Eagle Ford 351W 4.170in Crank 2.750in Mains 6.250in H-Beam -16cc 4.030in Pistons Balanced Assembly

If you're building a high-performance Ford 351W engine for serious racing, a balanced rotating assembly like this one from Eagle is a critical starting point. This assembly includes all the core components you need to get your engine's bottom end built strong, ready to handle the demands of competition, including forced induction or nitrous oxide. It's designed to be a solid foundation for builds pushing the limits.

Eagle starts with a forged 4340 steel crankshaft featuring a 4.170-inch stroke and 2.750-inch main journals, providing a robust core for your engine. Paired with this are 6.250-inch H-beam connecting rods, known for their strength, which come equipped with 7/16-inch ARP 8740 bolts for secure attachment. The pistons are forged Mahle 4032 aluminum with an inverted dome design, measuring 4.030 inches in bore size and featuring a -16cc volume to help achieve your desired compression ratio. This assembly also includes plasma-moly file-fit piston rings, which allow for precise gapping to match your engine's specific needs, and King XP rod and main bearings to ensure smooth rotation and proper oil clearance.

This entire assembly is balanced by Eagle, which is a crucial step for high-RPM engines to reduce vibration and improve overall engine longevity. Having the rotating assembly balanced from the start saves you time and ensures a more precise build. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. It's always recommended to consult with your engine builder to ensure all components meet your specific build goals and local regulations.
