Eagle Chevy 400 3.750in Crank 5.700in H-Beam -16cc 4.185in Pistons Rotating Assembly

This Eagle Competition Rotating Assembly gives you a complete package for building a robust Chevy 400 engine. Inside this kit, you'll find a forged 4340 crankshaft with a 3.750-inch stroke, a set of 5.700-inch H-beam connecting rods secured with 7/16-inch ARP 8740 bolts, and forged 4032 DSS pistons featuring an inverted dome design with a -16cc volume and a 4.185-inch bore. It also includes plasma-moly file-fit piston rings and King XP rod and main bearings to ensure smooth operation.

This assembly is designed for serious performance, making it a solid choice for racing applications, including those using nitrous oxide or forced induction. The forged 4340 crank and H-beam rods are well-built to handle the stresses of high-RPM operation and increased cylinder pressures. The DSS pistons are also forged, offering improved strength over cast alternatives, and their inverted dome design is specifically suited for certain combustion chamber shapes, often found in performance-oriented cylinder heads. The inclusion of ARP bolts means you're getting strong, reliable fasteners for the connecting rods.

When installing this rotating assembly, remember that the piston rings are file-fit, meaning they require careful measurement and adjustment to achieve the correct gap for your specific engine build. This ensures optimal sealing and performance. It's also important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions and torque specifications for proper assembly and break-in procedures.
