Eagle Ford 351W 4.170in Crank 2.750in Mains 6.250in I-Beam Rods 4.125in Pistons Balanced Assembly

If you're building a Ford 351 Windsor for naturally-aspirated racing, this balanced rotating assembly from Eagle is a solid foundation. It includes a forged 4340 steel crankshaft with a 4.170-inch stroke and 2.750-inch main journals, designed to handle the stresses of performance applications. This assembly is balanced at the factory, saving you a significant step in the engine building process.

The kit also features 6.250-inch long 4340 I-beam connecting rods, which are strong and reliable for racing use. These rods come equipped with 7/16-inch ARP 8740 bolts for a secure connection. Forged 4032 aluminum pistons from Mahle are included, featuring an inverted dome design with a -16cc dish and a 4.125-inch bore size. These pistons are paired with plasma-moly file-fit piston rings, allowing for precise gap setting during installation. To complete the rotating assembly, King XP rod and main bearings are supplied, known for their durability and performance in demanding conditions.

This assembly is intended for racing use and is not CARB approved, meaning it cannot be shipped to California. It's important to note that this is a critical component for your engine build, and proper installation by a qualified mechanic is recommended to ensure optimal performance and longevity.
