Look on the carb for a small vacuum source above the throttle body. You would want one that has no vacuum at idle.

Where does the vacuum advance on the distributor go does it go to the carb or somewhere else?

It depends on the year of the car.....but if you are running HEI ignition (74 and later) it will run to the carb. It goes to a ported vacuum signal. You will find a ported vacuum on a fitting that is above the carb base plate. It should have no vacuum when the engine is idling but will have vacuum when you rev the engine.

When you get ready to run the vacuum line from the turbo 400 trans modulator to an Edlebrock Performer 800 CFM carb, attach the vacuum line for the transmission vacuum modulator to the bottom constant vacuum source or the plug that is below the throttle plate. After that, install the vacuum advance to the port that is signaled or right above the throttle plate. Once that is completed, install the large vacuum line to the back of the carb for the power brake.

You recently installed a 600cfm edelbrock carb on your 75 Nova you were wondering where do you hookup the distributor to the carb?

There should be two small and one large vacuum connection points on the front of the carb, hook it to one of the small ones, that will be for your vacuum advance. the big one is for crankcase ventilation. one of the smaller ports is manifold vacuum, the other is timed vacuum. they are not the same, but you will use one of these, usually the "timed" port.
