I don't have direct experience with that cam which I believe is a Crower offering. I've had the comp 280h, which has .020 additional lift and is advertised at 230 degrees @.050 on both the intake and exhaust lobe. In a 455 the cam made lots of low end with some good mid-range grunt, but was done by about 4800 rpm.
