When you're building a serious Ford 351W engine, especially for racing applications like nitrous or forced induction, you need a rotating assembly that can handle the stress. This balanced assembly from Eagle gives you the core components you need to get your build started right. You'll receive a forged 4340 steel crankshaft with a 4.170-inch stroke, paired with 6.250-inch H-beam connecting rods. These rods are secured with 7/16-inch ARP 8740 bolts, known for their strength and reliability under high loads.

The pistons included are forged 4032 aluminum flat-tops from Mahle, featuring a -6.6cc dish to help achieve your desired compression ratio with a 4.125-inch bore. This assembly also comes with plasma-moly file-fit piston rings, which allow for precise gap setting to match your engine's specific needs and operating conditions. To top it off, King XP rod and main bearings are included, offering robust performance for demanding use.

This assembly is balanced from the factory, saving you a significant step and cost in your engine build. It's important to note that this assembly is not CARB approved and cannot be shipped to California.
