Your cart is empty.These Magnum Roller Rocker Arms for Chevy V8 396-454; Ford Boss 302, 351C-400M; and Ford V8 429-460 applications are the ultimate street rocker. With a 7/16 inch 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 pounds. 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.

Does not fit 1970 Ford 460. Even with pushrod guides and new rocker studs they are the wrong design/shape. Just get 7/16 studs and order some full roller rockers.

I have ran this style lifter on one of my other engines since 1999. Still being used to this day after two rebuilds of the engine. Bought a second pair for another build.The engine does not have crazy high spring pressures and is around 450-500hp

Fast shipping, but a couple of the lock nuts were junk. They backed off within five minutes of adjusting the rockers. This could have destroyed my motor. 24 hours and Comp Cams hasn't responded to my email. Unsat... The rockers themselves seem to be a solid product. They don't fit under M/T valve covers without adjusting a little for clearance. I had to file a little off my drippers in one spot on each. I also picked up some Felpro .313 thick gaskets. My .200 weren't thick enough to clear. Hopefully these will do the trick.
