BBC Solid Roller Cam 306BR-10

The COMP Cams BBC Solid Roller Cam 306BR-10 is a purpose-built mechanical component engineered for big-block Chevrolet engines demanding maximum performance and reliability in high-RPM applications. This solid roller design eliminates the wear and maintenance concerns of traditional flat-tappet cams while delivering the consistent, repeatable valve actuation critical for serious engine builders and competitive racing platforms. Whether you're assembling a street-strip hybrid or a dedicated race engine, this cam provides the mechanical foundation for aggressive valve timing and lift profiles.

Solid roller cam technology uses hardened steel roller lifters that ride directly on the cam lobe, reducing friction and eliminating the scuffing and accelerated wear inherent in flat-tappet designs. The 306BR-10 designation indicates a specific lift and duration profile optimized for BBC (big-block Chevrolet) architecture, delivering precise valve event timing that works seamlessly with modern fuel injection or traditional carbureted setups. The solid construction and roller design allow this cam to operate at higher RPMs with greater safety margins, making it ideal for engines routinely spinning past 6,500 RPM and into the 7,000+ range. COMP Cams' manufacturing precision ensures tight tolerances and consistent lobe geometry across the entire component.

Experienced mechanics and engine builders select the BBC Solid Roller Cam 306BR-10 when building or rebuilding big-block Chevrolet engines for drag racing, road course competition, or high-performance street applications where reliability and repeatability cannot be compromised. Installation requires a compatible roller lifter set, adjustable pushrods, and proper clearancing of the block's lifter valley—tasks best handled by shops with BBC experience. This cam pairs effectively with performance cylinder heads, aggressive intake manifolds, and tuned exhaust systems to unlock the true potential of your big-block platform.
