It was the wrong harmonic balancer. Got the new one installed buttoned everything up.
Still couldn't get it to run till I set my timing around 60deg.... than my buddy 800 miles away suggested when I rewired the truck I must have swapped the wires on the distributer.
Swapped two wires, and got it running with 10deg btdc. Mechanically it advances to 30deg.
With vacuum it only gets up to 32deg.
It idles great, but when starting it sometimes gets stuck at 300rpm, until I hit the throttle. It runs fine until I hammer down from cruise to wide open. I can idle and cruise all day, I can even ease into WOT but I can't slam it.
