It's preached here on a regular basis, but people still think the thermostat controls hot how an engine runs. That's mainly the radiator's job. And thanks @slantsixdan for chiming in. I was thinking of coming back to tag you but I didn't have to.
I normally split the difference on thermostats and go 180* on my stuff, but most of the time, you see OEM thermostats above that.
