This is a 428 block, I assume? The block doesn't have as much value as a passenger car block, but at standard bore its still worth some money, I sold quite a few of them at standard bore from irrigation engines at around $900 each. Not sure what the rest of the stuff is worth, but an SCJ reciprocating assembly ought to be worth something.
By the way, I moved your post here because questions about the value of parts are supposed to go in the Classifieds section. Thanks, Jay
