Product Details

This COMP Cams camshaft kit is built around the XS274S-10 solid flat tappet camshaft, featuring a 236/242 degree intake/exhaust duration. This specific grind is known for creating strong mid-range torque and improved throttle response, making it a popular choice for performance builds where that powerband is crucial. It's designed to work well with a 2200+ stall speed torque converter, which helps keep the engine in its powerband during acceleration.

The kit includes everything you need to get the camshaft installed: the camshaft itself, a set of lifters, a timing chain set for proper valve timing, assembly lube to protect the new components during initial startup, and decals. This is a solid option for Chevrolet Gen 1 Small Block engines, covering a wide range of displacements from 262ci up to 400ci. It's important to verify your engine uses a flat tappet camshaft, as many later model Small Blocks (especially from 1985 and newer) transitioned to factory roller camshafts, which are not compatible with this kit.

When installing this kit, remember to check your specific engine's requirements. For instance, 1955-1957 Chevrolet 265 engines need a groove on the fifth cam journal for proper oiling. Always refer to the included instructions for the most accurate installation details and to ensure you get the best performance from your new camshaft.
