Every vintage civilian car I've ever worked on has it mounted directly over the carb, so go figure. And, of course, the Model T had absolutely nothing to filter air unless it was after market.

Engine ventilation is not the same as air filtration for the carburetor.
I sorta glossed over this at first, but after reading the last couple of posts, I took a closer look. From what I can see (it's not exactly clear from the pictures), it appears the O/P has reversed the flow of air through the engine so it functions like the earlier engines rather than the improved 8BA method. If this is the case, I am surprised it works as well as he says. It is contrary to the basic design of the 8BA engine. I sure wouldn't recommend it over a properly installed PCV system (or the original system, for that matter).
