Bearing wear

[Byard-HWJ]

I have attached a couple of pictures of one of the main caps and rod cap bearings form a 160k mile 1993 454 I’m working on. Does this wear seem excessive. The crank appears to smooth without any grooves or distortion. These are the only 2 I have removed so far.

To me, it doesn’t look excessive for 160k miles. There’s a lot of wear but no brass(?) showing so it’s not too deep. I wonder about the odd pattern towards the side of the rod bearing though.

I don't see any copper/brass color,
Picture on right has a funny spot on the right side?

160k no wear is not excessive. How far are you going with this engine out of truck on an engine stand,or working pan off,underneath the truck? What are you trying to accomplish?
