What is the difference between Race Series bearings and standard bearings?

Race Series bearings from ACL are built with tighter tolerances and often use specialized materials to withstand higher RPMs and increased stress found in performance or racing applications. They are designed for improved durability under demanding conditions compared to standard bearings.

Do these bearings come with a specific oil clearance specification?

ACL Race Series bearings are manufactured to precise specifications. For optimal performance and engine longevity, it is crucial to measure and verify the oil clearance between the bearing and the crankshaft journal during installation, referring to the manufacturer's service manual for the correct range.

What other parts are typically replaced when installing connecting rod bearings?

When replacing connecting rod bearings, it's common practice to also inspect and potentially replace rod bolts and nuts, as well as ensure the crankshaft journals are clean and within spec. Some builders also opt for new piston rings and main bearings during a comprehensive engine rebuild.

Product Details

ACL has been making engine bearings for decades, and this Race Series connecting rod bearing set for your Chevrolet V8 is one of their staples. These bearings are built to handle the demands of performance engines, offering a solid option for anyone rebuilding or upgrading their big block V8. They're designed to provide reliable lubrication and support for the connecting rods, which is crucial for engine longevity and performance, especially when you're pushing the engine harder than stock.

This particular set is for Chevrolet big block engines like the 396, 402, 427, and 454 cubic inch displacements. The Race Series means they're constructed with materials and tolerances suited for higher RPMs and increased stress. When you're installing these, it's important to ensure your crankshaft journals are clean and within factory specifications, as these bearings are precision components. They fit right into the connecting rod and crank throws, making them a direct replacement for your stock bearings, assuming your crank is in good shape.

If you're in the middle of a performance build or a thorough engine overhaul on your classic Chevy, this set is a well-built choice. Make sure to check your specific engine's service manual for proper installation procedures and torque specifications.
