What is the main purpose of main bearings in an engine?

Main bearings support the crankshaft within the engine block. They create a low-friction surface for the crankshaft to rotate on, ensuring smooth operation and preventing wear on both the crankshaft and the block.

What does the '2.017in Journal' specification mean?

This refers to the precise diameter of the journal on the crankshaft that the bearing is designed to fit. This specific measurement is crucial for achieving the correct oil clearance, which is the gap between the bearing and the crankshaft, vital for lubrication and performance.

Are these bearings suitable for a stock street engine?

These Clevite Custom Nascar Performance bearings are built for high-stress applications. While they offer excellent durability, they are typically recommended for performance or racing engines where increased loads and heat are expected. For a standard street engine, a different Clevite series might be more appropriate.
