Roller Cam LA 360

Go for it.
I've got one of those 4 inchers with indy 202 heads from IMM and a Fitech 600 @ 10.5:1. Goes like hell with the 3.23's and pitches my 68 Cuda sideways at 30 with the 3.55's. Rev limiter mandatory. Has a long power band and pulls like hell. I'm guessing it's real close to 500 will probably be more after the switch to solid roller lifters.
