Problem solved after only 20 hours of diagnosis...... Defective oil pan gasket. The engine had the truck oil pan swapped for a Corvette one. The pan and the riveted gasket were used when installed. Apparently when the person removed the pan from the Corvette, part of the gasket either broke off or was stuck to the block. This is the rectangular area on the left rear side where the oil goes down to the filter. This area was completely open to the oil pan. Oil flowed down the galley and right back into the pan. The only reason we had oil in the filter was gravity. If you didnt know these engines at all you would never have seen this during the install of the pan.
