COMP Cams Camshaft CBVI 312Ar-10

This COMP Cams CBVI 312Ar-10 camshaft features a 276-degree intake duration and 280-degree exhaust duration, making it a solid choice for performance builds. It's a mechanical roller camshaft, which is known for its durability and ability to handle higher lift and RPMs compared to hydraulic rollers. This specific grind is well-suited for drag racing applications, particularly in Super Street or Super Gas classes where consistent performance is key.

Designed for Chevrolet Big Block GEN VI engines, this camshaft is engineered to work with a 4500+ stall torque converter. This pairing is crucial for drag racing, as it allows the engine to reach its optimal power band before the vehicle fully engages, leading to better launches and acceleration. The mechanical roller design means you'll need to ensure proper valvetrain setup, including adjustable rocker arms and potentially upgraded valve springs, to match the cam's aggressive profile. It’s a popular option for those looking to extract maximum performance from their Big Block for competitive use.

This camshaft fits a range of Chevrolet and GMC trucks and vans from the mid-to-late 1990s, including models like the C2500 Suburban, C3500, and Express 3500. While it's built for serious performance, remember that it is not CARB approved and cannot be shipped to California. Always consult the manufacturer's installation instructions for proper setup and break-in procedures to ensure optimal performance and longevity.
