What does the '0.010' mean in the part number?

The '0.010' indicates that these bearings are 0.010 inches undersize. This means they are designed to fit crankshaft journals that have been machined down by 0.010 inches, often done during an engine rebuild to ensure a precise fit on worn or reconditioned journals.

Are these bearings suitable for a stock engine rebuild?

While these are Race Series bearings, they can be used in a stock rebuild if the crankshaft journals have been machined to the 0.010" undersize specification. For a completely stock, unmachined crankshaft, you would typically need standard size bearings.

What is the primary benefit of using Race Series bearings?

Race Series bearings are built with materials and designs that can withstand higher loads and temperatures commonly found in performance or racing engines. This offers improved durability and reliability compared to standard bearings when the engine is pushed harder.

About this part

Product Details

When you're building a performance V8, the details matter. These ACL Race Series conrod bearings are designed for Chevrolet engines displacing 265 to 327 cubic inches. They're built to handle the extra stress and heat that comes with a performance build, ensuring your engine stays reliable when you push it hard.

This set is specifically sized at 0.010 inches undersize. This is common when rebuilding an engine that may have had previous machine work or slight wear on the crankshaft journals. Using an undersize bearing allows for a fresh, precise fit, which is critical for proper oil clearance and bearing life in a high-performance application. ACL uses well-built materials and a design focused on durability to keep your engine running strong.

If you're working on a classic Chevy V8 for racing or serious street performance, these bearings are a solid choice. Make sure to check your crankshaft journal dimensions to confirm that the 0.010" undersize is appropriate for your specific build.
