COMP Cams High Energy Alum Rocker SBC 1.

If you're looking to get a little more out of your Small Block Chevy engine, especially for street use or moderate racing, these High Energy aluminum rocker arms from COMP Cams are a solid option. They're designed to replace your stock rocker arms and offer an improved valve lift thanks to their 1.6 ratio. This means you can potentially see better throttle response and a slight bump in horsepower.

What sets these apart is the combination of a die-cast aluminum body and a roller tip with a needle bearing fulcrum. This setup significantly cuts down on friction compared to the sliding contact of factory rockers. Less friction means less heat buildup, which can help lower oil temperatures and contribute to improved engine performance. The aluminum construction also keeps the overall weight down while still being strong enough to handle up to 550 lbs of open spring pressure, making them a durable choice for performance applications.

These rocker arms are built to fit a wide range of Chevrolet V8 engines from 265 to 400 cubic inches that use a 3/8" stud. You'll find them commonly installed in vehicles like the Chevrolet Camaro, Corvette, and Caprice, among many others from the 1980s and early 90s. They are a cost-effective way to upgrade your valvetrain.
