1960 rough engine Timing question

[David Greenburg]

On these older cars, I like to time them using a vacuum guage.  Old school mechanic taught me this many years ago when I was traveling between the Rockies and the east coast with some regularity. Turn the distributor until you get max vacuum, and the back it off 3/4"-1" (depending on how good your gas is. This adjusts for altitude, engine wear etc. and may also help to confirm/deny a vacuum leak.

Our 55 has vac advance for the booster, distributor advance, and the wipers/antenna.
I know yours is different, but I would unhook all vac accessories and cap them. If not,you will be chasing your tail if you have a leaking booster for example.

Can anyone confirm he has the correct layout and firing order and rotation?  Not just google, when I google it I do get some that match what he drew but I also get several that I know are not correct.  We need to know for sure is is working with the correct layout before continuing.
