COMP Cams Camshaft CS XM 264HR-12

This COMP Cams Xtreme Marine camshaft is designed to give your Chevrolet Gen 1 Small Block engine a significant boost in torque and throttle response, especially at higher RPMs. You'll get the camshaft itself, which is a hydraulic roller type, ready to be installed in compatible engines. It's built to enhance your engine's performance for applications like pleasure boats, offering improved acceleration and a more engaging driving experience without excessive valve train noise.

COMP Cams engineered this camshaft with their Constant Radius of Curvature (CRC) Technology, which helps ensure durability even with aggressive hydraulic roller designs. The faster intake valve opening ramps increase engine vacuum and sharpen throttle response, while the special intake closing ramps build more cylinder pressure for better torque. On the exhaust side, smoother designs help purge spent gases more effectively, contributing to increased horsepower. This camshaft is optimized for use with a Melanized or Nitrided distributor gear, so be sure to use the correct type to avoid warranty issues.

This camshaft fits a wide range of Chevrolet Gen 1 Small Block engines, including popular displacements like the 350 and 400 cubic inch V8s, found in vehicles from AM General Hummer to Buick Roadmaster and Chevrolet Caprice. It's a solid option for those looking to extract more performance from their classic Chevy V8, particularly in marine applications where torque and responsiveness are key.
