What the test showed was that the extra airflow from two larger carbs lost power & torque to the smaller carb. The AVS also had annular boosters, which normally increase power.
The engine will only draw the air that it needs; that is what the chart in post #9 is for, to select the correct size carb.
You could put a dominator on a slant six & it will run, but the very low air speed through the large venturiis is going to produce a very poor signal, poor fuel atomisation & poor performance. Atomisation is the key.
