I'm in the middle of putting a 3.8L together and am right in the middle of plastigauging the mains. The first one went in great and mesured a bit loose, but still in spec.
Onto the second main. The upper (block side) snapped into place and centered just fine. When I looked at the lower (cap side) it doesn't look like the notch is centered like the other 19 bearings (used and new). For the sake of a better visual I loaded the cap onto the crank and took a picture. You can see the bearing sticking out. I don't think I have feelers thick enough to read the distance between the bearing and the counter weight, but I'd say it sticks out roughly 1/32 of an inch from the cap.
The crank was polished and the bearings are new. Cutting the bearing isn't an option, I might as well buy a new bearing kit if thats your answer. I just don't see this being right.
