THIS 1965 HEMI IS FOR SALE. I WANT TO BUY IT.

Unfortunately the individual parts to the right guy would make that motor more expensive to buy than just getting new parts. I would make him price it, you can't sell it and buy it too. If he won't price it just lowball him for about $2500. Either you'll get a good deal or he will get pissed and tell you what he thinks it's worth.
