COMP Cams Magnum Roller Rockers Chevy S

If you're working on a Chevrolet Small Block engine, these COMP Cams Magnum Roller Rocker Arms are a solid option for street performance builds. They're designed to fit a wide range of Chevy V8s from 265 to 400 cubic inches, including popular models like the Camaro, Corvette, and C10 trucks from the mid-50s through the mid-80s. These rocker arms help your engine make more power by ensuring more effective valve lift.

Constructed from 8620 chromemoly steel, these rocker arms are well-built to resist flexing, which is crucial for maintaining accurate valve lift and maximizing the performance gains from your camshaft. The roller tip design significantly reduces friction compared to traditional rocker arms, allowing for smoother operation and potentially longer engine life. They feature a 1.6 ratio and are designed for applications with less than 350 lbs of open spring pressure. Keep in mind that these are non-self-aligning rocker arms, so if your engine originally came with self-aligning rockers, you'll need to use guide plates.

This set includes the rocker arms only. COMP Cams also offers these in kits that bundle them with compatible pushrods, which might be worth considering depending on your engine's specific needs and whether you're rebuilding a flat tappet or roller lifter setup.
