You need to place the vac***** port at the point of maximum vacuum. This would probably be point of greatest restriction, between the carbs and the engine.



www.rx7club.com is a good resource for these questions.

Below the venturi and above the throttle blade, or at least the position where the throttle blade closes at idle.



In a pinch, it is possible to run the distributor off manifold vacuum. Not optimal, but it'll work.



Or you could just leave off the vacuum advance altogheter, particularly if this is a race motor.
