I'd suggest pulling off each main bearing cap one at a time to verify there's not a bearing failure going on. If there appears to be none, re-install the bearing caps, rotate the block back up, and mix up Jerrys famous elixir and let them pistons soak. Wrap it up in cellophane or other plastic to keep the smell down and reduce the evaporation of the acetone out of the mixture.

Let it sit for a few days and then try Jerrys method to rotate the crank using the flywheel.

I think its very important to eliminate main bearing failure and or if possible rod bearing failure prior to attempting to move the crank.

I suspect the most likely scenario is the rings are stuck to the cylinder wall as the cylinder wall appear to be rusted. Soaking with the acetone / trans fuid mix will help a lot.
