Eagle Chevy 454 4.250in Crank 6.385in H-Beam 23cc Dome 4.350in Pistons Rotating Assembly

This is a complete rotating assembly from Eagle, designed for serious performance builds in Chevy 489 big block engines. It includes a forged crankshaft, connecting rods, pistons, rings, and bearings, all balanced and ready to be installed. This assembly is built to handle the demands of racing, including applications using nitrous oxide or forced induction, making it a solid foundation for a high-horsepower engine.

At the heart of this assembly is a 4.250-inch forged 4340 steel crankshaft, known for its strength and durability under extreme stress. Paired with this are 6.385-inch H-beam connecting rods, which are a popular choice for their robust design and ability to withstand high RPMs and significant cylinder pressures. These rods come equipped with 7/16-inch ARP 8740 bolts, a well-regarded fastener known for its reliability in high-performance applications. The pistons are forged 4032 aluminum with a 23cc dome, designed for a 4.350-inch bore, and come with plasma-moly file-fit rings. This piston and ring combination is chosen for its ability to seal well under high boost or nitrous conditions. Finally, the assembly includes King XP rod and main bearings, offering improved lubrication and wear resistance for critical rotating components.

This rotating assembly is a comprehensive package for anyone building a performance engine. It's important to note that this part is not CARB approved and cannot be shipped to California. Ensure you consult with your engine builder or refer to manufacturer specifications for proper installation and balancing procedures, as these are critical steps for the longevity and performance of your engine.
