With a street driven automatic, I prefer a 180F thermostat as a replacement for the stock 195F unit. (Automatics don't like a lot of heat, and since your transmission fluid is cooled by the radiator, a 15 degree drop in water temperature helps a lot.)
If you auto-x your Vette or otherwise participate in sporting events, you might be able to use a 160F thermostat; however, depending upon where you live, your water temps may be too low during fall/winter to obtain full use of your heater/defrost system. I've only used a 160F in auto-x vehicles, and even then, had to change them out to 180F units during the fall in order to use the defroster in Virginia. YMMV.

The factory used 195 thermostats because their engineers understood that the motor needs to run that hot to burn off acids and contaminants that form in the oil if the motor is run cooler than that. Taking a look at OEM parts and procedures will usually put you on the right track as to why something is one way or another. Their engineers get paid the big bucks to figure this stuff out.
