BBC Solid Roller Cam CB 300BR-14

The BBC Solid Roller Cam CB 300BR-14 from COMP CAMS is a purpose-built roller camshaft engineered for big-block Chevrolet engines demanding aggressive valve timing and maximum lift characteristics. This solid roller design is the choice for serious engine builders and racers who require repeatable, high-RPM performance without the maintenance concerns of hydraulic lifters. Whether you're building a street strip machine, drag racing engine, or high-output street performance application, this camshaft delivers the valve actuation curve needed to extract power from larger displacement platforms.

Solid roller cam technology eliminates deflection and ensures precise valve timing across the entire RPM band, critical when running elevated spring pressures and aggressive valve overlap. The CB 300BR-14 designation indicates a solid roller design with specific lobe profiles optimized for BBC applications, delivering consistent lift and duration that hydraulic designs cannot match at high RPM. COMP CAMS' manufacturing process ensures concentricity and lobe geometry within tight tolerances, allowing the cam to work harmoniously with roller lifters that reduce parasitic losses and provide superior durability. The 10.53 lb mass is typical for BBC solid roller cams, reflecting the material density required for durability under sustained high-load conditions.

Installation requires a compatible roller lifter set, solid roller timing chain, and properly degreased lifter bores to prevent premature wear. This camshaft is ideal for BBC engine platforms including 427, 454, and 496 displacement combinations where consistent valve control translates directly to horsepower gains and reliability. Verify your engine block and cylinder head are prepared for solid roller lifter geometry, and confirm spring installed height to ensure proper valve train geometry. Professional installation and valvetrain validation are strongly recommended to maximize performance and longevity.
