Still surprised with that.The 400 block is filled within 3" of the deck with hard block as well. The small block was only filled to soft plugs. I think the crank and intake on this BB is lighter, but not sure where the rest of the weight is or lack of. I'm very happy with the out come anyway. So the weight of the car only is 3200# with BB.
