Eagle Ford 351W 4.000in Crank 6.200in H-Beam -5cc Flat Top 4.030in Pistons Rotating Assembly

If you're building a Ford 351W engine for serious competition, like drag racing, extreme boost, or exotic fuels, a robust rotating assembly is the heart of your build. This Eagle Heavy Duty Rotating Assembly is designed to handle the immense forces these applications generate, giving you the confidence to push your engine to its limits.

At its core is a 4.000-inch forged 4340 steel crankshaft, known for its strength and durability under high stress. It's paired with 6.200-inch H-beam connecting rods, which are a popular choice for their excellent strength-to-weight ratio. These rods are secured with 7/16-inch ARP 2000 bolts, a well-regarded fastener known for its reliability in high-performance applications. The assembly includes JE forged 2618 aluminum pistons, featuring a -5cc flat top design and sized at 4.030 inches to achieve a specific displacement. These pistons are matched with plasma-moly file-fit rings, allowing for precise gap setting to optimize sealing and performance. For smooth operation and durability, King XP series rod and main bearings are included, offering enhanced protection for the crankshaft journals.

This rotating assembly is a complete package for those rebuilding or building a high-performance Ford 351W. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always consult your engine builder and manufacturer's instructions for proper installation and tuning to ensure optimal performance and longevity.
