Thermostat or no thermostat?

Just rebuilt my 318, is a thermostat needed in a warm climate? Will the engine run cooler without the thermostat any difference? Appreciate your thoughts, thanks.

I use none in the summer--like right now, ha ha. Motor still warms up quick to around 140--150 and then hangs out around 160--170 once you are driving it hard. No worries last summer in 90 degree heat, even at long red lights.

I recall when my local PD used Mopars in the mid 1980's, their engines idle at 140 degrees forever. Bet they had no T stat either. I knew cause they had after market gauges and the water temp was a 5 inch gauge right in the center near the pd radio...

The last thing you want is a stuck close t stat in hot pursuit, ha ha

Anyhow, I got 4,500 miles on my 340, most times it has no t stat and motor still is nice and tight, burns no oil and runs great and I sure don't baby it...6,000 plus in top gear its done many of times
