Eagle Ford 351W 4.000in Crank 6.200in H-Beam -28cc Inv Dome 4.030in Pistons Balanced Assembly

If you're building a Ford 351 Windsor for serious racing, especially with power adders like nitrous or a turbo, a strong rotating assembly is the heart of your project. This balanced assembly from Eagle is designed to handle the extreme demands of competition, giving you a solid foundation for a high-horsepower engine.

Eagle starts with a forged 4340 steel crankshaft, measuring 4.000 inches for increased displacement. Paired with this are 6.200-inch H-beam connecting rods, known for their strength and reliability under stress. These rods use 7/16-inch ARP 8740 bolts, a popular choice for their durability. The pistons are forged 4032 aluminum from Mahle, featuring a -28cc inverted dome design that's ideal for achieving specific compression ratios in performance builds. They come with plasma-moly file-fit rings, allowing for precise gap setting during assembly. To ensure smooth operation and longevity, the assembly includes King XP rod and main bearings, which offer improved performance and wear resistance.

This assembly comes balanced from Eagle, saving you a significant step and ensuring proper engine operation right out of the box. Keep in mind that this part is not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure all other components, like the camshaft, cylinder heads, and oiling system, are also suited for high-performance applications.
