BillyBob, THAT thing is going to be a CHICK magnet when you get it running and driveable! A good mechanic I know that does these old vehicles for a living told me that one of the best 'rust cutters' he's EVER used for loosening slightly 'stuck' pistons in those old six bangers is.... BRAKE FLUID!
Good old cheap-[censored] k-mart brand brake fluid. Let THAT brake fluid hang in those cylinders a day or two and then try spinning that motor over. Now, if it breaks loose and spins over, you will want to change the oil pretty quickly after getting it to turn (brake fluid is NOT a good lubricant and will hurt your engine). Give it a shot, maybe it'll free that beast up! Good luck! randy
