There was a cam comparison in one of the old Direct Connection manuals, for big blocks, I believe, that showed the ET differences with each cam - .484", .509", etc. It was in a 400 and may have been hydraulic cams. But it provided an interesting comparison of each step-up in cams and could offer a clue on what to expect. There may have been one for solids as well.

Anybody know if that is out on the internet somewhere?
