Product Details

This is the COMP Cams CB 322A-R12 solid roller camshaft, built for serious drag racing applications on Chevrolet Big Block engines. If you're working on a 396, 427, 454, or even a larger 500+ cubic inch engine and aiming for serious performance, this camshaft is designed to help you achieve it. It's specifically intended for tunnel ram setups and requires a high-stall torque converter (5500+ RPM) or a manual transmission to make the most of its aggressive profile.

The CB 322A-R12 features a 282-degree intake duration and a 298-degree exhaust duration, with a solid roller lifter design. This means it's built for high RPM operation and durability under stress. It's a direct replacement for engines originally equipped with flat tappet camshafts, but you'll need to ensure you have the correct supporting components, including roller lifters, roller rocker arms, and appropriate valve springs, to handle the increased lift and duration. This camshaft is intended for bracket racing and similar performance-oriented events where consistent power delivery at high RPMs is key.

This camshaft fits a wide range of Chevrolet vehicles from the late 1960s through the early 1990s, including popular models like the Chevrolet Chevelle, Camaro, Corvette, Impala, and C10 Pickup. Remember that this camshaft is not CARB approved and cannot be shipped to California. Always consult the manufacturer's installation instructions for proper setup and to ensure you have all necessary components for a successful build.
