Is this 408 worth it?

I have to agree with moper if you want more power than what your current motor has then put that $1000 into it instead of buying a unknown motor. For all you know he has a actual stroker motor that looks nice, but what about the cylinder walls and other internals you can't see. If he has numerous receipts and a lengthy summit account summery then why isn't he wanting more out of a number matching truck with a built motor. Plus if he needs to pay bills then why is he willing to trade?
