1973 340 price check?

I just bought a 440 that’s apart. The block was square decked, bored, Torque plate honed. Lined bored for new billet mains. Cam bearings were also installed. That’s over 2 grand right there. There is many ways to rebuild an engine. It all depends on how far u want to go with it. With no proof of what’s been done it’s a gamble by seller and buyer. U may not get enough for it, the buyer may get a good deal or a great deal. As long as both ppl are happy it’s a win win. Kin
