Eagle Ford 351W 4.000in Crank 6.200in H-Beam -15.8cc Inv Dome 4.030in Pistons Rotating Assembly

Starting with a 4.000 inch stroke forged crankshaft is key to unlocking more displacement and torque for your Ford 351 Windsor. This Eagle rotating assembly is built around that robust crank, paired with 6.200 inch long H-beam connecting rods. The H-beam design is a well-known choice for its strength and reliability under demanding conditions, making it a popular option for performance builds where durability is paramount.

The pistons included are 4.030 inch bore size with a -15.8cc inverted dome dish. This specific dish volume is designed to work with typical 351W cylinder heads to achieve a target compression ratio suitable for many performance applications, often aiming for a street-friendly yet potent combination. Eagle uses forged aluminum for these pistons, offering a strong and lightweight option that can handle higher cylinder pressures and temperatures compared to cast pistons. The entire assembly is balanced, which is a critical step to ensure smooth operation and reduce stress on your engine's main bearings and crankshaft.

This rotating assembly is a significant upgrade for anyone rebuilding or building a performance 351 Windsor engine. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always consult with your engine builder or refer to detailed build specifications to ensure this assembly meets your specific performance goals and engine requirements.
