If you were using a dietributor you would use vacuum from both sides, 1 and 4, T it and run it to the distributor.

Bruce,
I forgot to mention that the stock SC distributor for the ignition is omitted (deleted). The vacuum is needed for determining MAP (manifold absolute pressure) during tune-up (mapping). I'm computer challenge so don't ask me anything about 'mapping'.
I've done a few SC engines and this is the first time I got involve in a radical engine. I am doing all the mechanical assembly and adjustment during the rebuild as per spec or request by the engine owner who is a friend actually like a son to me. The ECU by Tec-3R technology would be the control and brain for the ignition with relation to the intake manifold pressure. This is my layman's understanding of the system for this particular project. Maybe someone knowledgeable would chime in and educate us.
One more question: What spark plugs (12) would be good for this engine? I have no idea at this point.
