What is the main benefit of using roller rocker arms?

Roller rocker arms, like these COMP Cams Magnum models, reduce friction at the valve tip due to the roller design. This allows for more of the camshaft's lift to be transferred to the valve, potentially leading to improved engine performance.

What type of engine builds are these rocker arms best suited for?

These Magnum Roller Rockers are ideal for street performance applications. They are recommended for engines with less than 350 lbs of open spring pressure, making them a good fit for many modified Pontiac V8s that see regular driving.

Do these rocker arms come with the necessary hardware for installation?

This set includes the rocker arms themselves. You will need to ensure your Pontiac V8 has the correct 7/16" studs and compatible valve springs for proper installation. Refer to the manufacturer's instructions for full details.

Product Details

Starting with 8620 chromemoly steel, these COMP Cams Magnum Roller Rocker Arms are built for serious street performance. This strong material won't flex, ensuring you get the most effective valve lift from your engine. They fit a wide range of Pontiac V8 engines, from 265 to 455 cubic inches, and use a 7/16" stud diameter.

The roller tip design on these rockers significantly reduces friction compared to stock components. Combined with a 1.52 ratio, this means more of your camshaft's lift translates to actual valve opening, potentially increasing horsepower over standard rocker arms. They are well-suited for performance builds with less than 350 lbs of open spring pressure, making them a solid choice for many street-driven Pontiacs like the Firebird, GTO, or Grand Prix.

When you're looking for improved valve lift and reduced friction, these Magnum Roller Rockers are a popular option. Make sure to look for the COMP Cams logo stamped on the underside to confirm you have the genuine article.
