Stop in for a cup of coffee

Never tried that....Does it really work ?
I have heard it does. I would think you could drill a hole in the piston near the bore and die grind or saws all toward the bore. If you relieve the pressure you should be able to pound them out. Getting the crank out would be the trick. I got a 273-2 from the same guy and I was able to get the crank out with all the pistons stuck.
