crank bearing question
Doing the top end a 350 for my truck (winter beater) and have questions.
I pulled the bearing caps on my crank (engine is on a stand) and on the main bearing at the back there is one scratch that I can feel with my finger and finger nail but the crank looks fine. It is like a piece of foreign material got in through the oil and scratched the bearing.
My question is how bad do the bearings have to be to change them out??? If they still fit to tolerance can you have a couple of scratches, keeping in mind I am not buidling it to 500 HP just using it as a stock 350 for my truck.
