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

If you're building a Ford 351W for street use, especially one that will see regular driving on pump gas, a well-balanced rotating assembly is key to a smooth-running and reliable engine. This assembly from Eagle is designed to handle those demands, providing a solid foundation for your build. It's a complete package that takes the guesswork out of matching critical internal components.

This assembly features a 4.000-inch cast crankshaft, paired with 6.200-inch I-beam connecting rods. The rods use 3/8-inch ARP 8740 bolts, which are strong and reliable for street applications. The pistons are Hypereutectic KB flat tops with a -6.5cc dish, designed for a 4.040-inch bore, and come with plasma-moly file-fit rings. King SI rod and main bearings are included to ensure proper clearances and lubrication. To make installation easier and ensure proper balance, this assembly also comes with a damper and a 157-tooth flexplate, and it's factory balanced.

This rotating assembly is a popular choice for street-driven vehicles that are naturally aspirated. It's important to note that this assembly is not CARB approved and cannot be shipped to California. For a complete engine build, you'll want to ensure all other components, like cylinder heads and camshafts, are compatible with this setup to achieve your desired performance and emissions compliance.
