COMP Cams Cam & Lifter Kit CS XR288HR-1

This COMP Cams Cam & Lifter Kit CS XR288HR-1 gives you everything you need to get a significant upgrade for your Chevrolet Small Block engine. Inside this box, you'll find the XR288HR-1 camshaft itself, a set of hydraulic roller lifters designed to work with it, assembly lube to get everything started right, and some decals to show off your new performance parts. This kit is built for street/strip applications and is designed to work with engines running around 9:1 compression, requiring headers, and a stall converter of 2800 RPM or higher, along with appropriate gearing.

The XR288HR-1 camshaft features a 236-degree intake duration and 242-degree exhaust duration at .050 lift, with a .520-inch intake lift and .540-inch exhaust lift. This profile is known for creating a rough idle, which is a characteristic often desired in performance builds. It's important to note that this kit is intended for Chevrolet Gen 1 Small Blocks and does not fit factory roller small blocks from 1985 and newer, nor does it fit any LS-based engines. Always confirm your engine's configuration before installation, as GM transitioned to roller cams gradually.

This kit is a solid choice for those looking to build a street-friendly performance engine that can also handle track duty. While it's designed for a rough idle, it offers improved performance over stock cams when paired with the right supporting modifications like headers and a higher stall torque converter. Remember to check the specific fitment for your vehicle, as this kit covers a wide range of Chevrolet Small Block applications from 1980 through 1996, but requires careful verification for factory roller setups.
