Product Details

This is the COMP Cams Xtreme Marine 212/218 hydraulic roller camshaft, part number 08-416-8. It's built for Small Block Chevrolet (SBC) engines that came with factory roller camshafts, specifically the Gen 1 Small Blocks from '87 onwards, excluding LT-1 and LS1 variants. This camshaft is designed to give your engine a noticeable bump in performance, making it a popular choice for both marine applications and performance-oriented street builds where you want improved throttle response and powerband.

The 212/218 duration at .050 lift is a well-balanced profile for a hydraulic roller setup. It offers a strong torque curve that starts lower in the RPM range and pulls well through the mid-range, without being so aggressive that it makes the engine difficult to drive on the street or requires extensive supporting modifications. The hydraulic roller design itself means less friction and more efficient operation compared to flat tappet cams, contributing to better power and longevity. This camshaft is a solid option if you're looking to get more out of your existing roller-equipped SBC engine.

When installing this camshaft, remember it's designed for engines already equipped with factory roller lifters and rocker arms. Ensure your valve springs are up to the task of handling the increased lift and duration; COMP Cams typically recommends specific spring kits for their camshafts to ensure optimal performance and reliability. This camshaft fits a wide range of vehicles, including models like the Chevrolet Camaro, Corvette, and various C/K series trucks from the late 80s and 90s.
