CompCams High Magnum Camsafts are great for high rpm power. Magnum cams are easy on valve train parts. Can be used with mild ratio rocker arms and traditional performance valve springs. Really need converter and gear change. These like compression (9.5:1 & up). Larger Magnums are a little lazy at low rpm.
