If you're building a high-performance Chevy 400 engine for serious competition, this Eagle rotating assembly is a solid foundation. It's designed to handle the stresses of racing, including nitrous and forced induction setups, giving you the power and reliability you need when it counts.

This assembly starts with a 3.500-inch forged 4340 crankshaft, known for its strength and durability under extreme loads. Paired with it are 6.000-inch H-beam connecting rods, which are a popular choice for their robust design and ability to withstand high RPMs and significant cylinder pressures. These rods come with 7/16-inch ARP 8740 bolts, a name you can trust for secure and reliable connections. The pistons are forged 2618 JE units, featuring a 13cc dome and a 4.125-inch bore size, ready to be fitted with the included plasma-moly file-fit rings. To complete the package, King XP rod and main bearings are included, offering excellent performance and wear resistance for the critical rotating components.

This assembly is specifically configured for Chevy 400 blocks using 350 mains, making it a direct fit for that application. Keep in mind that this part is not CARB approved and cannot be shipped to California. It's a well-built package ready for your next engine build.
