What is the benefit of a roller tip rocker arm?

Roller tip rocker arms significantly reduce friction compared to standard stamped steel rockers. This leads to more efficient operation and helps ensure you achieve the full intended valve lift from your camshaft.

What is the stud diameter for these rocker arms?

These COMP Cams Magnum Roller Rocker Arms use a 7/16" stud diameter, which is common for many Pontiac V8 applications.

What kind of valve springs are recommended for these rockers?

These Magnum Roller Rockers are recommended for applications with less than 350 lbs of open spring pressure. Using springs within this range helps ensure optimal performance and longevity.

Product Details

If you're looking to get the most out of your Pontiac V8 engine, especially for street performance builds, these COMP Cams Magnum Roller Rocker Arms are a solid choice. They're designed to help you achieve more effective valve lift, which translates to better engine breathing and performance. These rockers are built for Pontiac V8s ranging from 265 to 455 cubic inches, fitting a wide array of classic models like the Firebird, GTO, and Grand Prix.

What sets these apart is their construction from 8620 chromemoly steel. This material is known for its strength and resistance to flexing, ensuring that the rocker arm maintains its shape under load and maximizes the lift you get from your camshaft. The roller tip design is key here, as it significantly reduces friction compared to traditional stamped steel rockers. This not only helps with efficiency but also contributes to a more consistent and accurate valve lift, potentially adding 15 to 30 horsepower over stock or lesser quality rockers, especially when paired with valve springs rated under 350 lbs open pressure.

With a 1.65 ratio and a 7/16" stud diameter, these rockers are a direct upgrade for many Pontiac applications. You can spot genuine COMP Cams Magnum Rockers by the logo stamped on the underside, a good indicator that you're getting a well-built part designed for performance.
