Product Details
Eagle is well-known for building strong engine components, and this balanced rotating assembly is a prime example of their work for Chevy 400 engines. If you're looking to build a serious performance engine, especially one intended for racing, nitrous, or forced induction, this assembly is designed to handle the extra stress. It includes everything you need to get your bottom end rebuilt with robust parts.
At the heart of this assembly is a 4.000-inch forged 4340 crankshaft, chosen for its strength and durability under high loads. Paired with it are 6.000-inch H-beam connecting rods. These rods are built with extreme stroker clearance, meaning they're designed to work with the longer stroke of the crankshaft without interference. They come equipped with 7/16-inch ARP 2000 bolts, a popular choice for their reliability and clamping force in performance applications. The pistons are forged 2618 JE flat-tops, measuring 4.165 inches with a -5cc dish, which helps achieve a specific compression ratio when combined with your cylinder heads. This kit also includes plasma-moly file-fit piston rings, allowing for precise ring gap adjustment, and King XP rod and main bearings, known for their performance capabilities.
This assembly comes balanced from Eagle, saving you a significant step and ensuring your engine runs smoothly. Keep in mind that this part is not CARB approved and cannot be shipped to California. It's important to consult with your engine builder or refer to manufacturer specifications for proper installation and tuning, especially when dealing with high-performance components like these.
