That's interesting. I bought a 350SDL with ~250,000 miles on the odometer, minimal wear to the interior indicating to me that it is likely correct mileage, and no numbers on the block except for a bar-code sticker on the top of the bell-housing flange on the engine.

This engine had a #22 head, but the cylinders and pistons showed some scuffing, so I assumed it is an original block, ... maybe not?

I've never seen visible wear in cylinders on a 603.96x with these miles, can't imagine that this was a recent new engine.

What I've read is any 603.97x without a stamped identification number by the injection pump is not the original block.

I know for the 603.97x motors is it is not uncommon for it to be burning oil at less then 100,000 miles on the clock. So the cylinder wear you are seeing is not surprising in my view. You were probably looking at the beginning of the motor's demise.
