Product Details

COMP Cams is well-known for making performance camshafts that help engines breathe better and make more power. This particular camshaft, the 270H-10, is a hydraulic flat tappet design built for Cadillac engines like the 425, 472, and 500. If you're looking to give your classic Cadillac a noticeable boost in performance, especially in the mid-range RPMs, this cam is a solid option.

This cam is designed for high-performance street applications. You can expect a strong pull through the mid-range, which is great for acceleration and passing. It's recommended to pair this with an upgraded exhaust system to let the engine breathe freely, and a torque converter with a stall speed of 2000 RPM or higher to take full advantage of the cam's profile. Be aware that this camshaft will produce a choppy idle, which is a signature sound for many performance builds and lets you know the engine is working hard.

This camshaft is intended for modified applications and is not CARB approved, meaning it cannot be shipped to California. It's a direct fit for a range of Cadillac models from 1968 through 1979, including the Commercial Chassis, Calais, DeVille, and Eldorado. Ensure you have the necessary supporting modifications, like an upgraded exhaust and appropriate torque converter, to get the most out of this performance camshaft.
