Product Details
This is the COMP Cams CS 240AH-8 Hydraulic Flat Tappet Camshaft, designed as a 50-state legal performance upgrade for many 1958-1998 Small Block Chevrolet engines, specifically for carbureted V8s built before 1987. It's a well-built component that aims to improve your engine's torque and fuel efficiency, especially in 262-305 cubic inch applications paired with higher axle ratios, all while maintaining a smooth idle.
This camshaft is a popular choice for builders looking for a noticeable improvement without sacrificing drivability. It's engineered to work with flat tappet valvetrains, and while many later model engines switched to roller cams, it's important to confirm your specific block's configuration. The design focuses on delivering strong low-end torque, which is great for getting your vehicle moving from a stop, and it's CARB EO approved, meaning it meets strict emissions standards in California and other states that adopt those regulations.
When installing this camshaft, remember that some 1955-1957 Chevrolet 265 engines require a specific oiling groove on the fifth cam journal. Always refer to the manufacturer's installation instructions for proper setup and to ensure compatibility with your engine's specific build.
