COMP Cams Camshaft CS 290H-R12

This is the COMP Cams CS 290H-R12 hydraulic roller camshaft, designed for street and strip applications on 1987 and newer Chevrolet Small Block engines equipped with factory roller camshafts. It's a popular choice for those looking to significantly improve their engine's performance beyond stock, especially when paired with other modifications.

The CS 290H-R12 features a 230-degree intake and 244-degree exhaust duration at .050 lift, making it a potent camshaft for performance builds. To get the most out of this camshaft, it requires a torque converter with at least a 2500 RPM stall speed, lower rear-end gears to keep the engine in its power band, and custom engine tuning to optimize fuel and spark delivery. This setup is well-suited for vehicles like the Chevrolet Camaro, Corvette, or C1500 pickup trucks from the late 80s and early 90s, offering a noticeable increase in power and responsiveness.

When installing this camshaft, remember that it's intended for performance use and requires supporting modifications to function correctly. Ensure your engine's valvetrain is in good condition, and consider consulting with a professional tuner to dial in the custom tune for your specific setup.
