Crower 271HDP. 222/234@.050 .496/486 lift in 112's in at 107. run the 3.23's and you'll be fine with just a standard 383 converter. If you had more compression or 915 closed chamber heads get it cut on 108 centers.

Crabman (David K's) cam also is a great cam for the $$$, it's the old General Kinetics grind that PAW also sells as their House grind, it's very close to the Crower in duration but has a little less lift. The Crower 271 is one of those Natural cams that just does everything great.

383's love to rev but the trick is to not kill the bottom end, it has to be cammed more like you would a smallblock.

This is an AWESOME cam, maybe the best all-around BBM hydraulic cam ever made. It's also a great stock replacement cam for a 440 six pack or magnum.
