Product Details
This COMP Cams CS 310B-4 camshaft is a solid flat tappet grind designed for Chevrolet Small Block engines, specifically those with 350 cubic inches and up, running 12:1 or higher compression ratios. It's intended for drag racing applications in lighter vehicles, paired with a torque converter rated for 5000+ RPM stall speed. This camshaft is built for performance in demanding setups.
The CS 310B-4 features a 275/283 degree duration at .050 inch lift, making it a potent choice for maximizing power in your build. It's important to note that this camshaft is designed for engines with a flat tappet valvetrain. Some earlier Chevrolet Small Blocks, particularly 1955-1957 models, have an oiling groove in the rear journal that this specific part number does not accommodate. Always verify your engine's configuration before installation.
This camshaft fits a wide range of Chevrolet GEN 1 Small Blocks, including popular displacements like the 262, 283, 305, 327, 350, and 400 cubic inch engines. It is not compatible with LT1/LT4 engines or factory roller small blocks from 1985 and newer. For those with specific early engine configurations or questions about fitment, consulting with a specialist is recommended.
