COMP Cams Camshaft CS X4 258HR-11

When you're looking to get more out of your Small Block Chevy engine, especially one that's set up for factory roller lifters, this COMP Cams CS X4 258HR-11 camshaft is a solid choice. It's designed to give you strong torque and maintain good fuel mileage, making it suitable for stock to mildly modified engines. This camshaft is a hydraulic roller type, which means it's built for efficiency and durability in your engine's valvetrain.

This particular camshaft, the Xtreme 4x4 206/210 HR, features a 206-degree intake and 210-degree exhaust duration at .050 inch lift. These specs are tuned to provide a noticeable boost in low-end and mid-range torque, which is exactly what you want for applications like 4x4s or trucks that need to get moving from a stop or tow heavy loads. It's a well-built component that works well with factory roller lifters, simplifying installation in engines originally equipped with them. You'll find it fits a wide range of General Motors vehicles from the late 80s through the mid-90s, including popular models like the Chevrolet C1500, Camaro, and Buick Roadmaster.

For installation, it's important to note that this camshaft is intended for OE roller Small Block Chevy engines from 1987 and newer, specifically excluding LT-1 and LS1 variants. Ensure your engine has the factory roller camshaft provisions before installation. While it offers improved performance and efficiency, it's not CARB approved and cannot be shipped to California.
