I'm thinking full-fendered A-V8, just like one would have been built from '45 after the war through about '53, including the then-hot setup '34 X-member, 16" steel disc wheels, recapped slicks, 3-speed LaSalle or Packard gearbox behind a "full race" 8BA flathead, Halibrand 201 V8 quickchange (which would make it post-'48, I believe), '40 Ford "juice" brakes, and a dropped-and-filled front beam axle. Yeah, that'll work.
