I think the intent is a stud mount must still be a stud mount, a shaft must remain a stock shaft location. Some people will be affected in that the specs might call for a 1.5, and of course there are usually no numbers on the stamped steel or ductile iron(Mopar), and almost all of the aftermarket has the ratio on them. Might affect camshaft etc, and is very easy to look at by Tech Inspectors. That is what got me pitched earlier. Cam checked, but the specs say 1.6 and I had 1.65 and I went home. That's my story and I'm sticking to it.

I spoke with Mr. Gracia at PRI and what Jeff posted is pretty much it. He told me he had looked at the Harland Sharp rockers and approved them. Yellow Terra Rockers submitted a set while at the show. Apparently almost any rocker, aluminum, steel, needle bearing, sleeved or whatever kind of roller tip is ok as long as it will directly replace the stock rocker with no machining and check at stock ratio spec. MoPars must use and fit stock shafts for example. Jim
