Eagle Ford 351W Balanced Rotating Assembly Kit 164 Tooth Flex Plate

If you're rebuilding the heart of your Ford 351W for street use, a balanced rotating assembly is a critical step for smooth operation and reliability. This kit from Eagle takes the guesswork out of matching components, providing a well-matched set of parts designed to work together for pump gas, naturally aspirated applications.

This assembly starts with a 4.000-inch cast crankshaft, paired with 6.200-inch I-beam connecting rods secured by 3/8-inch ARP 8740 bolts. For the pistons, you get hypereutectic KB inverted dome pistons (4.060-inch bore) with plasma-moly file-fit rings, which are known for their good sealing and durability on the street. King SI rod and main bearings are included to ensure proper lubrication and wear resistance for the rotating assembly. To complete the package, this kit also includes a damper and a 164-tooth flexplate, making it a comprehensive solution for your engine build.

This is a balanced assembly, meaning the crankshaft, pistons, rings, and connecting rods have been balanced together at the factory. This balance is crucial for reducing engine vibration and ensuring longevity, especially in street applications. Please note that this assembly is not CARB approved and cannot be shipped to California.
