I like .0025 for rods and .0027 for mains with a wet sump engine.

a good rule of thumb is .001 for every inch of shaft diameter + up to .0005 for extra margin of clearance if you feel you need it. On a standard SBC that gives you .0025-.003 on the mains and .002-.0026 on the rods. If you are using thinner oil you will want to stay on the tighter side to keep oil pressure up. You have to be careful not to get too tight or too loose. The load capacity and cooling of the bearing suffers if you go too far one way or the other.
