Quadrajet question
Have a quadrajet on a 72. The front vacuum port is plugged which I understand to be normal. It has one on the passenger side near the choke setup that is open and not capped. What is this supposed to go to or should it be capped? Here’s a pic.

Re: Quadrajet question
It's called a diverter port. I have no idea what it would be used for, but I think it has vacuum at idle. Mine is capped.

Re: Quadrajet question
The one on the side of the carb is a manifold vacuum source for the air cleaner Thermac snorkel valve.
If you are looking for the utmost correct look, the TCS emission control system is missing, and it appears the lines to the charcoal canister are gone.
