What I've been thinking of lately would be a street/rat rod with a Ford flathead V8. They had top radiator hoses in the center of the head, so they could point backward (with return lines to the water pump under the headers):

It would have the '25 or earlier body with the narrow footwell with custom twin radiators with a remote top tank. The hood would be a bullnose plenum, the intake would be between the frame rails with vertical louvers at the A-pillar for exhaust.
It
could be in sheet brass like the bell of a tuba.
