I wouldn't recommend a lower t-stat, these engines need to run at a higher temp to burn off condensation in the oil.

Depending on your location and mods depends on the T stat to use. The main purpose of the lower T stat is to have cooler engine coolant temps and increase spark advance (more power) with out KR.

My 160* works fine in ALL seasons. My heater works great in the winter too and my truck still gets to normal operating temps.

Yeah that would be a good thing to do now that your in there. Good luck!
It isn't the weather that matters, it is the engine temperatures. I wouldn't recommend anything under 180, if you feel the need to change anything,
By installing a 160* t-stat, usually, not always, you are going to get overheating. Now, I live in Arizona where it is hella hot in the summer. And by installing a lower degree t-stat, what is going to happen is my engine is going to fight to try to keep the engine cooler. What I mean is, by having the t-stat at 160*, it is constantly going to stay open there for the coolant will never get a chance to cool down inside the radiator with fans, and just keep circulating coolant constantly never getting the chance to cool down. By the t-stat not getting a opportunity to close, the coolant will never get cold enough to close the t-stat, and then overheating will accure.
I've used them on 4-6 cylinder vehicles with no problems, but never on the Tahoe, or V8's. I would like to know if anybody has done this switch, and where they live, how hot it gets in summer, and if it helped.

I have never had my truck over heat in the summer. It has gotten to temps up to 115* out here in th esummer and with the AC on it still doesnt over heat. With the proper efan setting you would be ok.
There is a lot of false info out there on the interwebz, we plan on doing a side by side comparison on the dyno with t-stats, much like we did with the CAIs.
