COMP Cams Camshaft CS 291Crl R7 Open Mo

COMP Cams has a solid reputation for building performance engine components, and this solid roller camshaft is a great example of their work. This particular camshaft, the CS 291Crl R7 Open Mo, is designed for specific applications like Open Wheel Modified Traction Control setups, especially those running on 3/8-5/8 tracks with wide corners or slick surfaces. It's intended for engines with a 355 cubic inch displacement or larger, a 12:1 compression ratio, and a 4-barrel carburetor running on gas or alcohol, paired with a good intake manifold and cylinder heads.

This camshaft is built for flat tappet-appearing Beehive valve springs, which helps with valve train stability. It's important to note that while it fits a wide range of Chevrolet Gen 1 Small Blocks, including popular ones like the 350 and 400, it does not fit factory roller small blocks from 1985 and newer, nor does it fit any LS-based engines. You'll need to check your specific engine to confirm if it uses a flat tappet or factory roller setup, often by removing the intake or timing cover.
