COMP Cams Camshaft CS 300A-R6 .900 Bc

This COMP Cams CS 300A-R6 camshaft features a solid roller design with a .900 inch lobe lift, making it a strong choice for Chevrolet Small Block Gen 1 engines. It's specifically tuned for oval track racing, offering a 264/267 degree intake/exhaust duration split. This camshaft is designed to work with a wide range of Chevrolet Small Block displacements, from the 262 all the way up to the 400 cubic inch engines, and fits many GM vehicles from the 1980s and early 1990s, including models like the Chevrolet C1500, Camaro, and Buick Roadmaster.

The solid roller valvetrain is known for its ability to handle higher RPMs and more aggressive cam profiles compared to flat tappet designs. This particular camshaft is built with a .900 inch lobe lift, which, combined with its duration, helps to improve airflow into and out of the cylinders, leading to better power output, especially in demanding racing conditions. It's important to note that this camshaft is not compatible with factory roller camshaft blocks from 1985 and newer, nor is it designed for LS-based engines. For 1955-1957 Chevrolet 265 engines, a specific oiling groove is required on the rear journal, and this particular part number does not include it.

When installing this camshaft, ensure your engine block is set up for a solid roller valvetrain. This typically involves using roller lifters, roller rocker arms, and appropriate pushrods. Because this is a performance camshaft designed for racing, it's crucial to pair it with other components that can handle the increased stress and performance gains, such as upgraded valve springs and retainers. Always refer to the manufacturer's installation instructions for detailed guidance on proper setup and break-in procedures to ensure optimal performance and longevity.
