What is a 340 block worth

Nothing. I'll come pick it up so you don't throw your back out putting in the recycle bin.

Too much any more. There are some well wishers out there. I saw a complete 69 340 with matching 727 for $5k. It was sitting in the bed of a shitty old truck with a tarp over it. Seen a guy asking $1k for core X-Heads, because we all know how they are better than all the other 340 and 360 heads....
