If you can get it for $150 then that is a good deal. Any Mopar block is a crap shoot. You won't know if it is any good until you get it all apart and over to a machine shop. That is why you shouldn't pay too much for a block but $150 is a good price. If it is a complete engine then you can probably sell the heads and recover a little bit of money. Other stuff isn't worth much, maybe sell some brackets or pulleys or something like that. Everything else just goes in the scrap bin.
