Butler with 350 Chevy

[lal Naja]

I hope there are a few of you out there that have a small block Chevy in your Cobra?

I do and I have a small issue with the clutch throwout fork. It is an original Chevrolet part, but I don't remember what model or the part number. Anyway, the problem is that the fork is a little too long and it binds with the drivers side aluminum heat-shield. I'm ready to cut it down to shorten it and I thought I would ask first to see if anyone had other solutions.

I've already modified it once to accommodate a hemispherical -joint without changing the length, so doing it again is no big problem.

It would also be great to know what fork & slave cylinder you are using.

Thanks,

Arthur

Hello Arthur,
I can help you out. I suggest you look for a chebbie V6 clutch fork and use a longer stud on the pivot ball as well. Send me an email to jeffc@cobrasnvettes.com and remind me what you need. I am at home with all info you need in my shop. These are all GM part numbers so you can pick up from local suppliers.

I suggest the use of an external slave with a 1" bore and 3/4 inch M/C. It will balance very nice so a heavy pressure plate become manageable.

I had to shorten my clutch fork too. I use a Jaguar 4 speed manual with a Laycock Overdrive. string box and I had the Bellhousing custom made out of Aluminium (it was made in S.A.
My motor is a small block 400 Chevy, bored 0.030 oversize. It has Eagle 6 " ,H Beam rods with a steel crank.Main bearing studs hold the crank in. The cam is a full roller with premium Comp Cams Roller lifters and a Rev kit also installed .Full alloy roller rockers work the valves.
The cam button is also a roller bearing with torrington roller bearing behind the cam gear. This is all balanced ,including clutch and flywheel.
Edelbrock performance RPM heads with a decent amount of port work and an Edelbrock Victor Junior intake also all Port matched, and an 800 Doublepumper spreadbore Holley.
A trouble free HEI Billet distributor and steel braideed plug wires all work geat.
I regularly rev this motor to 8000rpm and it is so smooth .

Arthur,
I just came across this post and looked for your email but did not find it. I know you said you sent one but its lost, sorry if I lost it. Do you still need numbers?

[lal Naja]

Hi Jeff, Yes I would appreciate part numbers for the clutch fork that will be shorter than the one I selected.

Currently I'm using a 14048868 fork arm. 908404 bearing, 14060624 & 14085535 Clutch & pressure plate. This is in a Mcleod 8610 bell housing.

Thanks,

Arthur
