But, looking at the photo= , it's the "U" labeled "Oil Cooler" that is showing a pressure differential and the radiator showing little or none. An older photo?? I presume this photo does not go with the words of your finding??

I did a lot of trial and error then finally decided that instrumentation was needed. I made myself a simpl= e manometer to measure differential pressure across my cores. As it turns out= , the radiator installation has about 4" of differential pressure on the ground at WOT; however, my oil cooler indication was ZERO differential pressure under same conditions. My suggestion is make some measurements ... a manometer is a tube with colored water in it with a U-Bend to trap the fluid; run one end of tube to a location infront of core center and the other end to a location behind core center ... this will tell you a lot that you simply cannot guess. ... attached is a sample picture of a manometer.
