Wow, 160K. That's not even half it's life. I'm like the others, theres probably something going on otherwise. I wouldn't think that the motor needs broken apart with only 160k on it.
The crank will probably be very hard to turn due to compression. Someone correct me if I am wrong, but I think these things run at about a 13:1 ratio.
Like someone said in a previous post I would start with the starting system, you will have to have that even if you do a rebuild, then go from there. I feel like once that is done then you should find that the motor will turn over.
Unless someone has treated this motor really bad and filled it with water and let it sit or something. You should be able to get it running.

if the truck has been sitting a while I would drain the tanks and replace with some fresh fuel just in case there has been some water in them . Before I started trying to crank it I would also bleed the fuel filter housing just to insure there wasnt any water in their either . Make sure both batteries are good . The 7.3 psd needs a lot of juice to start and the injectors require at least 10.7 volts to operate . My guess about the previous owner saying it has always run funny would be the cam position sensor . Ford had a recall on them a few years back and will probably still cover your truck if hasnt already been changed .

WOW....didn't realize that the compression ratio was that high. It may take a really big breaker bar to rotate that crank.....

How hard should it be to turn it cuz I thought that it didn't take a lot of strength, and I used a cheater bar that wasn't big by any means.

yOU SHOULD ENCOUNTER SOME RESISTANCE, WITH A CHEATER BAR IT WILL BE easier. You should not have to huff and puff to turn it over.

no kidding
I'll replace all flueds, including gas, and filters before I start the thing. I think the first thing I'll do is make sure those batteries are producing enough juice, than I'll see if the starter is getting enough, than go from there.
