COMP Cams Camshaft CB XE256H-10

If you're looking to get more out of your Chevrolet Big Block engine, a camshaft upgrade like this Xtreme Energy grind from COMP Cams can make a notable difference. This camshaft is designed to provide increased responsiveness and a broader powerband, giving you more torque and horsepower. It's built to enhance performance without making your vehicle difficult to drive, and it maintains enough vacuum for accessories like power brakes.

The Xtreme Energy profile features quicker valve opening events compared to older camshaft designs, which helps create more area under the lift curve. This translates to better engine breathing and more power, especially when paired with other performance upgrades like headers, a free-flowing exhaust, and an aftermarket intake manifold. While it works well with carbureted setups, you'll see the best results when your engine is breathing freely.

This camshaft is a solid option for a wide range of Chevrolet vehicles originally equipped with flat tappet camshafts, including popular models like the C10 Pickup, Camaro, and Impala from the 1960s and 70s. It's a well-built component designed to give your classic Chevy engine a noticeable performance boost.
