BBC Soild Roller Cam

The HOWARDS RACING COMPONENTS BBC Solid Roller Cam (HRC121133-14) is a mechanical roller camshaft engineered specifically for big block Chevy applications requiring a broad torque band and high RPM capability. This solid roller cam delivers 0.680 inches of lift on both intake and exhaust sides, with a 293-degree intake duration and 301-degree exhaust duration, positioned at a 110-degree lobe separation angle (LSA). The operating range spans 3400 to 7500 RPM, making it suitable for street performance builds, bracket racing, and high-output engine combinations where mechanical reliability and predictable valve timing are non-negotiable.

The symmetrical lift profile and moderate duration specifications position this cam in a sweet spot for engines seeking improved low- to mid-range responsiveness without sacrificing high-RPM power. The 110 LSA overlap configuration reduces valve overlap, enhancing idle quality and improving cylinder scavenging efficiency across the intended RPM band. Solid roller designs eliminate valve train compliance and noise associated with flat-tappet or hydraulic roller systems, translating to precise valve actuation and reduced maintenance intervals. At 11.03 lbs, this camshaft integrates into complete big block Chevy engine assemblies with standard cam bearing provisions.

Builders and engine tuners choosing a big block Chevy solid roller cam prioritize valve event consistency, mechanical durability, and the ability to maximize performance across a controlled RPM window. This HOWARDS RACING COMPONENTS profile serves applications ranging from weekend bracket racing and street/strip hybrids to dedicated track builds where predictable power delivery justifies the investment in roller lifter hardware and associated valvetrain upgrades. Proper installation requires compatible solid roller lifters, rocker arms, and pushrods; verify clearances and lobe centerline during engine assembly to achieve design intent.
