SBF 351C Magnum Hyd. Roller Cam 284HR

The SBF 351C Magnum Hyd. Roller Cam 284HR from COMP CAMS is a high-performance hydraulic roller camshaft engineered for serious Ford Cleveland and modified engine builds. This camshaft delivers the precision timing and lift characteristics required to maximize power output in performance and racing applications where reliability and repeatability are non-negotiable. Whether you're upgrading a classic muscle car or building a competition engine, this roller cam provides the foundation for consistent, responsive power delivery across the RPM range.

The SBF 351C Magnum Hyd. Roller Cam features a 0.566-inch lift on both intake and exhaust valves with a 284-degree duration specification and a 110-degree lobe separation angle (LSA), optimized to operate between 2,000 and 5,500 RPM. The hydraulic roller design eliminates the friction and maintenance demands of flat-tappet designs while providing superior durability under high-load conditions. COMP CAMS precision engineering ensures exact specifications in every casting and ground profile, delivering repeatable performance and extended component lifespan in demanding engine environments.

This camshaft is ideal for engine builders and enthusiasts developing Ford Cleveland platforms and modified variants seeking balanced low- to mid-range torque with responsive top-end power. The 110 LSA provides good overlap characteristics for street-driven and weekend race applications. Installation should be performed by experienced engine builders who can verify proper degree timing, verify clearances with your specific cylinder head and valve train components, and confirm compatibility with your complete induction and exhaust system for optimal results.
