COMP Cams Magnum Roller Rocker Pontiac

Starting with 8620 chromemoly steel, these COMP Cams Magnum Roller Rocker Arms are built to handle the demands of street performance builds. This material is chosen because it's strong and won't flex, which helps ensure you get the maximum possible valve lift from your camshaft. The roller tip design is a key feature here, as it significantly reduces friction compared to traditional stamped steel rockers. This means more of your engine's energy goes into opening the valve, leading to more effective lift and better performance.

With a 1.52 ratio and a 7/16" stud diameter, these rockers are specifically designed for Pontiac V8 engines ranging from 265 to 455 cubic inches. They are well-suited for applications with less than 350 lbs of open spring pressure, making them a popular choice for many street-driven performance cars. You'll find these fit a wide range of vehicles, including many Pontiac Bonneville, Catalina, and Firebird models from the 1950s through the early 1980s.
