Product Details
This COMP Cams Xtreme Energy camshaft kit is built around a hydraulic roller camshaft with a 224-degree intake and 230-degree exhaust duration at .050 inch lift. This specific grind is designed for high-performance street machines that are looking for a noticeable chop at idle, and it pairs well with a torque converter in the 2000+ RPM range and a gear ratio that complements the camshaft's powerband. It's intended for use in Chevrolet small block engines from 1987 and newer that came factory-equipped with a roller camshaft, such as those found in many Chevrolet and GMC trucks, as well as performance cars like the Camaro and Corvette.
The SK-Kit, or Small Kit, is a well-thought-out package that includes everything you need to get the camshaft installed correctly. You'll find the camshaft itself, a set of hydraulic roller lifters designed to work with the cam lobes, a new timing chain set to ensure precise valve timing, and assembly lube to protect the components during initial startup. COMP Cams also includes decals and instructions to guide you through the process. This kit is a solid option for someone rebuilding the top end of their engine and wanting a significant performance upgrade over stock.
This kit is designed to fit a wide range of vehicles, including models like the Chevrolet Camaro, Chevrolet Corvette, and Buick Roadmaster from the late 80s and 90s, as well as numerous Chevrolet and GMC C/K series trucks and vans. It's important to note that this camshaft is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for specific details regarding setup and break-in procedures.
