COMP Cams Camshaft CB 290H-R10

If you're building a hot street machine for your Chevrolet Big Block, this COMP Cams Magnum hydraulic roller camshaft is a solid choice. It's designed for engines originally equipped with flat tappet camshafts, specifically the 396 to 454 cubic inch displacements. This camshaft is intended for builds that will see over 2500 RPM, requiring at least a 2500 stall torque converter and a compression ratio of 9.5:1 or higher to perform at its best.

You'll want to pair this camshaft with headers and an aluminum intake manifold to really let it breathe and achieve its potential. Expect a noticeable, rough idle with this cam, which is characteristic of performance camshafts designed for increased airflow and power. The hydraulic roller design means you get the benefits of reduced friction and wear compared to flat tappet systems, allowing for more aggressive profiles and better valvetrain stability at higher RPMs.

This camshaft fits a wide range of Chevrolet vehicles from the late 1960s through the 1970s and into the early 1980s, including popular models like the Chevrolet C10 Pickup, Camaro, and Impala. It's important to note that this camshaft is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and break-in procedures.
