Eagle Ford 351W 4.000in Crank 2.750in Journal 6.200in I-Beam Rods 4.030in Pistons Rotating Assembly

Starting with a 4.000-inch forged 4340 crankshaft, this Eagle Pro Street rotating assembly is built for serious performance in Ford 351W engines, particularly for naturally-aspirated racing applications. The crankshaft features 2.750-inch main journals, a common size that balances strength with efficient oiling. This assembly is designed to handle the demands of high-RPM operation where reliability is key.

Complementing the robust crankshaft are 6.200-inch I-beam connecting rods, also forged from 4340 steel for exceptional strength and durability. These rods are secured with 7/16-inch ARP 8740 bolts, known for their superior clamping force and resistance to stretching under load, which is critical for preventing catastrophic engine failure. The assembly includes forged 4032 Icon pistons with a -11cc flat top design, sized at 4.030 inches. These pistons are paired with plasma-moly file-fit rings, allowing for precise gap setting to optimize sealing and performance. King XP rod and main bearings are also included, offering advanced wear resistance and proper oil clearance for the rotating assembly.

This rotating assembly is a well-built foundation for a performance engine build. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always consult manufacturer instructions for proper installation and break-in procedures to ensure the longevity of your new engine components.
