I agree if I could raise it up and make a smoother entry into the carbs it would only help. Just no room. I have an air filter that fits. Just need to make sure it will flow enough. That would break up the turbulence and smooth the air out. Or leave the lid off and seal it to the hood so it takes air from the ducts and scoop. Another option is put a divider in so one inlet feeds one carb. Likely try all 3 in a couple weeks.
