Eagle Ford 351W 4.170in Crank 6.250in I-Beam Rods -16cc 4.125in Pistons Balanced Assembly

Eagle is a well-known name for building strong engine components, and this rotating assembly is a prime example of their work for Ford 351W engines. If you're putting together a naturally-aspirated racing engine, this balanced assembly gives you a solid foundation to build upon. It includes everything you need to get your short block started, all balanced and ready to go.

At the heart of this assembly is a forged 4340 steel crankshaft with a 4.170-inch stroke. Paired with it are 6.250-inch long I-beam connecting rods, also made from 4340 steel, and they come equipped with 7/16-inch ARP 8740 bolts for a strong connection. The pistons are forged 4032 aluminum from Mahle, featuring an inverted dome design with a -16cc volume and a 4.125-inch bore size. To ensure proper ring seal and performance, it includes plasma-moly file-fit rings. For smooth operation and durability, King XP rod and main bearings are also included.

This assembly is balanced from the factory, saving you a significant step in the engine building process. Please note that this assembly is not CARB approved and cannot be shipped to California. It also carries a California Proposition 65 warning.
