Travis,
Before you panic, get your timing and fuel mixture set up properly. There is
no better way to make an engine run hotter than to have timing and carb
settings out of whack.

Re: followup - good operating temp and thermostat questions
I know I'm arriving late to this party, but my Rubi, and indeed all 2003+
TJs run at 210. No matter if I'm cruisin' on the highway, stuck in traffic,
or runnin' AC on the trail (for shame!)

Re: followup - good operating temp and thermostat questions
Hi Chris,
The stock cars are running that hot, not because they want too, but
the running at near full throttle just generates heat, more heat than
they can control, with their stock body design restrictions and the
spoiler trying make the car weight three times their weight in down
force. Making nothing extra for the driver, leaving him with just a hose
vented to the outside to cool himself. I would be very surprised if any
race car ran a thermostat, just another restrictor plate:

If you had a Corvette LT-1 you'd want an 160 degree thermostat:
