ACL Chevrolet V8 396/402/427/454 Race Series 10 Oversize Main Bearing Set

ACL has been making engine bearings for decades, and this Race Series main bearing set for your Chevrolet V8 is one of their staples. These bearings are designed for performance applications, helping to ensure your engine's crankshaft stays properly supported under demanding conditions. This set is specifically sized at 0.010 inches oversize, which is crucial if your crankshaft journals have been machined to this size during an engine rebuild.

The Race Series bearings feature a specialized overlay material that offers improved strength and durability compared to standard bearings. This construction helps them withstand higher loads and temperatures often found in performance or racing engines. They are built with tight tolerances to minimize oil clearance, which is important for maintaining oil pressure and preventing excessive movement of the crankshaft. When you're rebuilding a performance V8, getting the bearing clearances right is key to a healthy, long-lasting engine.

This set is intended for Chevrolet big-block V8 engines, including the 396, 402, 427, and 454 cubic inch displacements. Make sure to verify your engine size and that your crankshaft has been machined to a 0.010 inch oversize before ordering. Proper installation according to manufacturer guidelines is essential for optimal performance and longevity.
