COMP Cams Camshaft CS 288A-R6

This is the COMP Cams CS 288A-R6 Solid Roller Camshaft, part number 12-900-9. It's built for Chevrolet Small Block engines, specifically those that use a flat tappet camshaft setup and are not factory roller blocks from 1985 or newer. This camshaft is a popular choice for heavy cars and smaller displacement engines used in puller, mud, oval track, and drag racing applications where maximum torque is a priority. It's designed to work well with a 10:1 or higher compression ratio and typically pairs with a 3500+ RPM stall torque converter.

The CS 288A-R6 features a 252 degrees of intake duration and 258 degrees of exhaust duration, making it a solid performer for its intended use. A critical point for installation is that this camshaft is optimized for use with a Melanized or Nitrided distributor gear. Using a cast iron or steel gear without a similar surface treatment will void all warranties and return policies, so be sure to select the correct distributor gear to match. This camshaft is best suited for 350-370 cubic inch engines needing strong low-end torque.

It's important to verify your engine's configuration before ordering. While many Chevrolet Small Blocks from 1980 through the mid-1990s use a flat tappet camshaft, some models, particularly performance variants and later production vehicles, may have come factory-equipped with roller camshafts. Removing the intake manifold or timing cover is the surest way to confirm your block's setup. Additionally, 1955-1957 Chevrolet 265 engines require a specific oiling groove on the rear journal, which this particular camshaft does not accommodate; please contact us if your application requires that specific feature.
