Eagle Chevy 400 350 Mains 3.750in Crank 6.000in H-Beam -5.6cc Dome 4.165in Pistons Rotating Assembly

Eagle is well-known for making strong engine components, and this rotating assembly is a prime example of their commitment to performance. This is a complete package designed for serious engine builds, specifically for Chevy 400 blocks using 350 main journal sizes. If you're building a high-performance engine that needs to handle extreme conditions like exotic fuels, heavy nitrous use, or high boost, this assembly is engineered to take that abuse.

At the heart of this assembly is a 3.750-inch forged 4340 crankshaft, chosen for its strength and durability under high stress. It's paired with 6.000-inch H-beam connecting rods, which are a popular choice for their robust design and ability to handle significant power. These rods come equipped with 7/16-inch ARP 2000 bolts, known for their reliability in high-performance applications. The pistons are forged 2618 JE units, featuring a -5.6cc dome and a 4.165-inch bore size, designed to work with the specific compression ratio and cylinder head combination you're aiming for. They also include plasma-moly file-fit rings, which allow for precise gap setting to optimize performance and sealing. To round out the package, King XP rod and main bearings are included, offering excellent wear resistance and smooth operation for critical rotating components.

This assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. It's a well-built foundation for a powerful engine, providing the strength and reliability needed for demanding applications.
