Below are pictures of the clutch fan set up If you look at the first photo and towards the bottom of the photo you can see how much of the fan is still out of the shroud. In the second photo you can kind of make out how far the fan blade tips are from the ID of the shroud opening Now interestingly enough I contacted Hayden (the company that made the clutch I have) about my issue and they say to use the original fan that came on the truck with their clutch. Well that was just a five blade fan (I put another 7 blade mopar fan on). So maybe, just maybe, the 7 blade clutch fan pulls "too much" air through the radiator (if there is even such a thing) which is causing the cooling system to go bonkers. So in the mean time I put the fixed fan back on for a road trip I am taking since that set up works as long as the truck stays moving. I am going to dig the 5 blade fan out of the parts shed when I get back to my parents place and install that to see if that makes a difference. According to a truck site they claim the 1 row aluminum radiator isnt enough to keep the truck cool while stopped with the a/c on. So a bigger radiator may be in this trucks future.
