Product Details

If you're looking to give your Cadillac's big-block V8 a serious performance boost for street driving, this COMP Cams Thumpr camshaft is a solid choice. Designed specifically for Cadillac 425, 472, and 500 cubic inch engines, this camshaft aims to deliver a noticeable improvement in power while giving you that aggressive, thumping idle sound that many enthusiasts appreciate.

This is a hydraulic flat tappet camshaft, meaning it uses a stock-style valvetrain. The grind features a 226-degree intake duration and a 241-degree exhaust duration, which is aggressive enough for a high-performance street application. While it can work with a stock torque converter, COMP Cams recommends a converter with at least a 2000 RPM stall speed and appropriate gearing to really take advantage of what this cam has to offer. You'll get an improved throttle response and a more potent powerband, especially in the mid-to-upper RPM range, all while maintaining that distinctive choppy idle.

When installing a camshaft like this, it's important to follow the manufacturer's detailed instructions. This camshaft is not CARB approved and cannot be shipped to California. Ensure your engine is clean and properly lubricated during installation to ensure longevity and optimal performance.
