Quote: I believe you... some have run the stamped rockers at high lifts. I also know quite a few folks have punched holes in them with the pushrod at much lower lifts.
I speared new MP "6-pack" rockers twice on my 440 back in the day running a .509 cam and the recommended springs. You could not get me to run a .500+ cam again with stamped rockers for love or money with a big block.
The new Magnum small blocks seem to have no issues however, I know lots of folks running over 500 lift with them.
funny you mention that because if i DID still run the stamped rockers, my engine wouldnt have eaten a bunch of needle pieces and destroyed itself. They did work fine.
I sure agree with you on the needles. With a stout well oiled shaft MOPAR's don't need them. My favorite types are the ductile iron, Comp Pro Magnum and RAS. All simple, stout and robust plain bearing types when applied correctly. I'm running the Comps.
