Started stripping the block today. Found a lot more pieces of the piston and the reason the cylinder wall cracked. Not pretty You can see how the washer just crushed through side of the piston The force of the washer crushing through split the skirt off and must have thrust the piston sideways into the wall. The pieces of the skirt I pulled out of the bottom of the motor.

The good news is if I can find a shop that can resleeve the block for #7 near Bergen County NJ I should be able to rebuild it. Anyone know of a shop that can resleeve this for me?
If you are going to re-sleeve it. Then go big bore and do the whole block. You can find good used LS1/LS6 blocks for around $500. If you want to stay stock I would go that route.
I guess nobody saw the my last post regarding this motor, sorry about that. I have a 403 being built by Lingenfelter on the way. I want to put this motor back to stock so I can run it in my truck. If I can get it resleeved fairly cheaply and get a new piston all else is fine. Not going to build it for high power or rpm's.
