COMP Cams Camshaft CB 47S 314Rxd-14

This COMP Cams camshaft features a 281/296 degree duration at 0.050 inch lift and a 0.630 inch lift for both intake and exhaust. It’s a solid roller camshaft designed for Chevrolet Big Block engines, specifically for drag racing applications. The 4/7 swap design is a notable feature that helps improve cylinder scavenging and overall engine breathing, which is crucial for maximizing power output on the track. This camshaft is intended for engines originally equipped with flat tappet camshafts, and it’s important to note that it is not compatible with 1965-66 396 c.i.d. models that have an oiling groove in the rear journal.

Built for performance, this camshaft utilizes a solid roller valvetrain, which allows for higher lift and more aggressive profiles compared to hydraulic or flat tappet designs. This translates to better airflow and more power, especially at higher RPMs. The specific lift and duration numbers are chosen to provide a strong powerband suitable for drag racing, where quick acceleration and peak horsepower are key. Ensure you have the appropriate supporting components, such as roller lifters, roller rockers, and a compatible valvetrain geometry, to take full advantage of this camshaft's capabilities.

This camshaft fits a wide range of Chevrolet vehicles with Big Block engines, including models like the Chevrolet Impala, Chevelle, and Camaro from the late 1960s through the mid-1970s, as well as many C/K series trucks. When installing, it's essential to follow the manufacturer's recommended break-in procedure for solid roller camshafts to ensure proper lubrication and wear-in of the roller components. This process is critical for the longevity of the camshaft and the engine.
