I just put a new Centerforce 2 clutch behind my fresh 292 in a '68 Chevy C/10. The clutch doesn't disengage the trans from the engine. It won't shift right. I use the same geometry as the old stock clutch linkage. Some components were replaced but the original dimensions were preserved. A machinist suggested a taller bellhousing pivot ball -- but I'd still need to pull the SM465 4-speed to get at this piece w/a 3/8" allen key.
Could I have the wrong Throw-out bearing? I'm using the shorter one. I thought that was correct.
We had a similar problem when we put a Centerforce 2 clutch behind a V8 350 in my '71 GMC 4x4, a few years back. We wound up adding about 5" to the clutch push rod (lower) and joggling the ears of the Z-bar to clear hedders.
Anyone else had similar problems?
