This is a complete rotating assembly from Eagle, designed for Chevy 400 and 350 main applications. It's a well-built package that includes everything you need to get your engine's core rotating components sorted, whether you're building a street machine or a serious race engine. The heart of this assembly is a 3.750-inch forged 4340 crankshaft, known for its strength and durability under high stress.

Paired with the crank are 5.700-inch H-beam connecting rods. These rods are forged from 4340 steel and come equipped with 7/16-inch ARP 8740 bolts, a popular choice for their reliability in demanding applications. The pistons are forged 4032 DSS units, featuring an inverted dome design with a -16cc volume and a 4.125-inch bore size. They come with plasma-moly file-fit rings, which allow for precise gap setting to match your specific engine build and intended use. To complete the package, King XP rod and main bearings are included, offering solid performance and protection for the crankshaft and connecting rod journals.

This assembly is engineered for competition use, including applications with nitrous or forced induction. Please note that this part is not CARB approved and cannot be shipped to California. It's always a good idea to consult with your engine builder to ensure all components meet your specific build requirements and local emissions regulations.
