What is the main difference between these Race Series bearings and standard bearings?

These ACL Race Series bearings use a special overlay material that's tougher and more resistant to wear under high loads and temperatures. They are designed for performance builds where standard bearings might not hold up as well.

Does this set include bearings for all connecting rods?

Yes, this kit includes a full set of connecting rod bearings for your V8 engine. You'll have enough bearings to replace all of them during your engine build or rebuild.

What does the 'H' in the part number 1B663H-11 signify?

The 'H' in the part number indicates that these are standard size bearings. This means they are intended for use on a crankshaft with factory-specified journal dimensions, or one that has been machined back to standard size.

About this part

Product Details

When you're building or rebuilding a Chevrolet V8 engine, especially one in the 305, 350, or 400 cubic inch range, getting the connecting rod bearings right is crucial for performance and longevity. These ACL Race Series bearings are built for those demanding applications where reliability under stress is key. They're made to handle the higher loads and temperatures that come with performance builds.

ACL has been making engine bearings for a long time, and this Race Series set uses a special overlay material that's designed to be tough and resist wear, even when you're pushing your engine hard. They're a popular choice for anyone looking to get the most out of their V8, whether it's for a street car or something more track-focused. The 'H' in the part number indicates a standard size, so make sure you're replacing bearings of the same size or have the crankshaft professionally measured and machined to suit.

This set includes bearings for all the connecting rods in your V8. It's a good idea to check your crankshaft journals for any damage or out-of-round conditions before installing new bearings. If you're unsure about the process, it's always best to consult your vehicle's service manual or a trusted mechanic.
