If you're building a serious performance Ford 429 or 460 engine for racing, a strong rotating assembly is the heart of the operation. This Eagle Competition Rotating Assembly kit is designed to handle the demands of competition, whether you're running naturally aspirated, nitrous, or forced induction setups. It gives you the core components needed to build a robust short block that can take a beating and keep performing.

Inside this kit, you'll find a forged 4340 steel crankshaft with a 4.300-inch stroke, providing the foundation for increased displacement and torque. Paired with this are 6.800-inch H-beam connecting rods, known for their strength and reliability under stress. These rods come equipped with 7/16-inch ARP 8740 bolts, a well-regarded choice for their clamping power. The pistons are forged 4032 aluminum from Mahle, featuring a -3cc flat-top design for a 4.390-inch bore, and they come with plasma-moly file-fit rings, allowing for precise gap setting to match your specific build. To complete the assembly, King XP rod and main bearings are included, offering excellent wear resistance and smooth operation.

This kit is a comprehensive package for anyone serious about building a high-performance Ford big block. Remember that this assembly is not CARB approved and cannot be shipped to California. It's recommended to consult with your engine builder or refer to manufacturer instructions for specific assembly details and torque specifications to ensure a proper build.
