COMP Cams Camshaft CB 47S 314Rxh-15

COMP Cams has built a reputation for making serious performance parts for racers and hot rodders. This camshaft, the CB 47S 314Rxh-15, is a prime example of their commitment to the drag strip. It's a solid roller camshaft specifically designed for Chevrolet Big Block engines, like the 396, 427, 454, and even larger displacements, originally equipped with flat tappet cams. This isn't a mild upgrade; it's built for serious competition, featuring a 4/7 swap firing order to help smooth out the power delivery and reduce crankshaft stress during high-RPM runs.

With a duration of 281 degrees on the intake and 300 degrees on the exhaust at .050 lift, this cam offers a significant performance bump over stock. The solid roller design means less friction and more lift potential compared to hydraulic or flat tappet cams, translating to better airflow and more power. This camshaft fits a wide range of Chevrolet vehicles, including popular models like the 1967-1975 Chevrolet Bel Air, 1967-1972 Chevrolet Camaro, and 1967-1974 Chevrolet Corvette, among many others. It's intended for engines originally equipped with flat tappet camshafts, so be sure to check your specific application.

Because this is a solid roller camshaft, you'll need to ensure you have the correct valve train components to match, including roller lifters, roller rocker arms, and potentially upgraded valve springs. It's also important to note that this camshaft is not CARB approved and cannot be shipped to California. For those building a dedicated drag car or a powerful street/strip machine, this COMP Cams camshaft is a well-built component designed to put you ahead of the competition.
