I live in western Canuckistan. Far from a plentiful supply of cossie blocks. sure I could troll the boneyard for a very rare Pinto block, but it would just be a pinto 205, not a selected block.

I have a spare block but it's cracked between cylinders. Chuck it or should I save it and if needed in the future, sleeve it?

I just have a hard time chucking a cossie block that cost a wad of $$$ to ship here.
