COMP Cams Cam & Lifter Kit CS Nx276HR-1

This COMP Cams hydraulic roller camshaft and lifter kit features a 224-degree intake and 236-degree exhaust duration at .050 lift, designed for street machines running a 125+ nitrous system or a small supercharger. It's built for Chevrolet Gen 1 Small Block engines, covering a wide range of displacements from 262 up to 400 cubic inches. This kit is a solid choice for those looking to significantly improve their engine's performance, especially when paired with a 2200+ RPM stall torque converter and lower gear ratios.

The kit includes the camshaft, hydraulic roller lifters, assembly lube, decals, and instructions, providing a comprehensive package for your engine build. It's important to note that this kit is intended for engines with flat tappet camshafts; it does not fit factory roller small blocks from 1985 and newer, nor does it fit any LS-based engines. For 1955-1957 Chevrolet 265 engines, a specific oiling groove on the 5th cam journal is required, so check your specific application.

This camshaft is designed to work well in a variety of Chevrolet applications, including popular models like the Camaro, Corvette, C10, and Caprice. While it's a powerful upgrade for performance builds, it's crucial to verify your engine's original camshaft type (flat tappet or roller) before installation, as GM transitioned to roller cams gradually through the 80s and 90s. For those building a serious street machine, this kit offers a significant performance step up.
