Good thoughts Poly. On the 65 k member area, there are two areas that together make up about a 2.5 sq ft parachute! If i fill those in with thin alum., the deep pan remains fully exposed to air flow but the bottom of radiator core support to k member now directs air down and back towards oil pan. I think it will work, look nice and clean up that air path from a catchment, turbulence area to useful airflow.
