On my 76, there is a nipple that comes up out of the manifold directly in front of the distributor. There are two outlets on this nipple - 1 for the transmission vacuum and another for the headlights. I usuallly pull the plug for the headlights and check for manifold vacuum there. This is a Edelbrock manifold but the factory manifold was the same.

yes it's for Vacuum advance. the mechanic that originaly set up my rebuilt engine did not hook up the vacuum advance and i did not know enough about it at the time to question him why. down loaded Lars paper on timing and am going to give it a try. sorry, no power brakes. big port in the back center of carb feeds my head lights.
thanks.....
