340 block value?

Well that's all about as interesting as I thought it might be. It would be sensible to assume someone with the background of Jim Szilagyi (Mopar Motorsports small block Mopar race parts developer) should have the facts down, but I think we all know facts can be hard to pin down. Regardless I'm finding his book to be a very valuable and enjoyable read.
I do think I'd rather sonic test my engine block than the block on top of my shoulders :)
I'd get the number off the block but its not so easy to get at where its stored.
It's going to sit where its at since there's a small chance I may restore the car it came from.
Thanks for all the interesting conversation.
