siezed 440
Had a 400 stuck real bad like that. Soaked the cylinders for months with trans fluid with no luck. Flipped it over , took all the mains off and drove the pistons out from the bottom. Unfortunately most of the pistons were scrap ( I did not need them anyways) I think maybe a rod or 2 may have been damaged. I also did not need them. But it came apart in about 15 minutes. See pic below for aforementioned block. fastback383...
