Eagle Chevy 454 4.000in Crank 6.135in H-Beam 18.3cc Dome 4.320in Pistons Rotating Assembly

If you're building a high-performance Chevy 454 engine, this Eagle competition rotating assembly is a solid foundation. It includes a forged 4.000-inch crankshaft, 6.135-inch H-beam connecting rods with 7/16-inch ARP 8740 bolts, and 4.320-inch forged 4032 Icon pistons with an 18.3cc closed chamber dome. This assembly is designed to handle the demands of racing, including nitrous and forced induction applications.

The forged 4340 steel crankshaft offers improved strength and durability over cast cranks, making it suitable for high-stress environments. The H-beam connecting rods are well-known for their strength and are paired with ARP 8740 bolts, a popular choice for their reliability in performance builds. The Icon pistons are forged from 4032 aluminum, which offers good thermal expansion properties for a tighter piston-to-wall clearance, and feature a dome design that contributes to compression. This assembly also comes with plasma-moly file-fit rings, which allow for precise gapping to match your specific cylinder wall finish and bore size, and King XP rod and main bearings, known for their robust performance in demanding applications.

This rotating assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. Ensure you have the necessary tools and expertise for installation, or consult a professional engine builder. This is a critical component for anyone looking to build a powerful and reliable big-block Chevy engine.
