BTW: in the end I took the big electric fan off cause it was still running hotter than I liked and I put on a viscous fan and it cools better than the big electric fan. Your experience may not be the same, just sharing mine.
I appreciate the advice. I ran a MP viscous fan set up with no shroud and a C body radiator for the last ten years and was having similar results as j par. It always ran right at 180 regardless of the outside temp. Never even thought about my car overheating. Now it's in the back of my head. I've got to stop worrying/over thinking these things!
