Got my truck back from the local hotrod shop. Had new leaf springs installed (lowered 3") and improved the ride immensely. Plus, the main work done we changed out the fan (electric, and no shroud) system with new fan (with control module) and shroud. Changes to cooling were amazing. To give you an idea of the changes we'll use the following. Outside temp in the high 90's (97 degrees this Saturday).

Old system would run 195 degrees at 70mph, then in traffic would climb to 205-210 degrees (making me very nervous). With the AC running (which we would have to turn off, making my wife uncomfortable).

New setup, with the same outside temp, now runs at 185 degrees at 70mph, then in traffic drops to 170 degrees all with the AC running. AC actually is colder as well. New fan blows like a hurricane pulling so much more air through the radiator.
