Please don't try the BBQ fluid solution! If you don't crack the block you
might hurt somebody. There is no "easy" way to do this. Maybe a machine shop
could rig some kind of a press but cost would be prohibitive. The pistons
WILL come out with the proper "persuasion". Set the block upright on a
couple of railroad ties or the like. Soak the bores with Kroil for a day or
so. Get a 16 lb sledge and a 3" driver. Knock the pistons down in the bores
and remove after breaking off the skirts.
