COMP Cams Camshaft CS XR264HR-10

This COMP Cams Xtreme Energy camshaft, part number 12-412-8, is a hydraulic roller grind designed for mild performance upgrades on Chevrolet Gen 1 Small Block engines. You get the camshaft itself, ready to be installed. It's built to offer a noticeable increase in mid-range torque and horsepower compared to stock cams, without making the engine difficult to drive daily. This means you'll feel a stronger pull when accelerating, especially in the RPM range where you do most of your driving, while still maintaining enough vacuum for accessories like power brakes.

The Xtreme Energy profile features a quicker valve opening and more area under the lift curve, which translates to improved engine responsiveness. While it works well with carbureted setups, you'll see the best performance gains when paired with an aftermarket intake manifold, lower gear ratios (like 3.23 to 3.73), headers, and a free-flowing exhaust system. This camshaft is specifically designed for engines that originally used a flat tappet camshaft; it does not fit factory roller small blocks from 1985 and newer, nor does it fit any LS-based engines. It's important to confirm your engine's original setup before installation, as GM transitioned to roller cams gradually.

This camshaft is a solid choice for mild performance builds where you want a noticeable improvement in power and torque without sacrificing the comfortable drivability you expect from your vehicle. It's a popular option for those looking to get more out of their classic Chevrolet V8.
