ACL 1967-1998 Chevy V8 267/305/327/350 .50mm Trimetal Oversized Main Bearing Set

Doing an engine rebuild on your classic Chevy Camaro, C10 Pickup, or Impala? If you're working on a small-block V8 like the 267, 305, 327, or 350, this ACL main bearing set is a solid choice. These bearings are designed to replace the original main bearings, and they're 0.50mm undersize, which is important if your crankshaft journals have been machined down during the rebuild process. ACL uses a trimetal construction, which is well-known for its strength and ability to handle the pressures and heat inside your engine.

When you're rebuilding an engine, getting the bearing clearances just right is critical for oil flow and engine longevity. These ACL bearings are made to precise specifications to help you achieve those correct clearances. The trimetal design offers a good balance of hardness and conformability, allowing the bearing to properly seat itself against the crankshaft while still providing a durable surface. This set is specifically for the main bearings, which support the crankshaft in the engine block.

Make sure to check your crankshaft journal measurements before ordering. If your journals have been machined down by 0.50mm (or 0.020 inches), this set will be the correct fit. Always refer to your vehicle's specific service manual for detailed installation instructions and proper torque specifications.
