Eagle Ford 351W 3.850in Crank 5.956in I-Beam Rods 4.030in Pistons 164 Tooth FP Balanced Assembly

This is a balanced rotating assembly from Eagle, specifically for Ford 351 Windsor engines. It includes a 3.850-inch stroke crankshaft, 5.956-inch I-beam connecting rods, and 4.030-inch bore pistons, all balanced for a 164-tooth flywheel. This assembly is a solid foundation for building a performance street or strip engine, offering a significant displacement increase over stock configurations.

Eagle is known for producing well-built internal engine components, and this assembly is no exception. The I-beam connecting rods are strong and reliable for moderate performance applications. The crankshaft is forged for durability, and the included pistons are designed to work seamlessly with the rods and crank. Having the assembly internally balanced from the factory saves you a significant amount of labor and ensures the critical rotating mass is properly weighted, which is crucial for engine longevity and smooth operation, especially at higher RPMs.

When building a performance engine, the rotating assembly is one of the most critical components. This Eagle assembly takes the guesswork out of matching a crank, rods, and pistons, and the balancing service means it's ready to be installed once you receive it. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. You will also need to ensure you have the correct 164-tooth flywheel for your transmission application.
