BBC Solid Roller Cam 306BR-10

The COMP Cams BBC Solid Roller Cam 306BR-10 is a purpose-built mechanical roller camshaft engineered for big block Chevy drag racing engines. This 306-degree duration cam delivers aggressive valve timing optimized for high-rpm power delivery across a 4800 to 7200 rpm operating range, making it a proven choice for dedicated bracket racing and competition applications where every tenth of a second counts.

The camshaft specification reflects its drag-focused design: 0.714-inch intake lift paired with 0.710-inch exhaust lift creates the asymmetrical lift profile required for efficient scavenging at peak rpm levels. The 110-degree lobe separation angle optimizes overlap and cylinder charge control for maximized power in the narrow rpm band where drag racing engines operate. As a solid roller design, this cam eliminates the compliance and wear characteristics of hydraulic followers, delivering precise, repeatable valve events shot after shot down the track. The solid construction also enables higher spring pressures and more aggressive duration profiles than comparable hydraulic roller camshafts.

Drag racers and bracket racing competitors building big block Chevy combinations depend on COMP Cams' roller cam specifications to achieve consistent cylinder head scavenging and predictable power delivery. This profile suits engines built for heads-up competition where repeatability and peak-rpm power are non-negotiable. The 306-degree duration strikes a balance between aggressive timing and practicality for solid roller conversion builds that retain adequate idle quality and part-throttle manageability outside of racing trim.
