Re: All is not always as it appears.
Venturi size is not the only thing that determines air flow. Friction with the walls of the carburetor and intake manifold along the whole passage are a very large player in how much air flow can be had. If you put the modified carburetor on a flow stand I would bet money (if I was a betting man) that if flows quite a bit better than a stock 94. In order to use this you would have to have a manifold that also could flow more, or the modification is useless. Also, the center section might be the larger bore Y Block carb.
I also would bet that someone got their inspiration for this from the old Holley 3 barrel carb.
