Anybody use one of these in a smallbock Chevy? My buddy just bought one that I put in his '56 Chev gasser with a 350/th350. We finished the engine swap, with conversion to side mounts and tranny crossmember today, and fired it for the first time. I was surprised how radical the cam sounds. Specs don't seem to indicate it would be, but it sure has a lumpy idle, and grabs rpm's pretty fast!
