COMP Cams Camshaft CB 321QnHR-10

If you're building a serious drag racing machine with a Chevrolet Big Block engine, this COMP Cams camshaft is designed to help you get down the track faster. Specifically tuned for 454 cubic inch engines, it's best suited for builds with good cylinder heads and requires a healthy 11:1 compression ratio along with a 4500+ RPM stall speed torque converter to really shine. This hydraulic roller camshaft is engineered to work with Chevrolet GEN IV Big Block engines that originally came with flat tappet camshafts, offering an improved valvetrain setup for performance applications.

This camshaft features a 267-degree intake duration and a 275-degree exhaust duration, with a 110-degree lobe separation angle. These specs are chosen to provide a strong powerband in the upper RPM range, ideal for drag strip conditions where you need maximum output. The hydraulic roller design means less friction and more consistent performance compared to older flat tappet designs, allowing for more aggressive cam profiles and better durability. It's a well-built component that forms the heart of a high-performance engine build.

When installing this camshaft, remember that it's intended for competition use and requires supporting modifications like a high-stall torque converter and adequate compression to achieve its potential. It's a significant upgrade for drag racing enthusiasts looking to extract more power from their big block Chevrolet. Please note that this part is not CARB approved and cannot be shipped to California.
