How to force pistons out of 383

Update: tried bfh and 1/2" black pipe after it sat in MMO, no luck freeing it. I dont know at this point what im doing, im going to check and see if a friend can bring his torch so I can cut rods and lift crank, then im going to get a 4x4 and hopefully beat out the rings

That block is likely junk.
What im thinking, just happy that I can salvage what I can, timing cover, valve covers, water pump housing, rockers, pulleys, brackets, motor mount brackets, alternator, distributor drive gear, yada yada. I think i pulled away over 300$ worth of big block accessories at least. At least compared to what i could buy new, just needs soaked and painted. Just amazes me how the outside looked as nice as a complete engine that sat for 10 years can be, yet the pistons are THIS STUCK. Maybe its a sign to get a 440 after all haha, this time I'll go with a BARE block to not have to do this mess again. Not like im using anything else.

Doesn't mean im not going to try and get these pistons out

Well, title kinda says it, soaked cylinders in MMO for 2 days now, getting impatient as I want to get the ball rolling and the block off to machine shop soon. You guys know how long they take, so sooner out sooner back, and all 8 pistons are in it frozen. Tried air hammer on both sides of the pistons, hammer hammer on wood, big breaker bar, nothing. As referenced by air hammer, dont care about piston and rods, just want the block and preferably the crank. Leading theory in my mind right now is torch/cut out the rods, drill a hole in piston, and give it love with air hammer
Should I be worried though about melted rod hitting my block and messing it up?
I know it sounds crazy, but I have used coke cola as a soak many times with stuck pistons. It has always broken loose for me. I don't know why but I think the coke tales care of stuck rings to bore, but as I said, it has worked probably a half dozen times for me
