Actually, it would be very simple to get a wider modern truck radiator and mount it right behind the grill, if you wanted more room in the front of the motor. The sheetmetal contour behind the grill makes a very nice start for a fabbed-up fan shroud too.

That's what I plan to do when I convert to a V8.
