FE Technical Forum / 427 Hydraulic Lifter cam C8AX-C
« on: September 18, 2026, 11:55:48 AM »
I think this cam was used on the Cougar '68 427s. 
Is it much of a step up from the CJ cam C60Z-B?
I haven't seen much about it.

FE Technical Forum / Re: #13001 Intake adaptors
« on: September 02, 2026, 10:22:32 PM »
I know it can be done that way but I'm not looking forward to it.  I have no idea where to make the cuts so it will be a slow process.

I need an Edelbrock Torker cut to fit your #13001. Do you still do that?

I feel our pain.  I'll be 81 later this month and cannot do many of the things that were routine a couple of years ago.

It would be helpful if you could post before and after pictures and flow numbers of manifolds that you have ported if you have them.  Any hints you could ad would be nice also.
 
I know we couldn't expect to get your results but it would give us a goal.

Yes they are both 13001s.  One is still in the original box. 
The Offy tunnel ram has both tops, a 2x4 and a single 4 bbl for the standard Holley 4150/4160 carbs.  It was the Offy tunnel ram Jay's used in his adapter testing.

I have on of Jay's adapter and an Offy tunnel ram. The tunnel ram is for sale on Facebook.  The adapter may be as I have two of them but my son may not let be sell it at this time.

Non-FE Discussion Forum / Modifying a 351 Cleveland intake manifold for use with Jay's adapter
« on: June 22, 2026, 10:29:34 AM »
Does modifying a manifold for use with Jay's adapter prevent the use of the manifold on a 351C engine?  I want to sell a Offenhauser tunnel ram that has been modified but I don't want mislead the buyer.

The Yukon is more than I want to spend.  And I was hoping to avoid cost of setting the ring and pinion.  The Eaton Truetrac may be what I get.

Thanks for all of the replies.  I will check out the Yukon Grizzly.

Non-FE Discussion Forum / F-250 locking differential
« on: June 16, 2026, 02:47:39 PM »
I'm tired of my 2000 F-250 having a one wheel drive.  I looked at my door tag and the axle code is blank but I only have a 5.4 engine so I guess the axle is a Ford 10.25. 

Summit has a PowerTrax Right-Lock for a Ford 10.25.  The description says installation can be done with common hand tools so I think I can just take the old spider and and install the PowerTrax - I don't have to worry about ring and pinion clearance if put every back correctly.

How do I tell if my differential is actually a Ford 10.25?

FE Technical Forum / Re: Over boring a 330FT block
« on: June 02, 2026, 08:50:11 PM »
My block is dated Jan 16 1970 and doesn't have the ribs. 

The drill bit barely goes in near the center and won't move up and down more than an inch. 

It has the reinforced mains.

I agree about the thicker wall.  And the sonic check before boring.

I thought and 1/8th inch wall would be more than enough.  Probably use a 4.13 bore so it could be overbored later.

FE Technical Forum / BBM heads from 2019
« on: June 01, 2026, 11:26:55 PM »
I have a set of BBM heads from around the 2019 time frame with 2.19 intake and 1.68 exhaust valves.

Will these heads work with a 390 block or a 428 block?

FE Technical Forum / Over boring a 330FT block
« on: June 01, 2026, 11:22:59 PM »
The following is based on a 15/64 drill bit test on 330 FT block:                       
4.63 bore spacing.  Subtract the drill bit diameter, 0.219, leaves 4.411 inches.                     
Allowing (subtracting) for two 1/8th inch (0.125”) cylinder walls leaves 4.161.                       
This is just over a 0.030 over bored 428 cylinder.  The 428 has a 4.13 bore; with a 0.030 over bore the bore is 4.16.                       
So if there isn’t much core shift I should be able to bore this block to use 428 pistons.                     

Or am I mssing something?
