Eagle Ford 351W SVO 4.170in Crank 2.750in Main 6.300in H-Beam -18cc 4.030in Piston Rotating Assembly

If you're building a high-performance Ford 351 Windsor SVO engine, a well-balanced rotating assembly is the heart of your build. This complete package from Eagle includes everything you need to get your short block assembled with strong, reliable components. It's designed to handle the demands of a performance street or strip application, giving you a solid foundation for serious power.

This assembly features a 4.170-inch stroke crankshaft, providing a significant displacement increase over stock for more torque and horsepower. The 2.750-inch main journals are standard for many performance Ford applications, ensuring good compatibility. Eagle's 6.300-inch H-beam connecting rods are well-known for their strength and durability, capable of withstanding high RPMs and increased cylinder pressures. They are paired with 4.030-inch bore pistons, which are dish-shaped with an -18cc volume to help achieve a desired compression ratio, especially when used with aftermarket cylinder heads. The entire assembly is balanced to reduce vibration and ensure smooth operation, which is crucial for engine longevity under stress.

When assembling your engine, proper balancing and clearancing are key. This rotating assembly comes balanced, but it's always a good practice to verify balance, especially if you're using different pistons or a different harmonic balancer. Ensure you have the correct main and rod bearings for your specific block and crank journal sizes. This kit is a great starting point for a custom 351W build, offering a robust combination of components ready for your performance goals.
