Can anyone tell me the width of the air inlet "snorkel" where it goes into the air cleaner? Looks like 454 and 350 applications are different, but measurements from both might help me. If anyone has a TBI truck with the "K46" option, I'd like to know the same dimension, plus, the dimension of the tube where it connects to the "seperator". K46 is the "pre-cleaner" option, which has 3 "snorkel" pieces, as opposed to one on the non-K46 trucks. Only seen it once but on a carbed vehicle.
