Eagle Chevy 400 3.750in Crank 5.700in I-Beam Rods -5cc Flat Top 4.155in Pistons Rotating Assembly

This is the Eagle Street & Strip Rotating Assembly, specifically designed for Chevy 400 engines. It's a well-built package intended for vehicles running on pump gas and operating without forced induction, making it a solid choice for street performance builds.

At the core of this assembly is a 3.750-inch cast crankshaft, paired with 5.700-inch I-beam connecting rods. These rods are secured with 3/8-inch ARP 8740 bolts, known for their strength and reliability in performance applications. The pistons are forged 4032 aluminum from ICON, featuring a -5cc flat top design with a 4.155-inch bore, suitable for a 400 cubic inch application. This assembly also includes plasma-moly file-fit piston rings, allowing for precise gap setting during installation to optimize performance and sealing. To complete the package, it comes with King rod and main bearings, which are well-regarded for their durability and performance in demanding engine conditions.

When installing this rotating assembly, remember that the piston rings are file-fit, meaning you'll need to set the end gap yourself. This is a standard procedure for performance builds to ensure proper sealing against the cylinder walls. Due to emissions regulations, this assembly is not CARB approved and cannot be shipped to California. Always consult your vehicle's specific service manual or a qualified mechanic for detailed installation procedures and any additional components you might need for your engine build.
