ACL Bearings 8B758A-40 Standard Connecting Rod Bearing Set Pontiac V8

ACL Bearings 8B758A-40 Standard Connecting Rod Bearing Set is engineered specifically for Pontiac V8 engines (350, 400, and 455 cubic inch) from 1955-1979. These advanced bimetal aluminum bearings replace traditional lead-based bearings to meet modern environmental and performance standards while offering enhanced construction and composition that deliver superior strength, durability, and fit for OEM replacement needs.

Key Features:

• Elimination of flash plating on the back of the bearings improves heat transfer and maximizes the grip between the bearings and housing
• Increased eccentricity compensates for bore distortion at high rpm and assists in the formation of hydrodynamic oil films
• Tight consistent wall tolerances help maintain consistent clearances throughout the bearing set
• Standard size connecting rod bearings for direct OEM replacement
• Manufactured to strict quality control standards for reliable performance

These bearings are designed for Pontiac V8 engines that share the same 6.625-inch connecting rod length and 2.249-inch journal size, making them compatible across multiple Pontiac V8 displacements. Whether you're rebuilding a classic muscle car engine or performing routine maintenance, ACL Bearings provides the precision and quality needed for long-lasting engine performance.
