COMP Cams Camshaft CS XR252HR-10

This COMP Cams Xtreme Energy camshaft features a 200/206 degree intake/exhaust duration split, a common choice for Small Block Chevy engines looking for improved performance without sacrificing drivability. It's designed to work with factory roller camshaft setups on 1987 and newer GEN 1 Chevrolet 305-350 small blocks, excluding LT-1 and LS1 variants. This camshaft is a solid option if you're aiming for better towing capability and improved fuel mileage, all while maintaining a smooth idle. It's also engineered to work with stock torque converters and rear gear ratios, simplifying installation.

The hydraulic roller design means less friction and more efficient operation compared to flat tappet cams. This particular grind, the XR252HR-10, is known for its ability to provide a noticeable bump in power and torque across the RPM range, making it suitable for a variety of applications from daily drivers to work trucks. You can expect a noticeable difference in how your engine pulls, especially when under load, and it's designed to be compatible with stock engine components, making it a straightforward upgrade for many vehicles.

This camshaft fits a wide range of classic Chevrolet and Buick vehicles from the late 80s through the mid-90s, including models like the Chevrolet Camaro, Corvette, C/K trucks, and Buick Roadmaster. It's a well-built component that offers a good balance of performance and everyday usability for your Small Block Chevy.
