COMP Cams Camshaft CS 47S 300R-6

COMP Cams has built a reputation for making serious performance engine parts, and this CS 47S 300R-6 solid roller camshaft is a prime example. If you're building a drag car or a high-performance street machine around a Chevrolet Small Block engine, this camshaft is designed to give you an edge. It features a 427 cubic inch displacement rating and a 4/7 cylinder firing order swap, which helps improve exhaust scavenging and can lead to better power delivery, especially at higher RPMs. The camshaft has a duration of 264 degrees on the intake and 270 degrees on the exhaust, with a .550 inch lift on both sides, making it suitable for aggressive racing applications.

This camshaft is specifically designed for Chevrolet GEN 1 Small Blocks, covering a wide range of displacements from 262 to 400 cubic inches. It's important to note that this camshaft is for engines originally equipped with a flat tappet camshaft. If your engine was factory-equipped with a roller camshaft (typically 1985 and newer 305s and 350s, especially in Camaros, Firebirds, and Corvettes), this camshaft will not fit without modifications. You can confirm your engine type by removing the intake or timing cover. Early 1955-1957 Chevrolet 265 engines also have specific oiling groove requirements that this particular part number does not accommodate; please contact us if you need a camshaft for those specific early models.

This camshaft is a significant upgrade for serious performance builds. It's intended for use in a variety of vehicles, including many Chevrolet, Buick, and Cadillac models from the 1980s and early 1990s. Remember that this camshaft is not CARB approved and cannot be shipped to California. For optimal performance and reliability, ensure you consult the manufacturer's installation instructions and consider pairing it with appropriate valve springs, lifters, and other valvetrain components designed for solid roller camshafts.
