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

This Eagle Street & Strip Rotating Assembly gives you a complete, balanced rotating assembly for your Ford 351W engine. Inside this package, you'll find a 3.850-inch cast crankshaft, a set of 5.956-inch I-beam connecting rods equipped with 3/8-inch ARP 8740 bolts, and hypereutectic KB pistons with an inverted dome design, sized at 4.030 inches. It also includes plasma-moly file-fit rings, King SI rod and main bearings, a damper, and a 157-tooth flexplate, all balanced as a complete unit.

This assembly is specifically put together for pump gas, naturally aspirated street vehicles. The hypereutectic pistons are a solid choice for this type of application, offering good wear resistance and thermal expansion characteristics. The inclusion of ARP bolts in the connecting rods means you're getting strong, reliable fasteners that are well-suited for the stresses of a performance street engine. The file-fit rings allow for precise gapping to match your specific cylinder wall condition and desired clearance, which is a common practice for builders looking to optimize engine performance and sealing.

Having the assembly balanced from the factory saves you a significant step and ensures your rotating assembly is ready to go. This is crucial for engine longevity and smooth operation, as a balanced assembly reduces vibration and stress on bearings and the crankshaft. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. It's designed to be a robust foundation for building a strong street-driven 351W.
