King Engine Bearings Chevrolet 265/283/302/327 V8 (Size STDX) Main Bearing Set

If you're rebuilding the bottom end of a classic Chevrolet V8 like a 265, 283, 302, or 327, getting the right main bearings is crucial for engine longevity and performance. These King Engine Bearings MB554XPSTDX are part of their pmax black racing line, meaning they're built with a tri-metal material designed to handle the higher stresses of performance applications.

The STDX size indicates these bearings are specifically sized for certain engine builds, often used when the crankshaft has been machined. King uses a special overlay material that's tougher and more resistant to wear, which is important when you're pushing an engine harder than stock. This makes them a solid option for anyone building a performance or race engine where reliability under load is key.

This set fits a wide range of Chevrolet V8 engines found in vehicles from the mid-50s through the late 60s, including popular models like the Chevrolet Impala, Chevelle, and Corvette. Make sure to check your specific engine's requirements and crankshaft specifications to ensure this STDX size is the correct fit for your build.
