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

This Eagle rotating assembly starts with a 4.000-inch stroke crankshaft, forged from high-quality steel for strength and durability. It's paired with 6.250-inch long H-beam connecting rods, also forged, which are known for their robust design and ability to handle significant stress. This combination is designed to work within a Ford 351 Windsor engine block, providing a solid foundation for a performance build.

The assembly includes pistons designed for a 4.040-inch bore with a -26cc inverted dome. This specific dome shape and volume are engineered to achieve a particular compression ratio when used with the specified crankshaft and rod length, which is crucial for tuning engine performance. The H-beam rods feature a strong I-beam cross-section, making them a popular choice for builds that see regular track use or demand higher power output than stock. The crankshaft itself is balanced to work with these components, ensuring smooth operation and reducing vibration at higher RPMs.

This rotating assembly is a significant upgrade for anyone rebuilding or modifying a Ford 351W engine who needs a well-built, balanced set of core internal components. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always consult your engine builder or a qualified professional to ensure this assembly meets your specific performance goals and local emissions requirements.
