This kit is specifically designed for Chevrolet Big Block engines, including the popular 396, 427, and 454 cubic inch displacements. If you're looking to give your classic muscle car a serious attitude and improved performance, this camshaft is a solid choice.

This CB 295T H-107 BM camshaft features a 243-degree intake and 257-degree exhaust duration, which is tuned to work best with a street/strip setup. To get the most out of this cam, you'll need at least 9.5:1 compression, a torque converter with a stall speed of 2800 RPM or higher, and you should plan on using a performance intake manifold, appropriate gearing, and headers. Expect a very rough idle with this cam; it's meant to be heard and felt, signaling serious performance intent. This kit is designed to fit a wide range of Chevrolet vehicles from the mid-60s through the mid-90s, including popular models like the Chevrolet C10 Pickup, Chevrolet Impala, and Chevrolet Camaro.

When installing this camshaft, remember that it's intended for off-road use and is not CARB approved, meaning it cannot be shipped to California. Ensure you have all the necessary supporting components like the intake, headers, and a suitable torque converter to match the cam's aggressive profile. This kit is a significant upgrade for anyone building a performance-oriented Big Block Chevrolet.
