Stuck 440, Need Help !!!

Almost any cylinder can be fixed. The question becomes is it worth the expense. I've had a car drag the rear tires with a 440, hemi box, and Dana 60. We dragged it back and forth, dropping the clutch trying to get it free. Know what was stuck? The oil pump drive to the bushing in the block. I buy stuck engines as cores lot. The prices are always right...lol. Some tricks...use a steel deal blow hammer and rap the tops of the pistons (that you can reach) on thier north and south points. Pistons normally rock in the bores in that direction, and this will free up rings that rust to the bores, and will help loosen up the pins that corrode onto the piston pin bore. Then spin over the engine stand, and unbolt any rods you can reach. You are rebuilding it. So things like rod bolts will be replaced, and pistons will be replaced. Do not hit the rods if you plan to re-use them. I use an old strut rod placed either on the bottom side of the piston's dome, or on the flat on the bottom of the pin bore on the piston and hammer them out. When you're done, have the block airless shotted after degreasing, and you'll see how bad the bores are in terms of rust pits. Then you can tell how much using that block will cost.
