I need advice and help. I obtained a 454 LS6 4 bolt from a friend who overrevved the motor and blew a piston. I got the motor for nothing and tore it down to find that cylinder 4 piston complete exploded and broke out a 2" by 3" hole in the dead center of the cylinder wall on the side of the cylinder wall, which it appears it went into the water jacket. The bottom of the cylinder wall partially was damaged as well but not real bad. The rest of the block is fine, has a steel crank and the rods were all good. I know most people will say it is a paperweight but it is an LS6 motor and where I am 454 motors are hard to come by.

I did call a few engine shops who said they could sleeve the cylinder. I do not know much about sleeving, but my question is, can something like this be repaired/sleeved and my other concern is with this going into the water jacket will the sleeve seal this hole or will they need to weld the hold somehow and rebore the cylinder.

any good advice would be appreciated.
