Product Description
Genuine Michigan Engine Bearings 1923 P (NORS)
This listing is for a set of Michigan Engine Bearings, part number 1923 P, offered in New Old Replacement Stock (NORS) condition. This box has a fascinating history, originally starting its life in the factory as a classic flathead inline-6 kit. However, it was professionally converted and re-certified by a commercial engine remanufacturer using a paper overlay label. The parts packaged inside are a 100% complete, full engine set of Crankshaft Main Bearings in Standard Size (STD). This kit contains all 5 positional journal pairs (including the flanged thrust bearing) needed to cradle the crankshaft in a classic Mopar Small Block "LA" V8 engine, specifically for the 273, 318, and 340 CID displacements.

Note on Stock Photos: Due to our inventory of multiple identical units for this specific part number, we utilize representative stock photos for this listing. You will receive a component that strictly meets all listed specifications and fitment requirements. Please be aware that because these are vintage parts, minor cosmetic variations—such as surface finish, color, or production markings—may exist between different manufacturing runs. These slight aesthetic differences are a result of historical production processes and do not impact the part's integrity, performance, or authenticity.
Crucial Mopar 360 V8 Fitment Warning: While this set covers the high-volume 273, 318, and 340 LA small block engines, it will NOT fit the Chrysler 360 V8. The 360 engine block utilizes significantly larger main bearing journal diameters. Engineered strictly for factory-specification standard size crankshafts.
A Note on Fitment Accuracy: We manually research our fitment data using vintage manufacturer catalogs to provide you with the most accurate information possible. However, because we are human and these decades-old resources can occasionally contain errors, we cannot guarantee 100% accuracy. We strongly encourage you to perform your own due diligence and verify this part number for your specific application before purchasing. Please note that this part may also fit other vehicles or years not explicitly listed in our research.
Unbeatable Prices & Expectations
While many of our vintage parts were manufactured decades ago, they remain unused and high-quality. Some original boxes may show signs of shelf-wear, such as dust, tape, or surface distress from years of storage. Rest assured, the components inside have been inspected to ensure they are complete and ready to help you finish your project without breaking the bank.
