If you are going to spend the money on a custom grind at very least make sure the cam you choose is based on a .904 lifter dia and not a .875 ford or .842 chevy. Hughes has .904 based grinds comp has them as well but make sure you ask for a .904 grind or you might get a chevy grind and the reason you want a .904 grind is faster cam action ie faster ramps more seat time for a given duration @ .050 than a .875 ford or .842 dia chevy it just comes down to taking advantage of the larger dia lifter and getting more bang for your buck
