The LS motors were designed and built around a certain operating temperature. Running the motor too cool can be just as damaging as too hot.
Adv. to running a Lower T- Stat is being able to add more timing w out getting Spark Knock and the only draw back is losing a couple MPG
I dont see how it could Damage anything and have been using and installing 160 stats in my own cars and every other Ls Car in my town w Mods.....
