When you're building a Ford 351W for serious naturally-aspirated racing, you need a rotating assembly that can handle the stress. This balanced assembly from Eagle gives you the core components to get your engine project rolling. You get a forged 4340 steel crankshaft with a 4.000-inch stroke and 2.750-inch main journals, ready to be the heart of your build. It's paired with 6.250-inch long 4340 I-beam connecting rods, which come with 7/16-inch ARP 8740 bolts for a strong connection.

The pistons included are forged 4032 aluminum with a -26cc inverted dome design, suitable for a 4.125-inch bore. These come with plasma-moly file-fit piston rings, giving you the flexibility to set your ring gaps precisely for your application. To round out the assembly, King XP rod and main bearings are included, offering solid lubrication and wear resistance. This entire package is balanced by Eagle, saving you a critical step and ensuring your engine runs smoothly.

Keep in mind that this assembly is not CARB approved and cannot be shipped to California. It's designed for performance builds where maximum power from a naturally-aspirated setup is the goal.
