Looking at the pictures, it does look like your block has the dual bolt pattern(try to get a pic of the back of yours) while the other one is the single bolt pattern. From the pictures it looks like your bellhousing uses the later bolt pattern...which means that earlier engine will NOT bolt up to your transmission(notice in the pictures of the 65 engine the bolt holes are several inches from the deck while your bell is bolted up right below the deck)...on a side note...your bellhousing WOULD bolt up to a v8. Too bad you aren't closer, then you could take my dual pattern I6 that came out of my car off my hands. One place you can try is search-tempest.com. Its a craigslist search engine that goes by distance...lets you easily search craigslist over the entire nation or just within x miles. Another thing to consider...you could always upgrade to a 250CI I6...not sure what is involved, but those engines are pretty common, being used in Ford trucks all the way into the 80s
Too bad you couldnt pick this up...its the holy grail for I6 guys:
