This block has billet caps and pin oilers. The connecting rod on cylinder 5 broke and took a small chunk from the bottom of cylinders 5 & 6. The number 5 cylinder has a gouge in it, as shown in the photo’s. This cylinder will probably need a sleeve or a good cast iron welder can repair it. Cylinder 6 can be run the way it is or it can also be sleeved if you are worried about the chunk missing from the base, depends on the stroke you will be using. The pan rail next to cylinder 5 also has a hair line crack but does not go into water or the cylinder and can be run the way it is or repaired.
