Freeing up a frozen block ??

I should have mentioned, this is a short block. I'll rotate it so one bank of pistons is up, and give those a soak before doing the same to the other side. I do have it on a stand. And yes, sir j par, this is an exercise in "how does that work". The engine is going to the scrapper when done.
You sure you don't want to wait until you're handed that numbers-matching Hemi Daytona to figure this out?
