OK, so I'm really confused at this point. I was going to swap in a used 307 I had lying around, but changed my mind and went with a new 350 crate engine. I had purchased a complete clutch kit for a 71 C10 that the 307 was out of. I assumed that it would work fine with the 350. Here is my problem:

When I measure the thickness of the 3 pressure plates, they stack up like this:

Factory 307 - shortest of all of them
Factory 292 - thicker than the 307 but shorter than the new clutch
New Replacement (71 C10 307 bent finger) - Fattest of all of them

The new throwout bearing is the same height as the one out of the 307. The 292 throwout bearing is much taller.

I am reusing the bell housing, fork, flywheel and linkage from the 292. Should I have purchased a clutch kit for a 1966 292 and just used that on the new crate motor? Or is there another clutch kit I should be using?

Thanks!
