Ok so i got a stuck 350 engine. head is off, pistons exposed. left side cyl, free. right side piston is holding on for all it is worth. it is soking in PB blaster (not peanut butter), i scrape all loose crud from around the piston/cyl, whack a few times with a rubber mallet just to get some molecules moving, repeat a day later. what other types of voodoo spells have yall had to invoke to get pistons undid? heat, pressure, violence? i am up to suggestions

Thanks for the replies so far, let me lend some more info. the engine was siezed when it came into my possesion. due to the looks of a cam lobe or two and some rocker faces, oil starvation may be the culprit, i have not inspected all of my passages yet. I do intend on a bore job and over sized pistons so a chisel is not a terrible idea. FR, the crank does rotate at least a little. it is stuck pretty darn near TDC because the cyl will only raise up a little when a turn on the crank. i think that if it were stuck closer to the middle the cylnder would travel further up and down both CW/CCW since the other piston is free. you know, as one unit. This brings me to bmartins suggestion not to apply too much force in regards to the rod or bearings being damaged. if the rod was at more of an angle any force i would use would be move the crank down and around. if it is as near vertical or TDC as i believe, most of that force would be going straight down, through the rod to the bearings....uhh, maybe i will stop wacking it as much
