It's a 340 and I have an rpm air gap with a 1inch spacer on it, I took the spacer out due to clearance but then my butterfly's on the carb hit the intake. So I bought a drop base air cleaner hoping that'll fit. But still won't happen. I haven't measured exactly yet, but from eye balling across my fender, it looks like the top of the air cleaner is 1 inch or maybe a bit more above the fender.
