COMP Cams Camshaft CB 47S 310Rxd-14

This COMP Cams camshaft features a 277/292 degree duration split with a 0.620 inch lift on both intake and exhaust, utilizing a solid roller design. It's specifically built for Chevrolet Big Block engines from 396 to 454 cubic inches, originally equipped with flat tappet camshafts. The 4/7 swap firing order is a notable design choice that helps improve exhaust scavenging and can lead to a more stable idle and better overall engine response, especially in drag racing applications.

Constructed with a solid roller valvetrain, this camshaft is designed for high-RPM performance and reduced friction compared to flat tappet designs. The aggressive lift and duration figures are intended to maximize airflow through the engine, making it a strong choice for drag racing builds where every bit of power counts. It's important to note that this camshaft is not CARB approved and cannot be shipped to California. Also, be aware that 1965-1966 396 cubic inch Big Blocks with an oiling groove in the rear journal are not compatible with this specific part number; please contact us if you require a camshaft for those specific models.

When installing a camshaft of this caliber, ensure your valvetrain components, including lifters, pushrods, and valve springs, are compatible with the camshaft's specifications to achieve optimal performance and reliability. Proper break-in procedures are also critical for the longevity of a solid roller camshaft.
