Eagle Ford 429/460 Boss9 4.300in Crank 6.800in H-Beam -8cc Flat Top 4.390in Piston Rotating Assembly

When you're building a serious Ford 429/460 engine, especially for racing applications, you need a rotating assembly that can handle the stress. This Eagle Competition Rotating Assembly gives you the core components to get your build started. You'll receive a 4.300-inch stroke 4340 steel crankshaft, 6.800-inch H-beam connecting rods with 7/16-inch ARP 8740 bolts, Mahle -8cc flat top pistons designed for a 4.390-inch bore, plasma-moly file-fit piston rings, and King XP rod and main bearings.

This assembly is built for demanding use, including racing with nitrous or forced induction. The 4340 steel crankshaft is strong and durable, while the H-beam connecting rods are a popular choice for their robust design. The Mahle pistons are forged from 4032 aluminum, known for its good thermal expansion properties, and come with a flat top design and a -8cc dish to help achieve your desired compression ratio. The plasma-moly file-fit rings allow for precise gapping to match your engine's bore and intended use, and the King XP bearings are designed for high-performance applications.

This rotating assembly is a solid foundation for a high-performance Ford big block. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures to ensure the longevity of your new engine components.
