Well I guess that depends on what you are going to use for a rear end? I don't think that the original rear is going to be up to the task.
I've got a 63 Pontiac 9.3 inch on the axle rack, most likely candidate to replace the rusted bangedjo Yeah, I know. But I dream of both the sheer terror and lip-ripping grin that a Model A with a 392 Hemi could bring. When I get started on the frame, it'll be built to handle the Hemi. A flathead Cadillac and the Chrysler have surprisingly similar motor mounts on the sides of the block. Hmmm, seasonal motor change?
