I would take the oil pan off and see if you can disconnect the con rods from those two pistons and see if you can then spin the crankshaft.

A long time ago my father and neighbor and I unstuck a Kawasaki 400 S3 motorcycle that had been left sitting behind an apartment building for 20 years or so, by taking off the head and, using a wooden block that was placed against the piston crown, hit the wooden block with a small sledge hammer and dislodged the pistons. We didn't disconnect the rods (roller bearings). Those cylinders were Nikasil (sp?) or somtehing like that, and the thing only required new rings and ran and ran until we sold it to some collectors for what now seems like a pittance.

Whether this method is applicable at all to a Packard I leave to the opinions of the experts.
