power steering on 72
well just about got the ole 72 goin real good, got it running and ready for paint and stuff but the damn power steering doesnt work too well, my brother is actually doin the work for me while i'm here in baghdad, and he says it hard to steer til you rev it a little above idle, the truck sat for about 3 years before i bought it, i'm thinkin it may have a stuck valve in the steering box or some damn thing, what do yall think? weak pump or ?

yall all welcome, but as far as the power steering stystem goes i'm not sure if its a ford or bendix box, i'm pretty sure its a ford box because teh guy that had it before me bought it off a guy who had done some work to it, i do know that the headers i have on it fit damn good, and they said they wouldnt fit with a bendix box had to be a ford in order for em to fit, how do you tell the difference for sure between teh two? the guy i bought the truck from built it for street racing, with a 302 and an AOD in it with stock heads and an edelblock intake and cam package, but i gave that motor to dad which ended up being turned into a 347 for his fairmont, and i had a 400 going together for my 79 supercab 4x4 and said to hell with it since a guy in my unit offered to buy it once we got back so i put the 400 with a little more cam and some port work in my 72 with a c-6, i havent got to drive it yet but i am very anxious, dad says its a torque monster just pullin it in and out of the shop

Early in 69 was the last of the Bendix steering box, it has a 4 bolt aluminum cover, the Ford box has a 2 bolt cover made of iron.
You may have the slipper shoes inside the pump stuck not allowing for the pump to build up to normal line pressure.
The pump have ATF fluid in it to the correct level?

There is nothing wrong with that Thompson pump!
If it is not a whinny sounding pump you can rebuild it, get the proper pulley puller as well a kit that has a pump shaft bushing, cheaper kits do not have this bushing. The Can to pump seal is a known leak area.
The pump is easy to rebuild vs a rebuild exchange that can be worse than what you have.

Wonder if lifting the front wheels off the ground, and turning the steering wheel from left lock to right lock about 20 would help?
Have him lift the front just enough to clear the ground, crank the truck and do the process. Should it not clear the issue it will have only cost you the time it takes to do it.
This should clear any air that might be trapped.

You didn't steam clean or pressure washed the engine compartment allowing water to get into the pump? Steering linkage and kingpins free and not locked up? The fluid burnt and stinky?
The pressure regulator and bypass are in the closed position at rest so that isn't your problem.
I would gamble on a Pick-N-Pull pump at least you'll have two to work with, rebuild or a core.
