COMP Cams Camshaft CB 47S 312-R10

This COMP Cams CB 47S 312-R10 solid roller camshaft is designed for Chevrolet Big Block engines, specifically the 396 to 454 cubic inch displacements. You'll receive the camshaft itself, ready for installation into your engine build. This camshaft is intended for drag racing applications where maximum performance is the goal, requiring good cylinder heads and a compression ratio of 11:1 or higher, along with a 4500-5000 RPM stall speed torque converter.

The camshaft features a 278 degrees intake and 280 degrees exhaust duration at .050 inch lift, with a 112-degree lobe separation angle. Its solid roller design means it uses roller lifters and rocker arms, which reduce friction and allow for more aggressive cam profiles compared to flat tappet designs. This particular grind is a 4/7 swap camshaft, which helps to improve exhaust scavenging and can lead to a smoother idle and better overall performance in certain engine configurations. It's built to handle the demands of high-RPM operation common in drag racing.

This camshaft is a solid option for bracket racing and other performance-oriented builds. It's important to note that this camshaft is not CARB approved and cannot be shipped to California. Ensure your engine is set up with the appropriate supporting modifications, such as a strong valvetrain and adequate fuel delivery, to take full advantage of this camshaft's capabilities.
