    COMP Cams Magnum Roller Rocker Arms, 1.72 ratio, 7/16" Stud Diameter for Big Block Chevy, Set of 8.

    These Magnum Roller Rocker Arms for Big Block Chevy 396-454 applications are the ultimate street rocker. With a 7/16" stud diameter and 1.72 ratio, they are 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.
