COMP Cams Camshaft CS 316A-R8

If you're building a drag-focused Chevrolet Small Block engine and looking for a solid roller camshaft that can handle serious abuse, the COMP Cams CS 316A-R8 is a popular choice. This camshaft is designed for performance applications, featuring a 280-degree intake and 288-degree exhaust duration at .050 lift, with a .550 lift on both intake and exhaust. It's built to work with a Melanized or Nitrided distributor gear, which is crucial for longevity and warranty compliance. Using cast or steel gears without these surface treatments can lead to premature wear and void your warranty.

This camshaft fits a wide range of Chevrolet Gen 1 Small Block engines, including popular displacements like the 350, 400, and 327. However, it's important to note that it does not fit factory roller blocks from 1985 and newer, nor does it fit LT1/LT4 or LS-based engines. For 1955-1957 models, a specific oiling groove is required on the rear journal; if your block needs this, you'll need to contact us for a special order. This camshaft is optimized for performance builds where maximum power and durability are key.

When installing this camshaft, ensure you use the correct distributor gear as specified by COMP Cams. This is a critical step to ensure the camshaft performs as intended and to maintain your warranty. If you're unsure about your block's factory configuration or distributor gear type, it's always best to remove the intake or timing cover for a visual inspection before ordering.
