I don't try to pick my own cam, I always call Scnieder cams tell em what I'm doing and what I expect and a few days latter the big brown truck shows up, never been dissapointed, figure them guy's been grinding cams a long long time and know whats up... In my younger day's on any street small block chevy ya just went to your local chevy dealer and told em ya wanted a corvette white sheet cam....
