COMP Cams Camshaft Kit CS Nx284H-13

If you're building a pro street Chevrolet Small Block Gen 1 engine, especially one intended for multi-stage nitrous kits or a 671 blower, this COMP Cams Camshaft Kit CS Nx284H-13 is designed to give you the performance you're looking for. This kit is built around the Nitrous HP 240/253 hydraulic flat tappet camshaft, which is tuned for applications requiring a 2800+ stall torque converter. It’s a well-built package that aims to provide a noticeable improvement in power for your performance build.

This isn't just a camshaft; it's a comprehensive kit that ensures you have the essential components for a proper installation. Inside, you'll find the camshaft itself, a set of lifters, valve springs, retainers, valve locks, and valve stem seals. It also includes a timing chain set to get your timing dialed in correctly, plus assembly lube to help everything go together smoothly. COMP Cams also includes decals and instructions to guide you through the process. This kit is specifically for Chevrolet Gen 1 Small Blocks, covering a wide range of displacements from 262 to 400 cubic inches, but it's important to verify your block is a flat tappet design and not a factory roller, which became more common in later model years.

This kit is a solid option for those looking to extract more power from their classic Chevrolet V8. It’s important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's instructions for proper installation and compatibility checks, especially regarding specific engine variations like the 1955-1957 Chevrolet 265 engines which may require a groove on the 5th cam journal for oiling.
