Wow, I hope you at least bought your friend lunch that pointed you to this booty of parts.
A couple of years ago I found a guy in the local NM newspaper that had a large shop\barn on his property that contained dozens of FE blocks, 390's, 428's, 427's - heads, original headers, 3 deuce intakes, dual quad intakes, cranks, etc. He had 30 toploader trannys. You name it, he had it. Then I started asking how much he wanted for say a toploader - he wanted $1800 for one that needed rebuilding! He was literally more than double on what any of it was worth, and he wouldn't budge a nickel. He was an elderly guy and he would chuckle and snicker as he talked prices. I honestly don't think he had any intentions of selling any of it, he just want to make people drool.
He'll kick the bucket eventually and all that stuff will probably get hauled away by some junk metal collector. It's strange to me, I'd want to know that the stuff was getting put to good use somewhere. Sad.........
