Hi just wondering on rocker arms on a 2.2 ohv I do beleive the ratio is 1.5 to 1 and was wondering if 1.6 to 1 are available and if anybody has tried them with success thanks Roy
Yeah, MadJack's thread has everything you need to know.
The Comp Cams Magnum aren't worth it, the Crane's are a long-time favorite, the ProForm are decent bang-for-the-buck.

I had the Magnums; they seem to add more noise than power. Because they still have a ball fulcrum, their only gain is in the increased ratio. The Crane/ProForm/Jegs, on the other hand, have a ball-bearing fulcrum and significantly reduce friction.
The 98+ engines already have nice rockers, so any upgrade is really only worth it on 97-.

Good to know. I'm thinking of switching from the magnums to full bearing fulcrum. My valve train is noisy and I think it's those.
