Motor was submerged and #3 bent a rod and broke a piece from cylinder skirt. Is block junk or would someone try and rebuild with this broke. Piston skirt is exposed .450”. See pics below!!

Can't really tell until you invest a little time tearing it down to see what the cylinder, crankshaft and other components look like.
 
Everything looks great. Cylinder walls still have hone marks and pistons all have the normal wear. Haven’t check crank yet but that’s next. Valves look good. Going to vacuum test when crank is checked for balance and deflection
