RB Engine in A bodies - Air Cleaner Clearance Issues
440 in my Demon. Performer RPM intake. I don’t have a picture but I did recently install the K&N Extreme top. 14”X 3” element with 1 3/4” all star drop base on the air cleaner. The retaining nut for the air cleaner hits the insulation. Keep in mind from what I can tell with your setup you may have to rework the lines and things connected to your carburetor with a drop base. I am running a Mopar DC k frame also. There may be some variances from each individual set up depending on how the engine is adapted to fit the K frame and other variances.
