COMP Cams Camshaft CS 260H-R10

If you're looking to get more out of your classic Chevrolet small block engine, especially in a truck, van, or a vehicle used for towing, this COMP Cams Magnum 206/206 Hydraulic Roller Camshaft is a solid option. It's designed to provide a smooth idle and good mileage, making it a practical choice for daily drivers or work vehicles that still want a bit more performance than stock. This camshaft is intended for use with stock rear gear ratios and a stock torque converter, simplifying installation and compatibility with your existing drivetrain.

This camshaft is a hydraulic roller type, which generally offers better performance and durability compared to flat tappet designs. It features a 206-degree intake and 206-degree exhaust duration at .050 lift, a common specification for a mild performance upgrade that won't sacrifice drivability. The Magnum series from COMP Cams is known for its well-built components, and this camshaft is no exception. It's engineered to work with a wide range of Chevrolet Gen 1 Small Block engines, including popular displacements like the 350, 305, and 400 cubic inch V8s.

It's important to verify your specific engine block's configuration before installation. This camshaft is designed for blocks that use a flat tappet camshaft or have provisions for a factory roller camshaft. It does not fit LT1/LT4 engines or later model factory roller small blocks (typically 1985 and newer, though this varied by vehicle and application). Removing the intake manifold or timing cover is the best way to confirm if your block is a factory roller or flat tappet. For 1955-1957 Chevrolet 265 engines, a specific oiling groove on the fifth cam journal is required; please contact us for details if this applies to your build.
