This balanced rotating assembly from Eagle is built for serious Ford 351W performance builds, especially those looking to handle forced induction or nitrous. What you get in this kit is a complete package designed to be the heart of your engine. It includes a forged 4340 steel crankshaft with a 4.000-inch stroke and 2.750-inch main journals, paired with 6.250-inch H-beam connecting rods. These rods come with 7/16-inch ARP 8740 bolts, known for their strength and reliability under high stress.

The pistons are forged 4032 aluminum from Mahle, featuring a -26cc inverted dome design and a 4.040-inch bore size.

This entire package is balanced by Eagle, saving you a critical step and ensuring your engine runs smoothly and reliably at higher RPMs.

This assembly is intended for racing applications and is not CARB approved, meaning it cannot be shipped to California. It's a well-built foundation for anyone rebuilding or upgrading their Ford 351W for demanding use.
