Found some HEMI blocks

My brother found 2 Hemi blocks and 4 sets of heads yesterday. As far as
I know the guy was a mechanic for Dodge in the 60's. My brother does
not know too much about Hemi's, the guy told him there date coded
68 & 69 model year. He also gave him some cranks and rods. One block
still has everything in it the other is bare. What's all these parts
going for these days? I told my brother to hang on to all of it until I
come out and see it. I want one block and heads for myself.
