About this part

Product Details

When you're building or rebuilding a Chevrolet big block V8, especially for performance use, the connecting rod bearings are a critical component. This Race Series set from ACL is built with a special overlay material that's designed to handle the higher loads and temperatures you'll see in these engines, whether it's a 396, 402, 427, or 454ci. They're a solid option when you need more than what a standard bearing can offer.

ACL uses a tri-metal construction in their Race Series bearings. This means you get a strong steel backing for rigidity, a copper-lead alloy layer for good embeddability and load carrying, and a final overlay of babbit for excellent conformability and reduced friction. This combination helps these bearings stand up to the demands of performance applications, offering improved durability over stock bearings when you're pushing your engine hard.

This set is designed to fit a wide range of Chevrolet V8 engines from the mid-60s through the mid-70s, covering displacements from 396ci up to 454ci, and even the 496ci Gen IV Vortec. Make sure to check the fitment details to confirm it matches your specific application.
