If you're building a high-performance Ford 351 Windsor engine for serious racing, a balanced rotating assembly is a critical starting point. This assembly from Eagle is designed to handle the demands of competition, whether you're running naturally aspirated, nitrous, or forced induction setups. It includes all the core components you need to get your engine's bottom end rebuilt with strength and precision.

At the heart of this assembly is a 4.000-inch forged 4340 steel crankshaft, chosen for its durability under high stress. Paired with this are 6.250-inch H-beam connecting rods, known for their robust design, secured with 7/16-inch ARP 8740 bolts. The pistons are forged 4032 aluminum from Mahle, featuring a -6.5cc flat top design and a 4.060-inch bore size, ready for plasma-moly file-fit rings. To ensure smooth operation and longevity, the assembly comes complete with King XP rod and main bearings.

This assembly is professionally balanced, which is crucial for reducing engine vibration and ensuring the longevity of your build, especially at higher RPMs. 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 any additional components required for your specific build.
