Oh no, it's not been welded on. The crank and rods came out of a motor that probably had never been torn down. It was a standard bore block and came out of a 65 4 door Impala. I think what happened to it is what Pat was talking about. The areas that are pitted are where the cruddy places were and they were at the upper bearing locations. I figured they would clean up but there is no telling how long this motor had set up. I couldn't use the block as it had a pretty bad crack in the lifter valley. I didn't give anything for it since it was cracked but I got the crank and rods. I'm going to use it anyway. I've had about 6 people tell me it should run just fine. A couple have told me they've seen this before on older cranks. The seal area is pretty slick so I think it will be ok. I may get an offset seal just to be on the safe side.
