Eagle Ford 351W Windsor Rotating Assembly

This Eagle Pro Street Rotating Assembly is built for Ford 351W Windsor engines, specifically for naturally-aspirated racing applications. If you're putting together a performance build for the strip or track, a solid rotating assembly is the heart of your engine, and this kit gives you the core components to get started.

Inside this assembly, you'll find a 4.000-inch forged 4340 steel crankshaft, which is a strong foundation for high-RPM use. Paired with it are 6.200-inch 4340 I-beam connecting rods, known for their durability in performance applications. These rods come with 7/16-inch ARP 8740 bolts, a trusted name for reliable clamping force under stress. The pistons are hypereutectic KB units with an inverted dome design, sized at 4.030 inches and featuring -27.5cc volume, which helps determine your compression ratio. You also get plasma-moly file-fit piston rings, allowing you to set the correct gap for your specific engine build. Finally, the kit includes King XP rod and main bearings, selected for their performance capabilities.

This assembly is intended for racing use and is not CARB approved, meaning it cannot be shipped to California. It's a well-built package for someone serious about building a powerful, naturally-aspirated Ford 351W engine.
