225 Slant 6 Engine in solid running shape

Well, my project hit a snag. Apparently the previous owner winterized the cooling system with H2O ... and pulling everything off revealed a cracked block in my otherwise good motor.

I would rather not have to get a motor that needs a rebuild ... my labor costs at the shop are already steep. I have a line on a 'new' motor ... but hoping someone has a nice pull that they are willing to part with for less than the new one.

I don't need tranny, intake/exhaust, carb, etc.

PM with any suggestions.

THANKS!
