run some Ford Holley 1 bbl carbs from a 50's inline Ford, and you would reduce the overall height by a couple inches with would allow you to run most air cleaners.
These carbs have a beveled rim, so you would either need to adapt the base of the Ford air cleaner to whatever it is you want to use, or mill/grind off the bevel so you can use a conventional filter base. An adapter ring may still be required depending on diameter. I believe we discussed this awhile back, didn't we elane352?
