SBC Bearing question

[grtmod3d]

I just pulled a main cap off of a motor and stamped on the bearing is .0006 us is this a special made bearing or is it std. size I dont know if the crank has been turned or not? I dont think my crank has been turned

Thats how GM gets their clearance,by using weird bearings that you can't buy.Unless you mike the crank and torque the cap down and mike it,you don't know what you need.
