  Was it seized from rust or seized while in daily use?

  I don't know if I would recommend the above, for the reason
that the violent breaking loose could also release shards of
piston, rings, or cylinders, that would then go on to destroy
whatever is left and make the rebuilt a necessity.

  Generally, the procedure is to remove the block and let it
soak in penetrating oil or similar for a long period of time, like
days or weeks. Then you can work the crankshaft gently to try to
dislodge the pistons, then clean the bores, and put it all
together again.

  If for example a ring is melted to a bore from overheating, snapping
it loose with the starter might break it off, freeing it to
destroy an otherwise reusable bore.
