COMP Cams Cam & Lifter Kit CS XR288HR-1

If you're looking to wake up your 1987 and newer Chevrolet Small Block engine with a factory roller camshaft, this COMP Cams Xtreme Energy XR288HR-1 Cam and Lifter Kit is a solid option. This kit is designed for street/strip applications and is a popular choice for builders aiming for a noticeable bump in performance. It’s built to work with engines that have 9:1 or higher compression ratios, and it really shines when paired with intake and header upgrades, and appropriate gearing. You’ll want to make sure your vehicle has a 3000+ RPM stall torque converter to take full advantage of what this cam has to offer.

This kit includes the camshaft itself, a set of hydraulic roller lifters, assembly lube to get everything started right, and decals. The XR288HR-1 camshaft has a 236-degree intake duration and a 242-degree exhaust duration at .050 inch lift, with a .525 inch intake lift and .540 inch exhaust lift. This profile is known for producing a rough idle, which is a characteristic many performance enthusiasts associate with a serious street machine. It’s important to note that this kit is not CARB approved and cannot be shipped to California.

For optimal performance and reliability with this camshaft, COMP Cams recommends ensuring your engine has at least 9:1 compression, and that you have supporting modifications like headers and an improved intake system. A torque converter with a stall speed of 3000 RPM or higher is also recommended to keep the engine in its power band. Always refer to the included instructions for proper installation and break-in procedures.
