't Ford continue with the dual Holley 4bbl. Medium Riser intake setup on the 1968 1/2 428 CJ Mustangs?
It was a well sorted out setup and multi carbs were still THE thing in late 60's! Ford had it on the 1967 GT 500 Mustangs!
Tasca's KR-8 had that setup!

FE Technical Forum / 1966 Cammer Galaxie again.....
« on: June 18, 2019, 01:54:25 PM »
Found that brief mention of the one off 427 SOHC Galaxie in one of my Ford Performance books.
If I remember I think it was reprinted from a High Performance CARS magazine of late 1966.
