Pulling the engine for new freeze plugs

Yea not sure what to do now.

Cylinders don't look to bad. I would like to use existing pistons but it does have a little ridge at top of cylinder. Probably end up boring but I will check with the local shop about clearances first. Might be able to get away with just a another rod, new bearings, and rering. I have another 273 for rod parts but I not sure if they all have floating piston pins like the commando engine does.

The thing that started the complete disassembly was I couldn't get the rope rear main seal out. Couldn't pull it out or push it out even with the main caps loose and lifting the crank a little.

Kind of weird the crack on the rod. Doesn't look like it was ready to break. Makes my wonder if the casting was bad from 1966
