What is the main benefit of using roller rocker arms over stock ones?

Roller rocker arms, like these from COMP Cams, feature a roller tip and needle bearing fulcrum. This design significantly reduces friction compared to the sliding action of stock stamped steel rockers, which can lead to lower oil temperatures and improved engine response.

What size studs do these rocker arms require?

These COMP Cams High Energy rocker arms are designed for engines using a 7/16-inch stud diameter. It's important to confirm your cylinder heads are equipped with the correct size studs before installation.

Can these rocker arms be used with high-lift camshafts?

Yes, these rocker arms are designed to be stiffer than stock and can withstand up to 550 lbs of open spring pressure, allowing for increased valve lift and supporting moderate performance camshafts.

Product Details

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 the stock stamped steel rockers on a wide range of Chevy V8s, from 265 cubic inches all the way up to 400 cubic inches, including popular models like the Camaro, Chevelle, and C10 trucks.

What sets these apart is the aluminum construction and the roller tip with a needle bearing fulcrum. This setup significantly cuts down on friction compared to the old sliding factory rockers. Less friction means lower oil temperatures, which can lead to improved engine response and a small bump in horsepower. The aluminum body itself is well-built, offering a good strength-to-weight ratio, and they're designed to be stiffer than stock, allowing for a bit more valve lift while handling up to 550 lbs of open spring pressure. They use snap rings to keep the trunnion and bearings securely in place.

These rocker arms are a cost-effective way to upgrade your engine's valvetrain. Just make sure you're using a 7/16-inch stud diameter on your heads, as that's what these are built for.
