Ok, I ordered a new radiator. This one for a late sixties to early seventies ford truck with chevy conversion. 3 core, much larger core area and 2 12" fans rated at 1300cfm each with a louvered shroud. Rated at cooling 600 HP. Going to change back to the sending unit for my gauge and see what happens.
Also tried to post pics,,,guess I'm not smart enough.
Thanks for all your advice. I well keep you informed after the radiator install.. Or if your close to middle Tennessee and this don't work, you will probably hear me.
