Odiedj8, are you referring to the Comp Cam C60-280H-10 with 230/230 degrees duration at 0.050 lift? If so, this is too hot for a engine with good low end power.

For mid-range power in the 2000 to 5500/6000 rpm band, look for a camshaft with around 204 to 214 degrees duration at 0.050 lift. For more low end power below 2000 rpm, look at camshafts with 192 to 200 degrees duration at 0.050 lift.

See the table of different camshafts at the following location on this website (not a valid 'clickable' link):
