Product Details

COMP Cams is well-known for making performance parts that help engines breathe better and make more power. This Xtreme Energy camshaft, the CS XR269HR-12, is built for Chevrolet 305 and 350 small-block engines that came with factory roller camshafts, like those found in many 1987 and newer trucks and cars. It's designed to give you a noticeable bump in performance, especially in torque and horsepower, without making your daily driver uncomfortable or killing your gas mileage.

What makes this camshaft stand out is its quicker valve opening profile, which means more air and fuel get into the cylinders faster. This translates to better responsiveness and a broader powerband, giving you more grunt when you need it. While it works with carbureted setups, you'll see the best results when paired with an aftermarket intake manifold, better exhaust, and lower gear ratios. Because it's computer-controlled, it requires custom tuning to get the most out of it and ensure everything runs smoothly. This camshaft is a solid choice for anyone looking to improve their engine's performance on a range of vehicles, including models like the Chevrolet Camaro, Corvette, and C1500 Suburban.

This camshaft is designed for OE roller SBC engines and requires custom tuning for optimal performance. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and any additional components you might need.
