This might be a stupid question. Are the oil pans able to be reversed front to back? I've noticed that AMT's (ancient) '57 T-Bird kit uses the oil pan with the flatter portion of the pan to the front of the engine, while passenger car '56 and '57 kits use the taller portion of the sump in the front. Crossmember clearance?
I'm not any kind of Ford engine expert, obviously. Nor am I a mechanic.
