Motor plate questions.

our iron head 360 and our W8 engine both have 1/4 motor plates and no mid plate, but both engines are set up with a fore/aft brace from the block to the frame. We have the car set up to swap quickly from one engine to the other so everythings been built around that. Until the floor was cut out to accommodate the CSR shield, as I was making the car 9 sec legal, it would have been a bear to remove the trans with a mid plate set up imho. Torque converters can be made to accommodate the thickness of the midplate.
