ACL Bearings 8B762P-20 Connecting Rod Bearing Set for Buick V8 400 425 430 455

The ACL Bearings 8B762P-20 is a high-performance connecting rod bearing set designed specifically for Buick big block V8 engines including 400, 425, 430, and 455 cubic inch displacements from 1967-1976. These bearings are engineered to deliver race-proven durability and precision for both street and performance builds.

ACL Race Series bearings feature advanced trimetal construction with a high-strength overlay plate that provides improved fatigue resistance under demanding conditions. The hardened steel backing enhances bearing retention and support, while the reduced overlay thickness on connecting rod bearings optimizes fatigue properties. These bearings are designed with increased eccentricity to compensate for bore distortion at high RPM operation, ensuring reliable oil film formation under extreme loads.

The elimination of flash plating on the bearing backs improves heat transfer and maximizes grip within the bearing housing, while tight wall tolerances help maintain consistent oil clearances throughout your build. ACL bearings use a copper-lead-tin lining material that balances fatigue strength with embeddability, protected by a nickel barrier layer and a low-friction lead-tin-copper overlay for seizure resistance.

This complete connecting rod bearing set fits all Buick big block V8 engines manufactured between 1957 and 1976, making it an ideal choice for engine rebuilds, restorations, and performance applications ranging from street cruising to competitive motorsports.
