Eagle Chevy 400 350 Mains 3.750in Crank 5.700in I-Beam Rods -16cc 4.165in Pistons Rotating Assembly

This Eagle Pro Street rotating assembly gives you the core components to rebuild or upgrade your Chevy 400 engine. You get a forged 4340 steel crankshaft with 3.750-inch stroke, designed to use 350 main journal sizes. It also includes 5.700-inch long I-beam connecting rods made from 4340 steel, which come equipped with 7/16-inch ARP 8740 bolts for a strong connection. The assembly is rounded out with forged 4032 aluminum pistons featuring a -16cc inverted dome design and a 4.165-inch bore size, along with plasma-moly file-fit piston rings and King XP rod and main bearings.

This combination is built for naturally-aspirated racing applications, meaning it's intended for engines that don't use a turbocharger or supercharger. The use of forged 4340 steel for both the crankshaft and connecting rods signifies a well-built component capable of handling higher stresses than cast alternatives. The ARP bolts are a notable inclusion, known for their strength and reliability in performance engine builds. The pistons are designed with a specific dome volume (-16cc inverted dome) to achieve a desired compression ratio when paired with appropriate cylinder heads, and the plasma-moly rings are designed for good sealing and durability.

When planning your build, remember that this assembly is not CARB approved and cannot be shipped to California. It's important to consult with your engine builder or refer to detailed build specifications to ensure this rotating assembly meets your specific performance goals and engine requirements.
