Cracked block on 1922 Single Six

My 1922 Packard 126 Single Six Tourer has been running badly this season and has been getting water into a cylinder. I have had the head removed and there is a crack in the block, running through the valve seat and down the bore on number 3 cylinder. This can be repaired, either by welding and machining, or better by welding and then boring it out and fitting a dry liner, but we are not sure whether the block has enough metal there to stand machining to take a liner - advice please! A good alternative would be to get a new block, but I guess that there aren't any available - does anyone know of a suitable block which I could buy? The haed was also cracked, but on the outside of the water jacket, so it was weeping water - this CAN be mended by welding, so I don't need a head, but one would still be useful!
