Stuck pistons/Crank, any ideas?

If you aint already, you might want to get a piece of plywood pretty large, to roll the engine onto so you have a nice place to work on the engine while you are beating on it :). My friends used to use used oil, used tranny fluid and desil mixed together in thirds, to unsitck motors, since you could make up a gallon or more of it for practically free. Then put that in an old dish-washing liquid bottle to squirt all down the cylinders and all over the place. That is called "hill-billy mystery automatic engine de-stuckifyer oil". It is patend pending.
