whats it worth

[dukeboy_318]

My buddy has a 413 block that he wants to sell.  Its a 64 block thats is in good condition, probably woouldnt hurt to have it bored out.  I was wondering what are these things worth?

Not much, from what I understand, they arent very popular and you can still find them in alot of 70s motorhomes.  Of course I dont know much about them so I could be way off.
