About this part

Product Details

COMP Cams is well-known for making performance engine parts that help you get the most out of your vehicle. This Big Mutha' Thumpr camshaft is designed for enthusiasts looking to build a powerful street/strip engine for a wide range of classic Chevrolet and Buick vehicles. It's a hydraulic roller camshaft that works with factory roller setups on Small Block Chevy engines from 1987 and newer.

This camshaft features a 243-degree intake duration and a 257-degree exhaust duration, with a 107-degree lobe separation angle. To make this camshaft perform its best, you'll need a solid foundation. COMP Cams recommends a minimum of 9.5:1 compression ratio, a torque converter with at least a 2800 RPM stall speed, and supporting modifications like an upgraded intake manifold, rear gears, and headers. Expect a very rough idle with this aggressive camshaft profile, which is characteristic of its performance intent.

This camshaft is intended for modified engines and requires careful consideration of supporting components to achieve optimal performance and reliability. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for specific details regarding setup and compatibility with your engine build.
