Stuck pistons/Crank, any ideas?

I was holding my breath waiting for an answer. I thought I was going to hear I am screwed because the block is toast. This motor is slated for a stroke job and I was looking forward to it. The motor is sitting on its end but I have had it on its sides, upside down, you name it. How do I lift it? Grunt and groan. This PB Blaster sounds like the trick. It will be no problem to put the main caps back in. It'll be a week but I'll let you know how it goes. A million thanks guys
