Just tore one down myself recently. It's still setting on the engine stand. Last 3 digits of the block are 638. It had a hydraulic roller cam and the block off plate for the mechanical fuel pump opening. It was a greaseball, but, the bores all checked consistant and the crankshaft was good and smooth. Those were the only two pieces I was concerned about.
