Eagle Ford 351W 4.170in Crank 2.750in Mains 6.250in H-Beam 4.040in Pistons Balanced Assembly

If you're rebuilding a Ford 351W for serious racing, especially with power adders like nitrous or a turbo, a balanced rotating assembly is a critical starting point. This Eagle Competition Rotating Assembly is designed to handle the stresses of competition, providing a solid foundation for your high-performance engine build.

This assembly starts with a forged 4340 steel crankshaft featuring a 4.170-inch stroke and 2.750-inch main journals. The connecting rods are 6.250-inch long H-beams, which are known for their strength and are secured with 7/16-inch ARP 8740 bolts, a popular choice for their reliability under high loads. The pistons are forged 4032 aluminum from Mahle, a -6.6cc flat-top design with a 4.040-inch bore, and come with plasma-moly file-fit rings, allowing for precise gap setting. To ensure smooth operation and durability, the assembly includes King XP rod and main bearings.

This rotating assembly comes balanced from Eagle, saving you a significant step and ensuring proper engine balance right out of the box. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
