Thoughts on Cooling a Stock 383 HP Barracuda/Dart.

When I was having problems with cooling before having the radiator redone I verified how the radiator was working by using an infrared temperature gun. Check the temperature of the radiator when hot from side to side starting at the top working down. Should be relative even across getting cooler as you go down. Doing this test shows how well the radiator is cooling and if there are any large differences/issues. Simple test that shows how the radiator is working.
