It was a vacuum-only for the secondaries.
The butterly openings were 1 11/16" (Primary and Secondary).
Here's the confusion, what was the CFM-rating.
It was 700 CFM.
Holley serial #'s _776 = 600 CFM
_777 = 650 CFM
_778 = 700 CFM (D DART)
_779 = 750 CFM
_780 = 800 CFM
* The D DART carburetor was equipped with a manual choke only.

So what you are saying is the last three numbers in the list number is the CFM rating? Also, I thought the spacer between the carb and the manifold was to allow full openings of the butterflys. If that's true then why did they need to bore out the manifold? I wonder how that motor would of responded to an Edelbrock D4B?
