Eagle Chevy 400 350 Mains 3.875in Crank 6.000in H-Beam Stroker Rod 4.155in Pistons Rotating Assembly

Eagle is known for building tough engine components, and this rotating assembly is a prime example of that commitment. If you're building a serious performance Chevy 400 engine, especially one that will see extreme competition use like heavy nitrous or high boost, this assembly is designed to handle it. It centers around a 3.875-inch forged 4340 crankshaft, featuring the 350 main journal size for broad compatibility. This crank is paired with 6.000-inch H-beam stroker rods, which are built for extreme duty and come equipped with 7/16-inch ARP 2000 bolts for a solid connection.

The pistons included are forged 2618 JE units, featuring a -5.6cc dome and a 4.155-inch bore size. They come with plasma-moly file-fit rings, giving you the flexibility to set your ring gaps precisely for your application. To ensure smooth operation and durability, the assembly includes King XP rod and main bearings. This combination of high-strength materials and robust components makes it a solid choice for engines pushing the limits, whether you're running exotic fuels or significant boost.

When building a high-performance engine, the rotating assembly is the heart of it all. This Eagle kit provides a well-matched set of critical components, saving you the time and potential headaches of sourcing each piece individually. Remember 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.
