Eagle is well-known for making strong internal engine components, and this Pro Street Rotating Assembly is a prime example for your Ford 351W build. If you're putting together a naturally-aspirated racing engine, this assembly is designed to handle the demands of the track. It's a comprehensive package that gives you the core rotating parts needed to rebuild or upgrade your engine's bottom end.

This assembly starts with a 4.170-inch forged 4340 steel crankshaft, which is a solid foundation for high-performance applications. Paired with it are 6.250-inch I-beam connecting rods made from 4340 steel, known for their strength and reliability under stress. These rods come equipped with 7/16-inch ARP 8740 bolts, a trusted name in high-strength fasteners, ensuring a secure connection. The pistons are forged 4032 aluminum from Mahle, featuring an inverted dome design with a -16cc dish and a 4.030-inch bore size, which is +.030 inches over the standard bore. They come with plasma-moly file-fit rings, allowing for precise gap setting to match your engine's specific needs. To complete the rotating assembly, King XP rod and main bearings are included, offering excellent wear resistance and performance.

This is an unbalanced rotating assembly, meaning it will require balancing by a professional machine shop to match your specific flywheel and harmonic balancer for optimal engine operation and longevity. Please note that this assembly is not CARB approved and cannot be shipped to California. It's important to consult with your machine shop regarding the balancing process and any other components you may need to complete your engine build.
