i say its due to the body lift and movement of the fan shroud, your shroud is now 3"down from where it is supposed to be or has a 3" gap in it, nobody else has had this issue that i have seen. I too would get some ls1 fbody fans, sure it would entirely fix the problem. You have a bigger motor with high compression, that makes more heat than a stock 5.3, people don't realize that a v8 isn't a v8, more hp=more heat. And that watter wetter and such is a gimmick. it is good for drag racing because it isn't slippery and if you blow coolant on the track you won't be hated by everyone while it takes an hour to clean up. We have tried it in boss hoss bikes at work and it doesn't do a thing for lowering temps.

Remember, in your case, it's not just one thing, it's a combination of your setup, along with slowing down the fan & coolant flow with the UD pulley. The E-fans in the classifieds should cure your troubles, and give you a couple hp at the same time.
Don't give up and sell your pulley, get the Efans. You'll be glad you did.

Don't be so quick to condem your UD Pulley. I've been running one on a 99 for 10 years and the temp rarely gets above 185 unless I'm in stop and go traffic w/AC "ON" in the heat of summer. I installed Flexalite elec fans(one pusher and one puller and I don't even have a fan shroud). I used 2 relays to turn the fans "ON". One triggers off of the ECT and the other off of the AC clutch relay. If you use factory fans you can use the PCM as a trigger. I'd do the 160 T-Stat and elec fans and then see what happens. I'm also running a Meziere so maybe that helps keep my water temps down, but those things cost about $600.00 which may be a little steep to get your water temp down a few degrees.
