Eagle Ford 351W 4.000in Crank 6.250in H-Beam -26cc Inv Dome 4.040in Pistons Rotating Assembly

This is a complete rotating assembly from Eagle, specifically for Ford 351W engines. It includes a forged 4340 steel crankshaft with a 4.000-inch stroke, 6.250-inch H-beam connecting rods with 7/16-inch ARP 8740 bolts, and Mahle forged 4032 pistons with a -26cc inverted dome. This assembly is designed to handle the demands of serious racing applications, including those using nitrous or forced induction.

The 4340 forged steel crankshaft offers a strong foundation for high-horsepower builds, providing excellent durability under stress. The H-beam connecting rods are well-known for their strength and ability to withstand significant loads, making them a popular choice for performance engines. The Mahle pistons are forged from 4032 aluminum, which offers a good balance of strength and thermal expansion properties, suitable for performance use. They come with plasma-moly file-fit rings, allowing for precise ring gap adjustment during installation to optimize performance and sealing. This assembly also includes King XP rod and main bearings, which are designed for enhanced lubrication and wear resistance in high-performance conditions.

When building a high-performance Ford 351W, a balanced rotating assembly like this is crucial for reliability and power. The components are selected to work together to handle increased cylinder pressures and rotational forces. Please note that this assembly is not CARB approved and cannot be shipped to California. It's recommended to consult with a professional engine builder to ensure proper installation and balancing for your specific application.
