It works great, but one thing that I've noticed is that is has no connection for ported vacuum. The typical location to the right of the fuel inlet is blank. I believe that the factory setup uses the TVS switch on the intake and the hoses routed to manifold vacuum, ported vacuum, and another hose to the distributor. in any event, it has a hose that's supposed to go to a ported connection. So the question is, if there is no connection to a ported outlet to the right of the fuel inlet, and none on the side either, where does a '70 GTO get the ported vacuum source? I was thinking of just getting an earlier carb with the ported connection to the right of the fuel inlet, but I wanted to check first. Thx.

You can add a ported vacuum advance port if you want one.
