What does the 0.0010 inch undersize mean for these bearings?

The 0.0010 inch undersize indicates that these bearings are intended for use with a crankshaft that has been machined down by 0.0010 inches from its original factory size. This ensures a precise fit and proper oil clearance on a reground or undersized crankshaft.

Are these bearings suitable for a stock 351 Cleveland engine?

While these are Race Series bearings, they can be used in a stock engine if you are looking for improved durability. However, they are specifically designed to handle the higher loads and stresses found in performance or racing applications.

What is the typical lifespan of these performance bearings?

The lifespan of engine bearings depends heavily on proper installation, oil quality and maintenance, and the specific operating conditions of the engine. For performance builds, regular oil changes and inspections are key to maximizing bearing life.

Product Details

When you're building a performance Ford 351 Cleveland V8, the right bearings are critical. These ACL Race Series main bearings are built with a high-performance overlay and a hardened steel backer, designed to handle the increased loads and stresses of a performance engine. They're a solid choice for anyone looking to get the most out of their Cleveland build, whether it's for racing or just a serious street performance application.

ACL uses a tri-metal overlay with a high-strength steel backing for these Race Series bearings. This construction helps them maintain their shape and oil clearance under extreme conditions, which is crucial for preventing engine damage. The 0.0010 inch undersize means they're intended for crankshafts that have been machined to a slightly smaller diameter, ensuring a precise fit and proper oil film.

This set includes the main bearings needed for your 351 Cleveland. If you're rebuilding your engine, make sure you have the correct specifications for your crankshaft machining before ordering. It's always a good idea to consult your engine's service manual or a trusted builder for specific installation details and torque specifications.
