What crank are you using, Notch? Is it an aftermarket steel crank, or a stock crank thats been stroked? If its stock and has flange on the end for the 2 piece rear main, it is a 28.2 oz. If it is smooth on the end, (one piece rear main) it is a 50 oz. If you go 50 you will need the Motorsport flexplate. M-6375-E302 It is the special 50 oz 157 tooth designed for C4's on late model engines.
