Eagle Ford 351W 3.750in Crank 6.250in I-Beam Rods 4.030in Pistons 157 Tooth FP Balanced Assembly

If you're building a Ford 351 Windsor engine for street performance or strip duty, a balanced rotating assembly is a critical starting point. This assembly from Eagle includes a 3.750-inch stroke crankshaft, 6.250-inch I-beam connecting rods, and 4.030-inch pistons, all balanced at the factory. Getting the balance right from the start saves you time and ensures your engine runs smoothly and reliably at higher RPMs.

Eagle has put together a well-built package here, featuring a forged crankshaft and strong I-beam connecting rods designed to handle the stresses of performance driving. The included pistons are sized for a 4.030-inch bore, a common size for many 351W builds. This assembly is factory balanced for a 157-tooth flywheel, which is standard for many automatic transmissions and some manual setups. This means you can install it with confidence, knowing the critical rotating components are already matched for optimal performance and longevity.

This rotating assembly is a solid foundation for your next engine project. 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 like bearings, rings, gaskets, and a suitable camshaft to match the performance potential of this assembly.
