The one I use is a Moroso, I think, that has the proper block off for the internals, not just a straight shaft.
My wheat/chaff comment was not directed at you. We seem to agree.
It was a general comment for people to have some idea of the source's validity before they take what is posted as gospel.

With all due respect to Stingr69, #1 and #6 cannot both be at TDC at the same time. If #1 is TDC, then #6 is BDC (BOTTOM dead center) and as far away from firing as possible. Looking at illustrations of cam install instructions, it seems that both scenerios actually achieve the same thing....proper phasing if the cam with the crank. The "dots" are for reference only, not for order. 1-8-4-3-6-5-7-2 equals 6-5-7-2-1-8-4-3....the rotation remains the same and is followed whether you begin with #6 or #1. So, crank 12 & cam 6 position is correct when #1 piston is up (firing position) if you drop in the dist. pointing at #1,.......and both dots at 12 would bring #6 up if you rotated, and you would install the dist. to #6 for correct timing..........BUT, you could also have #6 at TDC (firing) and have the dots line up at 6 and 12, and achieve the same thing- remember, the cam turns at half crank speed, so a 180 deg. turn WITHOUT TURNING THE CRANK when installing your cam would do this and the cam would still be in phase........remember 6-5-7-2-1-8-4-3 equals 1-8-4-3-6-5-7-2...............clear as mud, right?......

Question is...Does the original poster, vettepilot68, now have a "clear" understanding?
