Eagle Chevy 400 350 Mains 3.500in Crank 6.000in H-Beam 13cc Dome 4.155in Pistons Rotating Assembly

Eagle is well-known for building robust engine components, and this Competition Rotating Assembly is a prime example of their commitment to performance. If you're building a high-horsepower Chevy 400 engine, especially for racing applications like nitrous or forced induction, this assembly is designed to handle the stress. It brings together all the critical rotating parts you need to get your engine internals sorted, saving you time and ensuring compatibility between components.

At the heart of this assembly is a 3.500-inch forged 4340 crankshaft, chosen 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 solid construction and ability to withstand high RPMs and significant cylinder pressures. These rods come equipped with 7/16-inch ARP 8740 bolts, a name trusted for their reliability in high-stress engine builds. The pistons are forged 2618 JE units, featuring a 13cc dome and a 4.155-inch bore size, designed to work with the compression ratio and displacement of a Chevy 400. They come with plasma-moly file-fit rings, allowing for precise gap setting to optimize performance and sealing. To ensure smooth operation and proper lubrication, the assembly includes King XP rod and main bearings, known for their performance in demanding conditions.

This rotating assembly is a comprehensive package for serious engine builders. 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.
