ACL **Coated** Chevrolet V8 267-305-327-350 Race Series Engine Crankshaft Main Bearing Set

Rebuilding the top end of your classic Chevrolet V8? When you're getting into the bottom end, especially for a performance build or a tight rebuild, the crankshaft main bearings are critical. These ACL Race Series main bearings are built to handle the demands of a performance engine, offering a solid foundation for your rotating assembly.

ACL has been making bearings for a long time, and this Race Series set is designed with performance in mind. They feature a special coating that helps reduce friction and improve oil retention, which is super important for keeping things cool and reducing wear under load. This particular set is 0.010 inch undersize, meaning it's meant for a crankshaft that has been machined down by 0.010 inches to ensure a perfect, snug fit. Getting the right bearing clearance is key for engine longevity and performance, and these bearings help you achieve that.

When you're putting in new main bearings, it's a good idea to check your crankshaft journals for straightness and ensure they've been properly machined if you're using an undersize set like this. Make sure all your oil passages are clean and clear before installation.
