Dont force it to turn over. There is a good chance that you are lucky and no damage was done to the rotating assembly. Flip the motor upside down and pull the oil pan. Loosen all the main bolts and every rod that you can. Now try an bar it over to disassemble. I have worked on a couple of motors like this and had no permanent damage. One had an oil leak and the idiot was adding oil to the windshield washer fluid! Got the truck for free because of the locked up motor. Did the above and never replaced a single peice. Bolted it back together and ran that motor for 5 more months in 120 weather without issues. I have a small project v6 that was locked up by the owner running 40wt oil in it. Came out in 20* weather to start it and only got a click. Tore it down and there was zero damage. That one will get a full rebuild one day before sliding it into a new ride, even though it is fine.
