cooling system

Not trying to jump into the middle of something, just trying to help. Being an old guy we learned how to figure out cooling problems on our hot rods in the 60's when we did not have all the pressure testers and stuff you have today.

It can only be one of two things. First air flow, second water flow. If your car is only running 200 degrees, that is not hot, just starting to make horse power at that temp. Take it our to a road where you can run a constant speed for about a mile or so, and be able to pull over.

First get it up to temp, drive at about 45MPH - depending on your rear end gear - you want to pick a speed that you can shift down a gear and maintain that speed - if it heats up while driving at a constant speed in high gear, shift down one gear and see if the temp goes up or down. If it goes up then you have a water flow problem, if it goes down, then you have an air flow problem.

I have used dual electric fans, and have not had good results until I built a schroud for them. I think either way a schroud takes all the guess work out of it.

Sorry for the long reply.
