well..... if there are problems with the block, ie: bad piston rings, scarred piston walls, bent rods, etc, then you need to figure out how much you will want to put into it. $250 sounds like a decent deal to me, as long as the block itself isn't cracked. if that falls through though, I do also have a gsr block for sale. aproximately 100k miles on it. ran great when I pulled it. I'm asking around $500-$600 for it in good condition.
