COMP Cams Camshaft CS 308A-R7

If you're building a performance Chevrolet Small Block engine for oval track racing or demanding road course applications, this COMP Cams CS 308A-R7OT solid roller camshaft is designed to give you a serious edge. It's optimized for engines making around 311-355 cubic inches with an open carburetor setup, offering strong performance where it counts. This camshaft is a popular choice for racers looking to extract maximum power from their Gen 1 Small Block Chevy.

This camshaft features a 272 degrees intake duration and 274 degrees exhaust duration with a .050 lift, making it a solid roller design for improved valve lift and faster ramp speeds compared to flat tappet cams. For optimal performance and to ensure longevity, it's crucial to use a Melanized or Nitrided distributor gear with this camshaft. Using cast iron or steel gears without these surface treatments can lead to premature wear and will void the warranty.

COMP Cams has engineered this camshaft to fit a wide range of Chevrolet Gen 1 Small Block engines, including popular displacements like the 350, 400, and 327. It's important to verify your specific engine's configuration, as some factory roller blocks from 1985 and newer, or specific early models like the 1955-1957 265ci engines with an oiling groove, may require different setups or further compatibility checks. Always refer to the manufacturer's detailed fitment notes and installation instructions to ensure proper application and to avoid potential issues.
