Trying to figure out how to get my power steering pump belt lined up with the crank pulley. As you can see in the pics, the p/s pulley sticks out a little farther forward which makes it squeal loudly on start up. Is there any way to adjust this? Thanks for the help.

Pulley is pressed on to the shaft. Possible someone had it off at one time and didn't press it on far enough. By the looks of the pulley someone tried to use channel locks or pipe wrench to get it off.
From where you stood when taking the picture you see 3 alignment bolts positioning the pump, plus one nut on a long bolt that pulls the pump and pulley and tightens the belt. I loosened all three of the short bolts (yours are nuts, mine are bolts). then I tightened the one on the side that tightens the belt. This should spin the pump slightly, or maybe you could shift it by hand. You want it to spin clockwise when seen from above. And then the belt pulley should aim toward the crank pulley more. And if it does you can tighten the other two bolts I had to do this procedure a few times and then I ended up with the pump pulley aiming at the crank pulley. Not even with, not parallel. but aiming in a direction that worked.
Squealing momentarily after start-up is usually the alternator belt, rather than the power steering belt. Especially after installing a more powerful alternator.
So check the tension on your alternator belt as well.
Regarding the alignment, work with what the others have already said. I would definitely check the pulley on the shaft, but look for any spacers on the back edge of the bracket (between it and the cylinder head) and see if that would help too. Some engines used the spacer, some did not. If someone added it to yours by mistake, or perhaps changed pulleys way back down the road they may have caused the misalignment.
Unfortunately for us, Ford has used so many different pulley arrangements with different sheave offsets, that it's hard to always match things up if they ever get changed.
The alternator is often the easiest to tweak, so if you need to change the other stuff to work, you can re-align the alternator with relative ease.
But since they're already lined up, and the pulleys look to be original (just an assumption though) then grab a P/S pulley puller/installer tool and see what can be done that way.
The suggestion by ford390gashog to post the numbers would be my suggestion as well with the year/model/engine in your truck. I agree that it looks the wrong pulley. With all of the junkyard part swapping that happens it is quite common to end up with a pulley that has the wrong offset. Ford used many different power steering pump pulleys.
I have a 390 from a 1976 F250. I had several power steering pumps & pulleys in my shop and none of them lined up correctly. I could have cheated and tried using the wrong pulley by adjusting the pulley location on the shaft or even put the pulley on backwards (ugh...lovely...I've seen it done) to get the right location. In the end I located the correct pulley which was stamped "7AA" and installed it correctly on my pump. I don't believe that all FE engines used the 7AA pulley but it is very commonly used on the mid-70's FE engines. For example, my 1970 360 required a different pulley.
Thanks for all the suggestions. I loosened the three lock down nuts along with the tension adjustment nut and then moved it around as much as I could to get things more in line. There wasn't much leeway, but I was able to get it a little bit straighter.
Next I will check on that pulley # and see if it's the original part along with looking for any spacers on the bracket.
@1TonBaseCamp: I'll check the alternator belt tension as well. It does make more sense that it would be that belt on startup instead of a power steering pump that isn't doing much yet.
I will update as I get it worked out. I'm finally getting around to having some time to work on things after moving and getting settled. This forum is always a big help.

what size belt did you use? I bought a 53.5 off rock auto and it’s too short
