Hola Ropat:
A second, and slower, look shows that the car could not be FWD as I suggest as the "housing" I was thinking might make it FWD is too low in relation to the centre of the axle.
As to the engine type, I agree, of course, most of the hot rods of the day were flathead V-8 powered but again, the engine compartment is pretty narrow and there were quite a few 4 and 6 cylinder rods as well.
So, more guessing. Good Luck!
Bill
