Chevrolet Small Block Large Journal 327 350 400 Rod  Bearings  set of 8

Clevite Connecting Rod Bearing part number: CB663P(8)  Std Size

The steel backing on the Clevite Tri-Metal 77 Connecting Rod Bearings provides strength and durability. The Bi-Metal Babbitt overlay provides the conformability and Load Capacity. The Third layer - Micro-Babbitt overlay provides the critical surface Embedability & Conformability and has far more forgiveness than bi-metal.

This ideal design has properties not found in many original equipment bearings. In most cases Clevite Tri-Metal 77 Bearings are an upgrade over a stock bearing, or three times better.
