The main bearing journals on a 350 Chevrolet engine typically have a diameter of 2.45 inches (62.23 mm). The engine features five main bearings, and the standard journal size is designed to provide optimal balance and support for the crankshaft in this small-block V8 engine. Depending on modifications or specific applications, these measurements may vary slightly, but 2.45 inches is the standard size for most factory configurations.
