I do not not if this applies to big block Chevelles but on big block Camaros there is the issue of 3 different size throw out bearings and making sure that the replacement is the same height as the one that came out originally. Also if you have the original pressure plate available compare the height. I know this because when I installed a small block in a big block car I used the 11 inch clutch set up and the trans had to come out 3 times till I got it right.
