1970 Boss 302 Block ID

[1969camarors427]

I was talking to a guy who said he has a 1970 Boss 302 block, He got it from his friend over 25 years ago. The guy said it had spun a rod bearing which damaged the crank. He has the block, 9 con rods 7 pistons, all the valves and a few other pieces of the engine, just small ones he said. The casting number on the block is D0ZE 6C15B, the block is STD bore. The other numbers on the block are 9K14 which i assume is the date code, it also has a 19919 and JK29 on the block.He said it was a 4 bolt main with screw in frost plugs. I have no idea what all these numbers mean, so i will ask all you Ford Gurus out there for some help on the ID of the block. He said it was from a 1970 Boss 302 Mustang. What are these parts worth if it is a real deal. He wants to include with a trade on some other parts. Thanks for the help.
