What is the purpose of main bearings in an engine?

Main bearings support the crankshaft within the engine block. They create a low-friction surface that allows the crankshaft to rotate smoothly while handling the significant forces from the pistons and connecting rods.

Do these bearings come with assembly lube?

This ACL main bearing set does not include assembly lube. It is recommended to use a high-quality engine assembly lubricant during installation to protect the bearings and crankshaft journals.

What engine sizes are covered by this bearing set?

This set is designed for Chevrolet V8 engines with displacements ranging from 267 cubic inches up to 350 cubic inches.

About this part

Product Details

Already running a rebuilt V8 engine? This main bearing set is the next piece of the puzzle for your 1967-1973 Chevrolet Camaro. These bearings sit between the crankshaft and the engine block, supporting the rotating assembly and handling the immense forces generated during combustion. When you're rebuilding an engine, especially one with a few miles on it, replacing the main bearings is a critical step to ensure smooth operation and longevity.

ACL has been making engine bearings for a long time, and this set is built to handle the demands of Chevrolet V8s from 267 to 350 cubic inches. They're made with a multi-layer material that's designed to withstand the pressures and temperatures inside your engine. Proper installation is key here; make sure your crankshaft journals are clean and within spec, and always use a good assembly lube. This set is designed as a direct replacement, meaning it fits right into the factory locations.

This set is specifically for the 1967-1973 Camaro, but it also fits a range of C10 Pickups and Impalas from various years. If you're in the middle of a V8 rebuild, getting the right bearings in place is fundamental to a successful outcome.
