COMP Cams Camshaft Kit CS XR274R-10

If you're looking to significantly boost the performance of your Chevrolet Small Block Gen 1 engine, this Xtreme Energy solid roller camshaft kit from COMP Cams is a serious upgrade. This kit is designed for enthusiasts who want to unlock more power and torque, especially in applications where aggressive engine builds are common. It replaces your stock flat tappet camshaft and lifters with a high-performance solid roller setup, which is known for its ability to handle higher RPMs and more aggressive valve events.

This SK-Kit, part number SK12-770-8, comes with everything you need to get started: the XR274R-10 camshaft itself, a set of solid roller lifters, a new timing chain set to ensure precise valve timing, assembly lube to protect components during initial startup, and decals. The camshaft features a 236-degree intake and 242-degree exhaust duration at .050 inch lift, with a .571 inch intake and .590 inch exhaust lift, making it a potent choice for street/strip applications. Remember, this kit is intended for engines that originally came with a flat tappet camshaft; if your engine was built from 1985 onward and may have a factory roller setup, it's crucial to verify by removing the intake or timing cover before ordering.

This kit fits a wide range of Chevrolet Small Block Gen 1 engines, including popular displacements like the 262, 283, 305, 327, 350, and 400. It's a popular choice for vehicles like the Chevrolet Camaro, Corvette, Caprice, and C10 trucks from earlier eras. Please note that this kit is not CARB approved and cannot be shipped to California. For 1955-1957 Chevrolet 265 engines, ensure there is a groove on the 5th cam journal for proper oiling; contact COMP Cams for specific details if needed.
