COMP Cams Camshaft CS 285Jfa S7 Modifie

Starting with a 256-degree intake and 260-degree exhaust duration, this COMP Cams camshaft is built for modified engines, particularly in open-wheel racing applications where controlling tire spin is key. It's designed for engines with 355 cubic inches or larger, a 12:1 compression ratio, and a 4-barrel carburetor running on gasoline or alcohol, provided you have good intake and cylinder heads to support it. This camshaft is part of the OWM T/C Series, which COMP Cams developed to offer a broad torque curve and strong power while helping to reduce excessive tire spin, acting as a form of legal traction control for racers.

This camshaft utilizes a solid flat tappet design, making it a great choice for racers whose sanctioning body requires this type of valvetrain and whose engine combination can handle high rocker arm ratios. COMP Cams has engineered these lobes with updated technology to bring camshaft performance for modified racers into the next century. For optimal performance and longevity, COMP Cams recommends using premium-quality valve springs, lifters, and pushrods with this camshaft.

This camshaft fits a wide range of Chevrolet GEN 1 Small Block engines, including popular displacements like the 350 and 400 cubic inch V8s found in vehicles such as the Chevrolet C10, Camaro, and Caprice. It's important to verify your engine uses a flat tappet valvetrain, as many later model Small Blocks (especially from 1985 and newer) came factory-equipped with roller camshafts. You may need to remove the intake manifold or timing cover to confirm which type of valvetrain your engine has.
