Comp Cams1411-16 Magnum Roller 1.72 Ratio Rocker Arm Set BBC, Ford 429-460, 351C/M w/ 7/16" Stud

great product but didn't work for my application.

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.

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

Slow shipping but rocks are very good

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.

GOOD

Boughts these back in sept and absolutely love them they dont flext or backout at high roms and i would definately recommend to use on any street or strip application for the price cant beat their chromoly

described made of crystal and is plastic.

Very noisy
