Hello everyone. New to the site. 1967 442. Have original 400 that needs rebuilt so going with a 455 for now. Drilled hole in crank and installed bearing. Hoping for the best! Apologies if this has been covered. I couldn't find anything searching the threads. Question is about the pressure plate and clutch. Having a hard time finding the right pressure plate / clutch on line. Have a few chevy ones laying around and they don't interchange. Correct? I'm guessing 400 and 455 would use same pressure plate. Any recommendations for pressure plate and clutch and where to find it? Thanks!

 

They mostly interchange- GM 10.5/11", 10 spline, 1 1/8 input. You may run into a (lack of) depth issue. Allstar makes extended pilot bushings.

 

Thank you for the reply! I tried a couple I had laying around. Bolt holes don't line up. I had read somewhere a chevy pressure plate wouldn't match up. Was hoping to use one i have off a BBC but no luck. So, trying to find the right one. Just not having luck pulling one up on Google.
