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.

I don’t it’s only been about 58 years. I do remember that in late 63 after the 427 came out I went to the 27 AA cam which was a SK part number at that time. I got it from Sully(Don Sullivan).

So- my dad who was a div 3 racer and knew bob glidden , said he thinks that cam was for glidden with help from marty barret along with the canadian" heads. Recalls a yelling match between Mr Glidden and a chevy racer at edgewater untill Marty came over and settled the matter by admitting he had got the cam approved. Even though glidden was racing SS at the time but had customers who ran stock.
