Ford Repair: 1985 F250 engine suddenly locked, high humidity, flywheel

Question
I drove my truck on too many times with a bad clutch. After having it towed home on a flatbed, I started to work  on it. When I tried to remove the flywheel I had to jamb a blade into the teeth of the flywheel to unbolt it, but when I went to reinstall the flywheel I didn't need to do anything. Once I finished the project and went to start my truck, the starter wouldn't turn it over. I then tried a break over bar on the bolt in front of the engine off of the crankshaft with the transmission in neutral and couldn't budge the engine. I bought a new starter and it didn't work either. I read somewhere else that not many things can freeze an engine other than a bad bearing or something breaking inside. I'm in Texas where it has high humidity and has rained a lot since my truck has been down, but the closest I got to the engine was replacing the pilot bearing in the rear for the tranny. Can you tell me from this if there is something I;I'm missing here that has my engine freeze between taking the flywheel off and reinstalling it?

Answer
I don't think that the engine is seized. I think that you installed the throwout bearing backwards, a common occurrence. A seized engine is a pretty big deal. Remove the transmission, which should be pretty easy, since you just did it. This time, have the flywheel resurfaced/turned after you find that you are able to turn the crankshaft via. the pulley. If you have burnt up that many clutches, the flywheel is long overdue for resurfacing.
