Eagle Chevrolet 400 Balanced Competition Rotating Assembly Kit

If you're building a high-performance Chevrolet 400 engine for serious racing, especially with nitrous or forced induction, a balanced rotating assembly is where you start. This kit from Eagle is designed to handle the demands of competition, giving you a solid foundation for your build.

Inside this kit, you'll find a forged 4340 steel crankshaft with a 4.000-inch stroke, built for strength and durability. Paired with it are 6.000-inch H-beam connecting rods, which are clearanced for stroker applications and feature 7/16-inch ARP 2000 bolts for a strong, reliable connection. The pistons are forged 4032 aluminum from Mahle, designed as flat-tops with a -5cc dish to achieve a specific compression ratio, and they come with plasma-moly file-fit rings. For the bottom end, King XP rod and main bearings are included, known for their robust performance under load.

This assembly comes balanced from the factory, saving you a significant step and cost in your engine build. It's important to note that this kit is not CARB approved and cannot be shipped to California due to emissions regulations. Always consult your engine builder or refer to the manufacturer's instructions for proper installation and assembly procedures.
