This has probably been asked a dozen times here on moparts. Forgive me. Which coolant thermostat should I run? I've not fired my engine yet.i have a 160° stat that the mopar guy at the local speed shop sold me but since then I've read information suggesting a 190° would be better.

Either the 160 or a 180 max... the higher stats are more
for emissions reasons
