COMP Cams Camshaft CB 280H-R10

If you're building a street machine and want a noticeable rumble and improved performance from your Chevrolet Big Block engine, this COMP Cams Magnum camshaft is a solid option. This is a hydraulic roller camshaft, which means it uses roller lifters to reduce friction and wear compared to traditional flat tappet designs. It's designed for engines originally equipped with flat tappet camshafts, offering a significant upgrade in performance and durability.

This camshaft features a 224-degree intake and 224-degree exhaust duration at .050 lift, with a .552-inch intake and .552-inch exhaust lift. It's intended for use with headers, a compression ratio of 9.5:1 or higher, and a torque converter with at least a 2000 RPM stall speed. You'll also want to consider lower gears in your rear end to take full advantage of the powerband this cam unlocks. Expect a rough idle, which is characteristic of performance cams like this, but it translates to a more aggressive sound and better breathing for your engine.

This camshaft fits a wide range of Chevrolet vehicles from the late 1960s through the mid-1990s, including popular models like the Chevrolet C10 Pickup, Chevrolet Impala, and Chevrolet Camaro. 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 necessary supporting modifications, such as appropriate valve springs and pushrods, to get the most out of this performance camshaft.
