Description

Race idle, Pro Street. Needs increased compression and 3500+ stall. Limited street use.

COMP Cams Magnum cams have great high rpm power, are easy on valve train parts, and can be used with mild ratio rocker arms and traditional performance valve springs. They really need converter and gear changes, these like compression (9.5:1 and up), and larger magnums are a little lazy at low rpm.
