Ball hone?

Honestly, find another core and build the stroker you planned on.

A ball hone is not going to clean it up enough and i wouldn't put any money into it without fixing the pump housing sealing issue.

Sorry, just my personal opinion.
I’m definitely going to find a different block for my stroker. I just hate to throw this block out, but I also don’t want to attempt to fix the broken piece. I don’t think it would be a sealing issue because the hole doesn’t go into the cooling system, and there’s still 2 bolts for that side of the housing to bolt to. Only issue I see is bolting a power steering pump to it. I have a manual steering truck that it could go in so I’m just trying to find a reason to use it for something.
