Thanks guys. I'll wait to see the pictures he sends. He says it's date coded a 56. If that is the case, and it's full flow then bottom line, it's been modified. Hopefully it's just a miscommunication, and it is in fact an unmolested block. He has an 848 head I'm going to snag as well, so I hope the deal goes well. I guess even if the block isn't what i'm looking for, I can still get the head. I think he's selling them seperately.
