Product Details
If you're building a Pro Street machine or a bracket racer looking to squeeze more performance out of your Small Block Chevy, this COMP Cams Xtreme Energy camshaft is a solid choice. It's designed for engines with factory roller camshafts, specifically the Gen 1 Small Blocks found in a wide range of vehicles from the late 80s through the mid-90s, including popular models like the Chevrolet Camaro, Corvette, and various C/K series trucks.
This camshaft features a 248-degree intake and 254-degree exhaust duration at .050 lift, making it well-suited for engines with 10:1 or higher compression ratios and a 3500+ RPM stall speed torque converter. The hydraulic roller design means less friction and more efficient operation compared to flat tappet cams, contributing to its performance potential. It's intended for use with good flowing cylinder heads and headers to help your engine breathe easier and make more power.
When installing this camshaft, ensure you have the necessary supporting components for optimal performance and reliability. This includes a compatible valvetrain and a torque converter that can handle the increased RPM range. Always refer to the manufacturer's installation instructions for specific details regarding setup and break-in procedures.
