Eagle Ford 351W 4.000in Crank 6.250in I-Beam Rods -6.6cc Flat Top 4.155in Pistons Rotating Assembly

Built around a 4.000-inch stroke forged 4340 steel crankshaft, this Eagle Pro Street rotating assembly is designed for naturally-aspirated racing applications. The crankshaft's robust construction is matched by the 6.250-inch long 4340 I-beam connecting rods, which are secured with 7/16-inch ARP 8740 bolts. These components work together to handle the stresses of performance engines, providing a solid foundation for your build.

The assembly includes forged 4032 Mahle pistons, featuring a -6.6cc flat-top design with a 4.155-inch bore. These pistons are paired with plasma-moly file-fit rings, allowing for precise gap setting to optimize performance and sealing. King XP rod and main bearings are also included, offering excellent durability and reduced friction for critical engine components. This combination is a well-built choice for those looking to assemble a powerful Ford 351W engine for racing purposes.
