It is running hot all of the time. The gauge indicator is on the hot. I have replaced the hot water sensor. I have the 351 Cleveland engine. The engine is a rebuilt stock engine. The vehicle history is as follows:
I have had the vehicle for 2.5 years and it has always run hot.

The gauge may not be indicating properly which is why I asked how you know it is hot.
Does the engine boil over?
Have you checked the coolant temperature with a thermometer?
Is there a problem with the gauge?
The 351 Cleveland would not be a stock engine in your truck. The 351C was discontinued in 1974 (MY).

Ivan has a point but without a shroud, you would notice the overheating problem when sitting at idle or driving at low speeds. Especially when 4 wheeling as this works the engine more with not enough air flow through the radiator. At highway speeds, there is more air flow as the radiator is being pushed into the wind, increasing air flow through the radiator fins, thus cooling so it probably would run at correct temperature then.
I would do as torque says and invest in or borrow an engine thermometer to check the actual temp. Your gauge could be bad or the sending unit might be faulty. You may also have a faulty thermostadt from the shelf.
Just because you flushed the radiator doesn't mean there isn't some blockage in there that you couldn't get loose. This could be a problem as well.
Start with the simple and cheap things first, using process of elimination. Firstly, I would say, check the actual temperature with a thermometer.
Not to change the subject but Ivan, that is one nice looking truck in your signature!

hey guys i have a quick question, the past few days we have been getting hot weather locally, so i noticed at highway speeds my truck is running a little hot, about 10 degrees to hot, this is at 70+ mph below 70, it runs normal temp. when the truck is stopped in traffic or parked it runs about 10 degrees to hot. any ideas? this problem seems to defy logic.

pacochico, To the best of your knowledge,has it ran hot since the rebuild? ( I'm guessing it was done before you bought the truck) If so it's possible the same thing is going on that happened to a friend of mine many years ago. Had an engine rebuilt and put in his bronco and it ran hot from day one. Put in oversized radiator,changed t-stat,water pump etc,etc.
Several mechanics later he took it to our small town ford dealer, mechanic took one look and said "right there's yer problem" Turns out the shop that did the rebuild put the head gasket on backwards (not upside-down) He said he could tell this just by looking because the gasket has a small tab that should be sticking out the front.

Oh my gosh, what a bummer. I suppose that is a real possibility. It's amazing, I continually find where I would be better off doing my own work. You pay professional fees for professional work. Go figure. Definately one to look into Pacochico.
The nice thing about the old Fords is that you can do your own work, without a degree in electronics.

I always check the most obvious thing first....coolant level. Sometimes the tube from the radiator to the overflow tank gets clogged or the tube gets pulled out of the tank partially. Either way, if you don't check the radiator itself, the overflow tank might be fooling you into thinking you have proper coolant levels. Bottom line...check the radiator coolant level after the vehicle has cooled down for several hours, if not overnight.
