About this part

Product Details

If you're building a high-performance Chevy 400 engine for serious competition, this Eagle rotating assembly is a solid foundation. It's designed to handle the extreme demands of exotic fuels, heavy nitrous use, and high boost applications. This kit includes everything you need to get your engine's bottom end rebuilt with strong, reliable components.

At the heart of this assembly is a forged 4340 steel crankshaft with a 3.875-inch stroke, which helps increase displacement and power potential. Paired with it are 6.000-inch H-beam connecting rods, known for their strength and durability, secured with 7/16-inch ARP 2000 bolts. The pistons are forged 2618 JE units, featuring a -10.8cc dome to achieve a specific compression ratio with your cylinder heads, and they come with plasma-moly file-fit rings for a good seal. King XP rod and main bearings are included to ensure smooth rotation and proper oil clearance.

This is a well-built assembly intended for engines pushed to their limits. Please note that this assembly is not CARB approved and cannot be shipped to California. It's recommended to consult with your engine builder or refer to manufacturer instructions for proper installation and balancing procedures, as rotating assemblies require precise balancing for optimal performance and longevity.
