Cam, Converter, Gear?

74Swangur,
DON'T use the .509 as it has too much overlap for the 383 and the short stroke, IMO you would be better off with the .474 cam or the like from comp cams. Something in the extreme energy line, try to keep the duration to less than 230 @ .050 for the converter used and you'll be alot happier with the gear and parts stated.
