Product Details

If you're rebuilding the heart of your Chevy 350 for street use, this Eagle Street & Strip rotating assembly is a solid foundation. It's designed to handle pump gas and naturally aspirated setups, making it a great choice for a reliable street machine.

The pistons are hypereutectic KB D-cup style, measuring 4.030 inches with an -18cc dish, which helps achieve a good compression ratio for pump gas.

This rotating assembly is a well-built package for a street-focused Chevy 350 build. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
