Eagle Chevy 400 3.750in Crank 6.000in H-Beam -16cc 4.185in Pistons Rotating Assembly

This is the Eagle Chevy 400 Competition Rotating Assembly, designed for serious performance builds. If you're putting together a Chevy 400 small block for racing, especially with power adders like nitrous or forced induction, this assembly is built to handle the stress. It includes a forged crankshaft, connecting rods, pistons, rings, and bearings, giving you a solid foundation for your engine's bottom end.

At the core of this assembly is a 3.750-inch forged 4340 steel crankshaft, known for its strength and durability under high loads. Paired with it are 6.000-inch H-beam connecting rods, also forged from 4340 steel, and secured with 7/16-inch ARP 8740 bolts. These rods are a popular choice for performance applications because they offer a good balance of strength and weight. The pistons are forged 4032 aluminum with an inverted dome design, featuring a -16cc volume and a 4.185-inch bore size, which helps achieve a specific compression ratio depending on your cylinder heads. They come with plasma-moly file-fit rings, allowing for precise gap setting to match your engine's bore and intended use. To complete the rotating assembly, King XP rod and main bearings are included, offering robust lubrication and wear resistance for high-performance engines.

This is a competition-level rotating assembly, meaning it's built for demanding use. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. It's a comprehensive package for anyone looking to build a powerful Chevy 400 engine for racing applications.
