Eagle Chevy 400 3.750in Crank 6.000in H-Beam 4cc Dome 4.125in Pistons Rotating Assembly

Eagle is well-known for making strong internal engine components, and this Competition Rotating Assembly is a prime example of their commitment to performance. If you're building a Chevy 400 for serious street or track duty, this assembly is designed to handle the demands of high-horsepower applications, including those using nitrous oxide or forced induction like turbochargers or superchargers.

At the heart of this assembly is a 3.750-inch forged 4340 crankshaft, chosen for its strength and durability under extreme stress. Paired with this are 6.000-inch H-beam connecting rods, which are also forged from 4340 steel and secured with 7/16-inch ARP 8740 bolts – a popular choice for their reliability in high-stress builds. The pistons are forged 4.125-inch units from Mahle, featuring a 4cc dome and made from 2618 aluminum, a material known for its expansion properties under heat. This assembly also includes plasma-moly file-fit piston rings, allowing for precise gap setting to match your specific engine build, and King XP rod and main bearings to ensure smooth rotation and proper oil clearance.

This rotating assembly is a comprehensive package for anyone looking to build a robust and powerful Chevy 400 engine. Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
