Eagle Chevy 400 3.750in Crank 6.000in I-Beam Rods -16cc 4.155in Pistons Rotating Assembly

This Eagle Street & Strip Rotating Assembly gives you the core components to rebuild or upgrade your Chevy 400 engine. Inside this kit, you'll find a 3.750-inch cast crankshaft, a set of 6.000-inch I-beam connecting rods equipped with 3/8-inch ARP 8740 bolts, and forged 4032 aluminum pistons. These pistons feature an inverted dome design with a -16cc volume and a 4.155-inch bore size, paired with plasma-moly file-fit piston rings. The assembly also includes King SI rod and main bearings to ensure proper lubrication and wear resistance for your engine's rotating assembly.

Designed for pump gas and naturally aspirated street applications, this assembly is a solid choice for those looking to refresh their Chevy 400. The I-beam connecting rods offer a good balance of strength and weight for street performance, while the forged pistons are built to handle the demands of regular driving. The inclusion of ARP bolts signifies a commitment to reliable fastening under stress, and the file-fit rings allow for precise gap setting to optimize compression and oil control for your specific build.

When installing this rotating assembly, remember that the piston rings are file-fit, meaning you'll need to set the end gap yourself to match your engine's bore and intended use. This level of adjustability is common for performance builds and allows for better sealing. It's important to consult your engine building manual or a trusted resource for the correct ring gap specifications. Please note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations.
