Eagle Ford 351W 3.850in Crank 5.956in I-Beam Rods 4.030in Pistons 157 Tooth FP Balanced Assembly

If you're building a Ford 351 Windsor engine for street and strip use, a well-balanced rotating assembly is crucial for reliable performance. This assembly from Eagle includes a 3.850-inch crankshaft, 5.956-inch I-beam connecting rods, and 4.030-inch pistons, all balanced at the factory. Getting the balance right is key to reducing engine vibration, which helps your engine run smoother and last longer, especially under demanding conditions.

Eagle is known for putting together solid rotating assemblies, and this one is no exception. The I-beam connecting rods are a strong choice for many performance applications, offering a good balance of strength and weight. The included pistons are sized for a 4.030-inch bore, a common size for many 351W builds. Having the assembly factory balanced means you save a significant amount of time and labor during your engine build, and you can be confident in the precision of the balance job. This assembly is designed for a 157-tooth flywheel, which is important to note when selecting your transmission and flexplate.

Keep in mind that this assembly is not CARB approved and cannot be shipped to California. It's always a good idea to consult your engine builder or refer to Eagle's specific installation guidelines to ensure proper assembly and break-in procedures for your new rotating assembly.
