can't understand it......
Ok, this one's got me stumped. I went out to pick up my horse trailer today and the ole 400 was running a little warm, high M on the TEMP gauge. Hooked into the trailer (16' 4 horse slant bumper pull) and everything ran perfect! 
the temp dropped back down to E and never moved. Even pulling hills at 55-60 mph she never missed a beat. I'm not complaining...just curious Any ideas?
Thanks!

Ford gauges are goofy.
As long as the coolant doen't blow out of the rad,Don't worry about it.
When I first got my truck it did weird things like PIN to max ,then after 10 minutes and a bump slowly returned to the center of the gauge.

Airflow can have a dramatic effect on cooling. If you drove 20-30 mph to pick up your trailer, and then put her out on the highway at 60-70 mph you might have explanation. This would increase especially if you aren't running a fan shroud.
Just a thought. Take it for what it's worth.

The speed stayed the same, 55-60 empty and loaded. And I'm running a shroud. Just did bearings, timing chain, and hv pump so oil pressure/temp shouldn't have affected it.

Could it be that the thermostat stuck? Then it released? Might be wise to go ahead and change it just to be sure.

I found a piece of crud (scale/mold flash) blocking my thermostat once...
You can also rejuvinate those old Ford gages by cleaning the flex circuit then using some dielectric grease on the contact points. They will work like new then
