COMP Cams Camshaft CS XM 270H-12

COMP Cams is well-known for making performance parts for a wide range of engines, and this Xtreme Marine camshaft is a solid choice for anyone looking to get more out of their Chevrolet Small Block. This is a hydraulic flat tappet camshaft designed for engines from 1958 through 1998, covering displacements from 262 up to 400 cubic inches. It's built to give you a strong mid-range pull and noticeably improved throttle response, especially in applications like jet boats with an 'A' impeller, while still providing a noticeable idle.

The grind on this camshaft, with its 226 degrees of intake duration and 236 degrees of exhaust duration at .050 lift, is specifically tuned for that strong mid-range performance. It's a hydraulic flat tappet design, meaning it uses lifters that don't require any special valvetrain setup beyond what a stock flat tappet engine would have. This camshaft fits a wide variety of Chevrolet Gen 1 Small Blocks, including popular engines like the 350, 400, and 327, and also fits many GM vehicles from AM General Hummer to Buick Roadmaster and Chevrolet Caprice. Just be sure to check if your specific engine uses a factory roller camshaft, as this flat tappet design is not compatible with those.
