I searched & replies were all over the place.

Please confirm that w/the #1 piston @ TDC on the COMPRESSION stroke, both the CAM DOT & the CRANK DOT are in the 12 O'clock postion. This is the correct orientation, cam to crank.

DOT to DOT ocurrs @ the bottom of the #1 piston stroke.

NO!!!

Cam gear dot in the 6 O'Clock position and crank gear dot in the 12 O'Clock position is dot-to-dot.
As in the dots are as close to each other as possible.

So, w/ #1 piston @ "TDC," Cam dot is 6 O'clock & crank gear @ 12 O'clock. OK, got it, thanks for the reply. I appreciate the help.

Yes. You were at TDC on the exhaust stroke. Its 6 o clock cam and 12 o clock crank just like stated for TDC on compression stroke.

jeez if you had left it like that and fired it up it would have made some very interesting noises. None to your liking im sure.

With both the crank gear and cam gear dots at 12 o clock, the engine will start and run just fine.

Well, without incodent anyway; like 4 cylinders on & 4 off & a bit out of balance. No interference though, as you have noted.

Thats exactly correct. The cam spins once for every 2 rotations of the crank, hence the reason why the cam gear is exactly twice as big. Every other rotation of the crank (when its on 12 o clock) the cam is at 12 o clock, and then the following rotation the cam comes back to 6 o clock as the crank comes back to 12 o clock.
