COMP Cams Camshaft CS 312A-R7 .900 Bc

The COMP Cams CS 312A-R7 .900 Bc camshaft is built for constant high RPM operation, making it a solid choice for oval track racing or performance builds on Chevrolet Small Block engines. This camshaft features a .900 inch lift and a 276/284 degree duration split, designed to maximize airflow and power output when the engine is running at higher revolutions per minute, especially in 358 cubic inch applications with open carburetors.

This camshaft is specifically a solid roller type, which allows for more aggressive lobe profiles and higher lift compared to hydraulic cams, contributing to its high-RPM performance. It's important to note that this camshaft is optimized for use with a Melanized or Nitrided distributor gear. Using cast or steel gears without similar surface treatments can lead to premature wear and will void all warranties. For optimal performance and longevity, ensure your distributor gear matches these specifications.

This camshaft fits a wide range of Chevrolet Gen 1 Small Block engines, including popular displacements like the 350, 400, and 327. It is not compatible with LT1/LT4 engines or factory roller small blocks from 1985 and newer. Additionally, 1955-1957 models require a specific oiling groove on the rear journal, and if your engine falls into this category, you'll need to contact us for a specific application. Always verify your engine's factory configuration, whether it's a flat tappet or factory roller, before installation.
