I recently purchased, but have not installed, a 160 degree thermostat for my 96 Trans Am. I also plan to get my car tuned and set the fans to turn on about 180 and 195. My question is that will these lower operating temperatures cause too much carbon buildup in my engine. After researching this mater I am thinking that I might just go to the 180 degree therm with the same fan settings. Anybody have any knowledge about carbon buildup? Also, doesnt the engine run best around 180?

 

put a hypertech 160 in my lt1 no probs . actually runs better due to little to no heat soak in the intake. the temp runs at 170 at all times.im happy with it!
