Any body know where the smaller vac port on the vac block thats sits behind the carb goes? I looked in a diagram and it only shows where the big port goes. Dunno where the liitle one goes to.
If you've got an automatic trans, the little one would run to the vac. modulator valve on the trans. The large one was for power brakes. Any others would have been supply for any vacuum operated accessories in the car.
