230 casting 400 engine

He needs to answer the casting date question. If it's cast before 10/10/1971, then it could be a cold weather block.

Without knowing that, it's probably worth the bid right now + $100.

Josh, what was the asking price when on CL?

I had one of those cold weather blocks that had horrible core shift, needed 5 sleeves. Not such a great deal when finished.
When finished? Why wouldnt you just get a new block before having to have 5 sleeves installed? The block wasnt sonic checked first? If ya had problems after you built the engine why would you even consider using the same block? Makes no sense.
