COMP Cams Camshaft CS 299T HR-107 BMT T

COMP Cams is well-known for making performance valvetrain components, and their Big Mutha' Thumpr line is designed for serious power. This CS 299T HR-107 camshaft is a hydraulic roller grind built for Chevrolet Small Block engines, specifically targeting street/strip applications where a rough idle and aggressive powerband are desired. It’s a popular choice for enthusiasts looking to significantly change their engine’s character and performance.

This camshaft features a 243-degree intake duration and 257-degree exhaust duration at .050 lift, with a 107-degree lobe separation angle. To get the most out of this grind, you'll need at least 9.5:1 compression, a torque converter with a 2800+ RPM stall speed, an upgraded intake manifold, and headers. It's important to note that this camshaft is optimized for use with a melanized or nitrided distributor gear; using a cast or steel gear without similar surface treatments will void the warranty. This camshaft fits a wide range of Chevrolet Small Block engines, including popular models like the Camaro, Corvette, and C10 trucks from 1980-1996, but be sure to check your specific block for factory roller vs. flat tappet compatibility, as GM transitioned gradually.

When installing this camshaft, remember that it's designed for a very rough idle and significant performance gains. Ensure your engine is set up with the necessary supporting modifications to handle the increased airflow and demands. This camshaft is not CARB approved and cannot be shipped to California.
