Eagle Chevy 400 3.480in Crank 6.250in H-Beam 6.2cc Dome 4.155in Pistons Rotating Assembly

This Eagle Competition Rotating Assembly gives you the core components to build a robust Chevy 400 engine. Inside this package, you'll find a 3.480-inch forged 4340 crankshaft, ready to handle serious power. It's paired with 6.250-inch H-beam connecting rods, which come equipped with 7/16-inch ARP 2000 bolts for a strong and reliable connection. The assembly also includes 4.155-inch forged 2618 JE pistons featuring a 6.2cc dome, designed to work with your cylinder heads. You also get plasma-moly file-fit piston rings, allowing for precise gap adjustment to match your engine's bore and intended use, along with King XP rod and main bearings to ensure smooth rotation and proper oil clearance.

This assembly is built for demanding applications, including racing use with nitrous or forced induction. The forged 4340 crankshaft and H-beam rods are well-built for strength and durability under high stress. The JE pistons are forged from 2618 aluminum, a material known for its resilience in high-performance engines. The inclusion of ARP 2000 bolts further reinforces the connecting rod assembly, providing a secure clamp load. The file-fit rings offer an advantage for tuners who need to dial in piston-to-wall clearance for optimal performance and sealing, especially in boosted or nitrous applications. King XP bearings are chosen for their robust construction and ability to maintain oil film under extreme loads.

When building a high-performance Chevy 400, a strong rotating assembly is the foundation. This Eagle kit provides the essential, well-built components to get you started. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and assembly procedures to ensure optimal performance and longevity.
