Ralph, do you recall what the difference was between the 276* and 306* cams (if any)?

I've mostly concluded they were the same grind, just that the "advertised" was measured differently, like 276* at .014" lobe (lash point), or 306* at .005 lobe (more like the way Ford measured their hydraulic cams, and way below lash point for a solid cam).
BUT, this topic goes round-n-round so always looking for more info on that one too.
