1968 340 timing
Looking at the picture of the Ops balancer, I can't believe that those numbers and the mark to the left don't indicate that the dot is 180 degrees out. It's just too perfect to be coincidence! I wish mine were marked like this. It seems to me that the distributor is 180 degrees out and they then moved all the plug wires to make it "right". IMHO I'd pull the distributor, turn the rotor 180 degrees, reinstall it and put the wires where they belong, and then let the timing begin!
