COMP Cams Camshaft CS XR268 R-10

COMP Cams has built a reputation for making serious performance engine parts, and their Xtreme Energy camshafts are a popular choice for anyone looking to get more out of their engine. This particular camshaft, the XR268 R-10, is designed for Chevrolet Small Block Gen 1 engines and aims to give you a noticeable bump in power without making the car undrivable. It works by opening the valves quicker and keeping them open longer, which means more air and fuel can get into the cylinders and more exhaust can get out. This translates directly to increased torque and horsepower, especially when paired with other performance upgrades like headers and a free-flowing exhaust.

What's great about the Xtreme Energy line is that COMP Cams engineers them to increase performance while still maintaining adequate vacuum for essential accessories like power brakes. This means you can get that improved throttle response and power gain without sacrificing everyday creature comforts. This camshaft is a solid option for a weekend cruiser with a compression ratio of 9:1 or higher, a torque converter with a 2000+ RPM stall speed, and lower rear-end gears. You can expect a noticeable idle with this cam, which is a good indicator of the increased performance it brings.

This camshaft is designed for a wide range of Chevrolet Small Block Gen 1 engines, including popular displacements like the 262, 283, 305, 327, and 350. It's important to note that this camshaft is a flat tappet design and will not fit factory roller camshaft blocks, which were gradually introduced in 305s and 350s from the mid-80s onward. Vehicles like Camaros, Firebirds, and Corvettes received roller cams earlier, while trucks and SUVs sometimes retained flat tappet cams into the mid-90s. Always confirm your block type by removing the intake or timing cover before installation. This camshaft is not CARB approved and cannot be shipped to California.
