Bearing Wear Normal? (pictures)
These are from my bone stock 96 Impala SS engine with 180,000 miles.
Does the wear look typical? Excessive? Better than normal?
Mostly highway miles with Mobil 1 synthetic 5W-30 every 6000-8000 miles.
I have no idea what is considered typical for this many miles.

Now I'm just cleaning and painting the LT1 to put it in an altered dragster.
You think I even need to change the bearings or should I just leave them and reassemble it?

Is there something going on in the middle picture?? Looks like some type of abnormal wear to me. You can see it in the lower one too.
I'm no bearing expert, so the wear may be normal...but can't say I've seen that before.

Could be core shift from the mileage, I had a BBC from 1974 that when assembled, the right side of all main caps didnt sit flush with the block. Motor ran fine except the cam was ground down almost flat on all lobes.
