Comp Cams Magnum Roller Rocker Rocker Arm; Includes 7/16"
This Magnum Roller Rocker Arm for Pontiac V8 265-455 applications is the ultimate street rocker. With a 7/16" stud diameter and 1.65 ratio, it is designed for serious performance enthusiasts. All Magnum Roller Rocker Arms are constructed from 8620 chromemoly steel, which is a superior material that will not flex and assures maximum lift. Their roller tip reduces friction, while stiff design and superior ratio accuracy yield more effective valve lift. With a 15 to 30 horsepower increase over other rocker arms, Magnum Roller Rockers are perfect for performance applications with less than 350 lbs. open spring pressure. Don't accept inferior products or cheap knock-offs, look for the COMP Cams® logo stamped into the underside of every Magnum Rocker
