The oil level is WELL below the height of the oil pump. Remember the pump is bolted to the rear main. And the sump level is always lower than the crankshaft counterweights and connecting rods. So I would say the pump is about the same height as the bottom of the rotating assembly. Meaning the oil is a few inches lower. Enough to cause cavitation if you pull too much crankcase vacuum. The key point in every paragraph of that little novel was reliability.

dry sump pictures
Here are two dry sumps. They were made from existing pans. The windage tray is retained. The pan bottom is cut off to allow a lowered engine. The pickups are bevelled with a 1/4 inch bottom clearance. The pans are divided into front and rear sections. A remote three stage Barrnes pump is used. For a street application the pump bottom could be maintained. The dry sump tank is a Coleman unit with oil cooler.
