Sbc Billet Cam Cs-300br-6 Solid Roller

The COMP Cams SBC Billet Cam CS-300BR-6 Solid Roller is a purpose-built mechanical roller camshaft engineered specifically for small-block Chevy drag racing applications. This solid roller cam delivers the aggressive valve event timing and lift required for high-RPM drag strip performance, combining a 300-degree intake and 308-degree exhaust duration with a 106-degree lobe separation angle to maximize power in the 4200 to 7200 RPM operating window.

The camshaft's 0.630-inch lift on both intake and exhaust lobes provides the valve opening height needed for efficient fuel-air mixture exchange at drag race speeds. The 106 LSA configuration balances intake opening and exhaust closing characteristics to optimize cylinder filling and scavenging in naturally aspirated small-block Chevy engines. Solid roller cam technology eliminates valve lash variability and offers precise, repeatable timing across throttle cycles—critical for consistent quarter-mile performance. The billet construction ensures durability under the extreme valve spring pressures typical of drag racing powerplants.

This cam is designed for dedicated drag racing engines where maximum power output within a narrow RPM band takes priority over street drivability or idle quality. Serious small-block Chevy racers building fuel-only or gasoline drag race engines will find the CS-300BR-6 addresses the specific timing and lift requirements of competition-level small-block applications. COMP Cams' reputation for precision manufacturing ensures reliable performance at high RPM and under sustained boost or nitrous conditions common in organized drag racing.
