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.
