If you're rebuilding a Ford 351W engine for naturally-aspirated racing, this Eagle Pro Street rotating assembly is a solid choice to get your build started right. It bundles together the core components you need to establish your engine's bottom end, saving you time and ensuring compatibility between critical parts.

This assembly features a 4.000-inch forged 4340 steel crankshaft, which is a strong foundation for high-performance applications. Paired with it are 6.250-inch I-beam connecting rods made from 4340 steel, known for their durability under stress. These rods come equipped with 7/16-inch ARP 8740 bolts, a well-regarded choice for their strength and reliability in performance engines. The pistons are forged 4032 aluminum from Mahle, featuring a -6.6cc flat top design and a 4.155-inch bore size. They also include plasma-moly file-fit rings, which allow for precise gap setting to optimize performance and sealing. To complete the package, King XP rod and main bearings are included, offering robust lubrication and wear protection for the crankshaft journals.

This rotating assembly is designed for performance use and is not CARB approved, meaning it cannot be shipped to California. Ensure you consult with your engine builder or refer to manufacturer specifications for proper installation and balancing procedures, as these are critical steps for any performance engine build.
