Is there a better way of doing this then continually smashing at these ? have to go through the top - the crank is stuck in place.

What engine?
I don't think pistons can be taken out thru the bottom on very many engines.
Pour some Winter Green on top of the pistons/around the rings, let it soak for a few days, pour in more Winter Green as it might drain away past the rings.
Turn the motor upside down, pour in more Winter Green, let it sit for a few days.
Then pound away from the bottom.

383 RR 69 - I could swear I took the 392 pistons out through the bottom - it was years ago - I could be wrong

I had to break the pistons out of a 440 that sounds similar to your situation. It takes awhile.......big hammers and chisels. Not fun!!!
Start on the worst looking ones. After you get a couple out you may be able to turn the crank!

Drill multiple large holes in the pistons to make it easy to bust them out. Once they are out you can concentrate on the crank.
Careful, your character's showing!

If your going to send it out to be rebuilt, why not have the machine shop do it? Yes it will cost money, but it may be better than damaging it trying to get them out yourself.
