COMP Cams Camshaft Kit CS XR288HR-10

If you're looking to wake up a classic Chevrolet Small Block engine for street and strip use, this COMP Cams Xtreme Energy Camshaft Kit is a solid choice. This kit is designed for engines with around 9:1 compression and is intended to be paired with headers, a higher stall torque converter (2800+ RPM), and appropriate gearing to make the most of its performance potential. The XR288HR-10 camshaft itself features a 236-degree intake duration and 242-degree exhaust duration at .050 lift, with a .552-inch intake lift and .552-inch exhaust lift, giving it a noticeable, rough idle that signals serious intent.

This kit includes everything you need to get the camshaft installed and running: the camshaft itself, a set of hydraulic roller lifters, a complete timing chain set, assembly lube to ensure proper break-in, and decals for that authentic look. It's built for Chevrolet Gen 1 Small Blocks, covering a wide range of displacements from 262ci up to 400ci. It's important to verify your engine is a flat tappet block, as this kit is not compatible with factory roller blocks from 1985 and newer, nor is it for the modern LS-based engines.

For optimal performance, this camshaft kit is recommended for applications using headers and a torque converter with a stall speed of 2800 RPM or higher. It's also best suited for vehicles that will be running deeper gear ratios. While it provides a rough idle, it's still manageable for street use when properly set up with the right supporting components. This kit is a comprehensive package for those serious about extracting more power from their classic Chevy V8.
