340 Block Cost

I have the opportunity to buy a 340 block off a buddy. It needs a sleeve in cylinder 8 however. The goal is to machine & build this engine stroked to a 416. Any idea what the cost of the block should be if it needs a sleeve?
Why don't you contact the machine shop to get a price for the sleeve install and also have the block checked for any other issues? If you're buying off of your buddy he should have a price for the block unless he wants more for it then he paid for it.
