	My temp is measured right under the thermostat, and the car typically runs
right at the thermostat opening temperature, regardless of ambient temp.
	Gauge accuracy has been confirmed with a seperate thermometer.
	Engine is an aluminum-head Hemi style four.
	And I'm outta here...not wanting any argument, just offering my
observations for what it's worth.
