MICHIGAN 77 CB745P40 Connecting Rod Bearing Undersize Small Block Chevy - 0.040

The MICHIGAN 77 CB745P40 is a high-performance connecting rod bearing designed for Small Block Chevy engines including 265, 283, 302, and 327 cubic inch displacements. This bearing features a 0.040 inch undersize specification, making it ideal for crankshafts that have been machined or require oversized bearings for proper clearances.

Key Features:

• P-Series Tri-Metal construction with copper-lead alloy layer for superior strength and durability
• High crush qualities ensure maximum bearing retention in the connecting rod
• High eccentricity design accounts for bore distortion under load
• Reduced overlay thickness helps prevent bearing fatigue
• Precision electroplated white metal babbitt surface layer provides excellent conformability and embedability
• Color-coded for quick identification and installation accuracy

This P-Series bearing is ideal for rebuilding engines where more demanding use is anticipated, including heavy-duty applications, motorsports, and street performance builds. As the most versatile replacement option, it is suitable for most OE applications and serves as an excellent upgrade from bi-metal engine bearings due to its increased load capacity. Sold individually as a connecting rod bearing pair.
