What is the significance of the .001 inch oil clearance?

The .001 inch oil clearance is a precise measurement that helps ensure optimal oil flow and lubrication between the crankshaft and the main bearings. This tight clearance is important for reducing friction and wear, especially in performance applications where engine loads can be higher.

Are these bearings suitable for a stock engine rebuild?

Yes, while marketed as high performance, these standard size bearings with precise oil clearance are well-suited for stock engine rebuilds. They offer improved lubrication control and durability compared to some OEM bearings, contributing to a longer-lasting engine.

Does this set include all the necessary main bearings for an engine rebuild?

This set includes the main bearings required for the crankshaft. It is important to verify if any other bearing sets, such as rod bearings or thrust bearings, are needed for your specific engine rebuild project, as they are typically sold separately.
