What is the advantage of a roller tip rocker arm?

Roller tip rocker arms reduce friction where the rocker arm contacts the valve stem. This can lead to smoother operation, less wear, and potentially a small increase in effective valve lift compared to standard flat-tip rockers.

What does the 1.52 ratio mean for my engine?

The 1.52 ratio means that for every 1 inch of valve lift at the pushrod, the rocker arm will multiply that to 1.52 inches of lift at the valve. This effectively increases the valve lift, which can improve airflow into and out of the cylinder, potentially boosting performance.

Are these rocker arms self-aligning?

Yes, these COMP Cams Magnum rocker arms are self-aligning, which helps to ensure they stay centered on the valve stem during operation, reducing the risk of them walking off and causing damage.

Product Details

If you're looking to get more out of your Chevrolet Small Block V8 engine, upgrading your rocker arms is a smart move. These Magnum Roller Rocker Arms from COMP Cams are built for street performance applications, helping to ensure you get the most effective valve lift from your camshaft. They're designed to work with 3/8" studs and feature a 1.52 ratio, suitable for a wide range of Chevrolet and Buick vehicles with engines like the 350, 400, or 265 Small Block V8.

Constructed from 8620 chromemoly steel, these rockers are well-built to resist flexing, which is crucial for maintaining consistent valve lift and maximizing the performance gains from your camshaft. The roller tip design helps reduce friction at the valve tip, contributing to smoother operation and potentially longer valve train life. COMP Cams rates these for open spring pressures up to 350 lbs, making them a solid choice for many street performance builds where you're looking for an improvement over stock components.

When installing these, remember they are designed for a 3/8" stud diameter. You'll want to confirm your existing setup matches this before ordering. COMP Cams stamps their logo on the underside of each rocker, so you know you're getting a genuine part.
