68442CONVERTCO

Hi,



I have a 1968 442 that I am putting a 455 into. The original 400 engine stock bell housing & clutch worked just fine.

The new combination of a PRW SFI flywheel, Centerforce dual friction clutch, & Lakewood bell housing is driving me nuts trying to set up.

Using the Centerforce instructions of 4.750" for the clutch pivot ball I get the following corrected pivot ball height:

Stock flywheel deck height .960"
PRW flywheel deck height .839"
Difference from stock = .121"

Lakewood engine block plate = .139" thick

New ball stud height 4.490 = 4.750-.121-.139

Something is wrong when I hook the linkage up. I can either have the clutch release or the proper air gap of the throw out bearing. The throw outbearing is p/n 1716; I am now using a McLeod adjustable pivot ball.

Am I missing something? Maybe I should just adjust the linkage until the clutch releases, and then adjust the pivot ball height to achieve the proper bearing air gap (that will also give you the pedal free play)?

Thanks for your help in advance.

That should work..
