Thank you for taking the time to make suggestions I value them.

Well after 5 hours spent trying to verify true TDC marks (see link for sister post below) I think I can tell you what my initial timing is/was.
Finding True Top Dead Center - TDC not so easy?
My initial timing was 19 degrees @ 650 RPM. That was not intentional when I set it, I was trying to get the truck running and move it from one location to my house.
I have since reset it to 12.5 degrees at 850 RPM with a manifold vacuum of 19 Hg. Not sure this is where I will keep it, but I will let the engine cool down then test it again.

There was some anti freeze left over in the motor for sure, so it wasn't 100% water. Also the pressure in the cooling system adds 2 degrees per 1 PSI so at 15 PSI that's 30 additional degrees before we start to make bubbles and steam.

Ha ha, I bet half of them are questions, lol.
