I have a full set of the smaller KB 4.630 OD sleeves for less than 1/2 price of new. The are 4.320 ID and they are in good shape and stroke clearanced. If someone wants to buy them and send them to make there block complete, it's a done deal. That can get at least one of the blocks going. Go to racing junk and put KB sleeves in the search bar. I also had them here in the race section.
