See, there are all kinds of conflicting information out there on this. I've read in several places that you must use a raised diaphragm clutch or you'll need a taller t/o bearing. But, there is more than one way to do this.If your Chevy clutch doesn’t have low fingers I t’s a no go for this application.
The easiest option would be to use a low throw clutch.
Edit: Nevermind, I am thinking of an LS application.
