Description
Split duration cam for light bikes with 80-88c.i. engines, with more mid and upper end power than the 3030.
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.
