Choke Tower Carb without Air Cleaner Myth
I don't know about all that. What I do know is that GM did huge research and development on air cleaners and their effects on air flow. Moroso even picked up on it and ran further with their line of air cleaners. If you notice how they are made. The "dome" on the top cover acts like an airplane wing and makes the air on the long side (the top) move faster than the bottom so it all gets to the carb at the same time. It also is supposed to result in less turbulance. As for the chock or no choke tower, I don't necessarily think that holds water. I believe the air will flow just as good one way or the other.
