5.3L that is completely disassembled. The block just came out of the shop last week an got cleaned/checked/new cam bearings installed and honed. All standard sized bearings can be used. I have everything right up to the intake. The engine ran fine when I bought it but I knew it was a high mileage engine and figured I would do a standard rebuild. The machinist recommends new pistons. Buy new pistons/bearings an gaskets and you'll have a new engine.
550 OBO. PM for more details. I can send pictures over text if needed.
