MICHIGAN 77 CB663P40 Connecting Rod Bearing Undersize Small Block Chevy - 0.040

The MICHIGAN 77 CB663P40 is a precision-engineered P-Series connecting rod bearing designed for Small Block Chevy V8 engines. This high-performance bearing features a 0.040 inch undersize specification, making it ideal for engines with crankshaft journals that have been machined or require precise dimensional adjustment.

Key Features:

• P-Series design with steel-backed construction for superior strength and durability
• Intermediate layer of copper-lead alloy for enhanced load capacity
• Electroplated lead-tin-copper overlay for optimal wear resistance
• Higher eccentricity and high crush factor to compensate for rod bore distortion in high-RPM applications
• Extra-thin overlay design for improved performance
• 0.040 inch undersize for precision fitment on machined crankshafts

Application:

• Compatible with Chevrolet Small Block V8 engines (1963-2015)
• Fits 262, 265, 267, 292, 294, 302, 305, 307, 327, 350, and 400 cubic inch engines

• Suitable for L6 292 cubic inch inline six engines

The P-Series bearings are specifically engineered for high-revving engines where RPM loads cause connecting rod bores to narrow. This direct replacement bearing provides the reliability and performance needed for both street and performance applications. Sold individually.
