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

If you're building a high-performance Chevy 400 engine for serious competition, a robust rotating assembly is the heart of the operation. This Eagle Heavy Duty Rotating Assembly is designed to handle the extreme demands of exotic fuels, heavy nitrous use, and high boost applications. It's a well-built foundation for an engine that needs to perform under pressure.

At its core, this assembly features a 3.750-inch forged 4340 crankshaft, known for its strength and durability under high stress. Paired with it are 6.000-inch H-beam connecting rods, a popular choice for their strong I-beam cross-section that resists bending and twisting. These rods are secured with 7/16-inch ARP 2000 bolts, a well-regarded fastener known for its reliability in high-stress environments. 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 volume you're aiming for. They come complete with plasma-moly file-fit rings, which allow for precise gap setting to optimize sealing and performance. Finally, the assembly includes King XP rod and main bearings, chosen for their performance characteristics in demanding engine builds.

This rotating assembly is a significant step up from stock components, offering the strength and reliability needed for engines pushed to their limits. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always consult with your engine builder or refer to manufacturer instructions for proper installation and break-in procedures to ensure optimal performance and longevity.
