There where some strength questions regarding the cast steel (not Billet) roller cam I planned to use for this build that I had sitting here for probably well over 10 years. I gave Jim my engine specs, app head flow numbers, convertor stall, and shift rpm (app 7000) and he said no issues on it no being Billet steel. He said because of the lower shift rpm if it would make me sleep better set it up for 200-220 seat and 550 open instead of the suggested 600-650. This will also let me use a hardened oil pump drive instead of bronze.
