You need a fan shroud in order to get the fan to work. Without a shroud the air blowing out the back of the fan just curls back around into the front of the fan. The engine will overheat unless you get going at better than 30 MPH where the motion of the vehicle starts to push air thru the radiator.
Unfortunately sometimes the engine overheats even at cruise speed if you have removed all of those little baffles. Ya know those flaps that nobody knows what they are for...
Remember Ford didn't put any of those parts on just for fun. If a part is on the vehicle there is a reason!
Make sure you have a minimum 180 t-stat. A better choice is a 190+ stat.

Sean,
What kind of tranny do you have?
Is it shifting OK?
Do you have an auxillary tranny cooler? The auxillary cooler are more prone to clogging and thereby burning up the tranny. This, in turn, causes the motor to overheat do to excessive heat rejection to the radiator.
An Automatic tranny can create alot of heat when in poor condition.
If this is a problem, it may overheat, as quickly as, four minutes from start up, or it could just slowly overheat over a period of an hour or more.
Do you have headers? Are the cooler lines laying across them? This is another one that people overlook.
Consider it,
KingFisher
