COMP Cams Camshaft Kit CS XR276HR-10

When you're building a high-performance street machine and want that unmistakable choppy idle, this COMP Cams Xtreme Energy K-Kit is a solid choice. This kit is designed for Small Block Chevrolet engines from 1987 and newer that came with factory roller camshafts, like those found in many Chevrolet Camaros, Corvettes, and pickup trucks. It's intended for use with a 2000+ stall torque converter and appropriate gearing to really let this camshaft shine.

What you get in this kit is everything you need to swap out your old camshaft and get a significant performance upgrade. It includes the XR276HR camshaft itself, a full set of hydraulic roller lifters, valve springs, retainers, valve locks, and valve stem seals. To make sure the installation goes smoothly, it also comes with a timing chain set and assembly lube. COMP Cams even includes decals and instructions to guide you through the process.

This camshaft kit is built for performance, featuring a 224-degree intake duration and 230-degree exhaust duration at .050 inch lift. The .574-inch intake lift and .578-inch exhaust lift, combined with a 110-degree lobe separation angle, contribute to its aggressive idle and strong performance in the mid-range and upper RPMs. It's a comprehensive package designed to change the character of your engine for a more spirited driving experience.
