Eagle Chevy 400 350 Mains 3.875in Crank 6.000in H-Beam Stroker 4.165in Pistons Balanced Assembly

Starting with a 3.875-inch forged 4340 steel crankshaft, this balanced rotating assembly is built for serious performance applications. It's designed to fit Chevy 400 blocks using 350 main journal sizes, which can simplify sourcing and installation for many builders. This assembly is intended for engines that will see extreme competition use, including those running exotic fuels, heavy nitrous oxide injection, or high boost levels.

The heart of this stroker assembly includes 6.000-inch H-beam connecting rods, known for their strength and reliability under high stress. These rods are secured with 7/16-inch ARP 2000 bolts, a popular choice for their durability and clamping force. Paired with the crank and rods are forged 2618 aluminum pistons featuring a -10.8cc dome and a 4.165-inch bore size, designed to work with the stroker crank for increased displacement. The pistons come with plasma-moly file-fit rings, allowing for precise gap setting to match your engine's specific needs and operating conditions. King XP rod and main bearings are included, offering robust performance and wear resistance for demanding builds.

This assembly comes balanced from Eagle, saving you a significant step in the engine building process. It's important to note that this part is not CARB approved and cannot be shipped to California. Always consult your engine builder and manufacturer's specifications for proper installation and tuning.
