Eagle Chevy 400 350 Mains 3.750in Crank 5.700in H-Beam -5cc 4.185in Pistons Rotating Assembly

This is the Eagle Competition Rotating Assembly, built for serious performance applications like racing, especially when you're running nitrous or forced induction. It's designed to handle the extra stress these setups put on your engine's core components. This assembly is specifically configured for Chevy 400 blocks using 350 mains, giving you a solid foundation for a powerful build.

At the heart of this assembly is a 3.750-inch forged 4340 crankshaft, known for its strength and durability under high loads. Paired with this are 5.700-inch H-beam connecting rods, a popular choice for their robust design, secured with 7/16-inch ARP 8740 bolts. The pistons are forged 4032 aluminum from Icon, featuring a -5cc flat top design that works with a 4.185-inch bore. This setup includes plasma-moly file-fit rings, which allow for precise gap setting to match your specific engine build and maximize sealing. To complete the package, it comes with King XP rod and main bearings, offering reliable lubrication and wear protection.

When putting this assembly together, remember that the file-fit rings will require careful gapping to ensure optimal performance and longevity. This rotating assembly is a well-built core for a high-horsepower engine build, but it's important to note that it is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed instructions for proper installation and assembly procedures.
