ACL Chevrolet V8 305-350-400 Race Series Engine Connecting Rod Bearing Set

If you're rebuilding the bottom end of your Chevrolet V8, especially one of the popular 305, 350, or 400 small blocks, you're probably looking for reliable connecting rod bearings. These ACL Race Series bearings are built to handle the demands of a performance or rebuilt engine. They're designed to provide a solid foundation for your rotating assembly, ensuring proper oil clearance and smooth operation.

ACL has been making engine bearings for a long time, and this Race Series set uses a tri-metal construction. This means it's got layers of different materials to offer good strength and wear resistance, while also being able to hold oil well. The 'HD' in the part number often signifies a heavy-duty application, which is exactly what you want when you're putting an engine back together for serious use. They fit a wide range of Chevrolet V8s, from classic small blocks to many of the LS-based engines, so double-check the fitment list to make sure they're right for your specific application.

When you're installing these, make sure your crankshaft journals are clean and within spec for size and finish. Proper oil clearance is critical for bearing life, so always measure and verify before buttoning everything up. This set is a popular choice for builders looking for a well-built bearing that offers good performance without breaking the bank.
