If you're building a Ford 351W engine for serious competition, like drag racing, extreme nitrous use, or high boost applications, a robust rotating assembly is the heart of your build. This Eagle Heavy Duty Rotating Assembly is designed to handle the immense forces these engines generate, providing a solid foundation for your project.

This assembly starts with a 4.000-inch forged 4340 steel crankshaft featuring 2.750-inch main journals, chosen for its strength and durability under high stress.
