What specific components are included in this COMP Cams K-Kit?

This comprehensive K-Kit includes the camshaft, lifters, valve springs, retainers, valve locks, valve stem seals, and a timing chain set. It also comes with assembly lube and installation instructions to aid in the process.

How can I tell if my Chevrolet Small Block engine has a flat tappet or roller camshaft?

To determine if your engine has a flat tappet or roller camshaft, you will typically need to remove the intake manifold or the timing cover. GM gradually introduced roller camshafts starting in the mid-1980s, so checking these components is the most reliable way to confirm your engine's configuration.

Product Details

COMP Cams is a well-known name in performance engine components, and this Xtreme Energy camshaft kit is built to give your Chevrolet Small Block Gen 1 engine a noticeable boost. Specifically designed for the XE256H-10 profile, this kit focuses on delivering strong torque through the low end and mid-range of your engine's RPM band, while still providing a good, manageable idle. This makes it a solid choice for a wide range of vehicles, including models like the Chevrolet Camaro, Corvette, and various C-series trucks and Suburbans from the 1980s and early 1990s.

This isn't just a camshaft; it's a complete K-Kit designed to ensure you have all the necessary components for a successful installation. Inside, you'll find the camshaft itself, a set of lifters, valve springs, retainers, valve locks, and valve stem seals. To help with the installation process, it also includes a timing chain set and assembly lube, along with decals and instructions. This comprehensive approach means you're getting a well-matched set of parts that work together to achieve the desired performance improvements.

It's important to note that this kit is intended for Chevrolet Gen 1 Small Block engines with flat tappet camshafts. GM began phasing in roller camshafts in the mid-1980s, so it's crucial to verify your engine's configuration before installation. This kit 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; please contact us if your engine falls into this category.
