IMO $600 is way too much for that motor. It should be no more than $200-$250 because the motor is apart and will need to be put back together. Save your money and get a good running motor out of a 88-93 mustang, thunderbird, truck, lincoln, and so on. I sold a very good H.O. motor that was apart and needed new rings (didn't need to be bored) for only $150. Just keep looking and a good deal will present itself.
With the machining already done and all the fittings you are getting a good deal at $600 but it is Or Best Offer so offer $300 and see what he comes back with.
