What is the main benefit of using a roller rocker arm?

Roller rocker arms, like these Magnum models, feature a roller tip that significantly reduces friction compared to standard flat-tip rockers. This lower friction allows for more efficient valve lift and can contribute to a small horsepower increase.

What does the 1.7 ratio mean for my engine?

The 1.7 ratio means that for every 1 inch of valve lift at the cam lobe, the valve will open 1.7 inches. This effectively multiplies your camshaft's lift, allowing for more air and fuel into the cylinder.

Does this rocker arm come with all the necessary hardware for installation?

This product includes the Magnum Roller Rocker Arm itself. It is designed to work with your existing 3/8" studs and rail-type setup. Always refer to the manufacturer's installation instructions for any additional hardware or specific procedures.

Product Details

COMP Cams is well-known for making performance engine parts, and their Magnum Roller Rocker Arms are a popular choice for street performance builds. This particular rocker arm is designed for Ford small block V8 engines like the 289 and 351 Windsor, specifically those with a 3/8" stud and rail-type setup from 1968 to 1989. It's built to give you more effective valve lift compared to stock rockers.

Constructed from 8620 chromemoly steel, these rockers are built strong and won't flex, which helps ensure you get the maximum lift from your camshaft. The roller tip on this arm is key because it reduces friction as it rolls against the valve stem or valve seal, leading to a smoother operation and potentially a small horsepower increase over standard rocker arms. They are rated to handle up to 350 lbs of open spring pressure, making them a solid option for many street performance applications.

This part fits a wide range of Ford vehicles, including models like the Ford Bronco, F-150, and Gran Torino from the late 60s through the 90s. Make sure your engine uses the 3/8" stud size and the rail-type configuration to ensure proper fitment.
