Eagle Ford 429/460 4.140in Crank 6.700in H-Beam -28cc 4.440in Pistons Rotating Assembly

Eagle is well-known for building robust engine components, and this rotating assembly for the Ford 429/460 is a prime example of their commitment to performance. If you're building a serious engine for racing, especially one that will see nitrous or forced induction, this assembly is designed to handle the extra stress.

At its heart is a 4.140-inch forged 4340 steel crankshaft, chosen for its strength and durability under high loads. Paired with this are 6.700-inch H-beam connecting rods secured by 7/16-inch ARP 8740 bolts, a combination that offers excellent rigidity. The pistons are forged 4032 aluminum from Mahle, featuring an inverted dome design with a -28cc volume and a 4.440-inch bore size, which helps achieve a specific compression ratio suitable for boosted or nitrous applications. This assembly also includes plasma-moly file-fit piston rings, which allow for precise gap setting to optimize performance and sealing, and King XP rod and main bearings to ensure smooth operation and longevity.

This is a complete rotating assembly, meaning it includes the crankshaft, connecting rods, pistons, rings, and bearings. It's a substantial upgrade for anyone looking to build a high-performance Ford 429/460 engine. Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures.
