<x-charset iso-8859-1>The air around the tranny is dirty and hot. Remember, the tranny generates a good amount of heat! The heat exchanges, if not dumping their heat into the cabin, default to dumping their heat into that 'empty' space. Definitely not a good place to pull air. You don't want to pull air from the ground. The higher the better, period!!! Our cars can't get a ram-air set up because they can't travel fast enough. Even if you had an engine powerful enough to push the car you would have to be traveling over 80mph to even START to begin to feel an inkling of it. Do not -- I repeat -- do not route air from the cooling system to the carbs. It does not push enough air. You will also be stealing the necessary cooling air that the engine uses to keep itself cool. Not a smart idea, especially in warm (not necessarily hot) temperatures. If you want anything close to ram-air then buy a turbo or supercharger. And when you are using positive displacement you MUST encapsulate the carb (areas where the metering jets are) to provide the proper fuel metering to the air being forced down the throat. Shad's set up sounds well thought out but, as can be seen, takes some work. Another option would be to provide a cool air source that bathes the carb air filter with cool air so not all of the air it takes is coming around the engine/tranny areas.
