Summit Racing™ Pro LS Automotive cams are affordable and designed in stages with very specific cam timing for each individual application in cathedral and rectangle port versions. This ensures maximum performance and gives you the idle you are looking for. The lobes are designed for stability at high rpm with the spring pressures found in quality .600 and .670 in. spring packs. Careful design guarantees the cams can be installed with minimal difficulty. Although piston to valve clearance should always be verified, the Stage 2 and 3 cams often allow for additional cylinder head milling. The Stage 4 cams often require no changes but can be degreed slightly different as needed. Starting with American bearing steel, they are precision machined on a Landis 3LB CNC grinder with CBN diamond wheels for unmatched quality.
