Summit Racing SUM-8709: Summit Racing Pro LS Automotive Camshafts

The lobes are designed for stability at high rpm with the spring pressures found in quality .600 and .670 in. spring packs. Careful design insures the cams can be installed with minimal difficulty. Although piston to valve clearance should always be verified, the stage two and three cams often allow for additional cylinder head milling. The stage four cams often require no changes, but can be degreed in slightly differently as needed. Starting with American bearing steel, they are precision machined on a Landis 3LB CNC grinder with CBN diamond wheels for unmatched quality.
