Eagle Ford 460 4.300in Crank 6.800in I-Beam Rods -38cc 4.390in Pistons Rotating Assembly

If you're building a Ford 460 engine for naturally-aspirated racing, this Eagle Pro Street rotating assembly is a solid option. It bundles together the core components you need to get your engine's bottom end put together, saving you the hassle of sourcing each piece individually. This assembly is designed to handle the demands of performance applications where forced induction isn't being used.

At the heart of this kit is a 4.300-inch forged 4340 steel crankshaft, chosen for its strength and durability under racing conditions. Paired with it are 6.800-inch 4340 I-beam connecting rods, which are well-built for performance use and come equipped with 7/16-inch ARP 8740 bolts to ensure a secure connection. The pistons are forged 4032 aluminum from Mahle, featuring an inverted dome design with a -38cc volume and a 4.390-inch bore size, which helps achieve a specific compression ratio suitable for naturally-aspirated racing. The assembly also includes plasma-moly file-fit piston rings, allowing for precise gap adjustment during installation, and King XP series rod and main bearings for smooth operation and good wear characteristics.

This rotating assembly is a significant step up from stock components, providing the strength and reliability needed for racing. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. It's crucial to follow the manufacturer's installation instructions carefully, especially when setting piston ring end gaps and bearing clearances, to ensure optimal performance and longevity of your engine build.
