Eagle Chevrolet 427/454 Balanced Competition Rotating Assembly Kit

Forged from 4340 steel, the Eagle 4.250-inch crankshaft in this rotating assembly is built to handle the demands of racing, including nitrous and forced induction applications. This kit is specifically balanced for Chevrolet 427 and 454 big-block engines, making it a solid foundation for a high-performance build. The robust construction ensures reliability when you're pushing your engine to its limits.

Complementing the crankshaft are 6.385-inch H-beam connecting rods, secured with 7/16-inch ARP 8740 bolts. These rods are known for their strength and ability to withstand high RPMs and significant cylinder pressures. The kit also includes Mahle forged 4032 pistons with a -3cc flat top design and a 4.280-inch bore, paired with plasma-moly file-fit rings. This piston and ring combination is designed for optimal sealing and performance. For the bottom end, King XP rod and main bearings are included, offering excellent durability and smooth operation under stress.

This balanced rotating assembly is a comprehensive package for anyone rebuilding or building a performance Chevrolet big-block engine. Please note that this assembly is not CARB approved and cannot be shipped to California. It is also subject to California's Proposition 65 warning.
