Just personal preference, but I like the looks of the 60's Ford style tri-power/dual quad aircleaners. PAW sells a close copy of them for about $50, but only with a single 4 BBL or dual quad base. Fabricating a new base is not really much of a challenge though. Also check some of the off road places as they sell a some of the smaller aircleaners with offset bases that will clear when oriented right.
