This Magnum Roller Rocker Arm is tailored for AMC V8 290-401; Ford V8 289-351W (Non Rail) 1961-67; and Oldsmobile V8 260-455 applications, delivering ultimate street performance. Featuring a 3/8" stud diameter and 1.6 ratio, it's designed for dedicated performance enthusiasts. Constructed from 8620 chromemoly steel, a superior material offering maximum lift without flex, these rocker arms boast a roller tip to reduce friction. With a stiff design and superior ratio accuracy, they ensure more effective valve lift, translating to a 15 to 30 horsepower increase over alternative rocker arms. Perfect for performance applications with less than 350 lbs. open spring pressure, insist on the COMP Cams® logo stamped into the underside of every Magnum Rocker to avoid inferior products or cheap knock-offs.
