Eagle Ford 351W 4.000in Crank 6.200in I-Beam Rods 4.040in Pistons 157 Tooth FP Balanced Assembly

If you're building a high-performance Ford 351 Windsor engine, a balanced rotating assembly is a critical starting point. This assembly from Eagle is designed to handle increased power and RPMs, providing a solid foundation for your project. It includes a 4.000-inch stroke crankshaft, 6.200-inch I-beam connecting rods, and 4.040-inch pistons, all balanced as a complete unit to minimize vibration and ensure smooth operation.

Eagle is known for well-built engine components, and this rotating assembly is no exception. The crankshaft is forged for strength, ready to withstand the demands of a performance engine. The I-beam connecting rods are a popular choice for their balance of strength and weight, suitable for a wide range of builds. The included pistons are sized for a 4.040-inch bore, and the entire assembly is professionally balanced at the factory. This balancing is crucial because it ensures that the crankshaft, rods, pistons, and bearings all work together harmoniously, reducing stress on the engine block and other components, especially at higher engine speeds. The 157-tooth flywheel/flexplate compatible design means it's ready to integrate with common transmission setups.

This assembly is a significant upgrade over stock components and is intended for builders looking to push the performance envelope of their 351W. Keep in mind that this part is not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure you have all the necessary supporting components, such as bearings, rings, and gaskets, which are typically sold separately.
