About this part

Product Details

If you're building a high-performance Ford 351W engine for serious racing, a strong rotating assembly is the heart of the operation. This Eagle Competition Rotating Assembly is designed to handle the demands of competition, including nitrous and forced induction applications. It includes all the core components you need to get your engine's bottom end rebuilt with robust parts.

At the center of this assembly is a 4.000-inch forged 4340 steel crankshaft, known for its strength and durability under high stress. Paired with this are 6.250-inch H-beam connecting rods, which are a popular choice for their solid construction and ability to withstand significant loads. These rods come equipped with 7/16-inch ARP 8740 bolts, a well-regarded fastener known for its reliability in performance applications. The pistons are forged 4032 aluminum from Mahle, featuring a flat-top design with a -6.6cc dish and a 4.155-inch bore size, making them suitable for various compression ratio targets. This assembly also includes plasma-moly file-fit rings, allowing for precise gap setting to optimize performance and sealing, along with King XP rod and main bearings for smooth operation.

This rotating assembly is a well-built package for those pushing their 351W engines beyond stock capabilities. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and balancing procedures to ensure optimal performance and longevity.
