I was going to ask the same thing. Those little heat guns are cheap and work great. I think they are still around 20 bucks at Harbor Freight. I check my header tubes, radiator, t-stat housing on my stuff with them. I agree with the Masses, it shouldn't be the gears. I ran 3:73's up and down the interstate for hours at a time without issue. I also don't think 200-205 is hot either... If your fan is flattening out at the higher RPM is won't push as much air as did before. I have experienced that with flex fans and tall gears. They would run cool around town but flatten out while flying up the interstate and my temps were higher then. Still, 200 isn't bad in my opinion. I do have large box fans in the garage that I run in front of the car with the hood open after hard drives. That's only because I don't like to watch the temps skyrocket after shutting off these old engines. I worry about cooking the bearings sometimes Hope I helped some.
