Product Details

If you're working on a Chevrolet 396 to 454 Big Block engine, these High Energy aluminum rocker arms from COMP Cams are a solid option. They're designed for street use and moderate racing applications, offering an affordable way to get improved performance. These rockers feature a 1.7 ratio and are built to work with a 7/16" stud diameter.

What sets these apart is their die-cast aluminum construction, which is lighter than stock but still strong enough to handle the demands of a performance engine. The real benefit comes from the needle bearing fulcrum and roller tip. This setup creates significantly less friction compared to standard sliding rocker arms. Less friction means lower oil temperatures, which can lead to a more responsive engine and a slight increase in horsepower. They're built to withstand up to 550 lbs of open spring pressure, giving you more flexibility with your valve lift.

These rocker arms are a cost-effective upgrade for your Big Block Chevy. They use snap rings to keep the trunnion and bearings securely in place, ensuring durability. If you're looking to get a bit more out of your engine without breaking the bank, these are definitely worth considering.
