cost of engine blocks

I haven’t had a person around here come down any less than $700 for a rusty crusty high ridged 340 block. The best deal I have ever gotten was from a member here @rmchrgr
(The Great Pumpkin - '71 Duster)

(Thanks GREG!) where I did get the whole short block 340 for $700.

400’s go for $100 - $250. Greasy!
440’s? IDK
