The ACL .10mm oversized main bearing set is designed for Chevrolet big-block engines (396, 402, 427, 454) built 1965–2000, providing a 0.10mm oversize to match journals machined by that amount. These bearings re-establish proper clearances after crankshaft work and support reliable rotating assembly operation. Use this size when machining requirements specify a 0.10mm undersize on the journals.
