junkyard 440 approx price?

That's what I thought they should go for I was just so awestruck and pissed that a guy would keep so much and not have plans to sell or build. I went to an estate sale last weekend and when I got there the same guy bought a line of a dozen or more mopar engine and more than that of 727s for pennies on the dollar and I had to leave empty handed while these engines are gonna go sit in a pile in his yard to rust up and be good for nobody. Thanks for the replies I am continuing my search
