from this forum where they are discussing the main body that people get from proform to modify their holleys they are saying the venturi from that main body is 1.39 in primary and secondary and it is the same from 650 to 850.
Proform 67100C 650-800 CFM Holley Carburetor Main Body

My carb is Proform Race Series carb 67199. So based on the part numbers I think mine is the 1.39 venturis

Proform Race Series Carburetors 67199

Proform Main Bodies for Holley Carburetors 67100C

If yours is the 1.39 Venturi and a 1.75 throttle blades that's plenty. If it's the 1.687 throttle blades and you think the carb is acting too small, you can buy a 1.75 base plate, blend the bores to match and run it.
