Eagle Chevy 454 4.250in Crank 6.385in H-Beam 43cc Dome 4.320in Pistons Rotating Assembly

If you're building a high-performance Chevy 454 engine for racing, especially with nitrous or forced induction, a strong rotating assembly is the heart of your build. This Eagle Competition Rotating Assembly is designed to handle the extreme stresses that come with serious power. It's a complete package that gives you the core components needed to build a robust engine capable of competing.

This assembly starts with a forged 4340 crankshaft with a 4.250-inch stroke, providing the foundation for increased displacement and torque. Paired with this are 6.385-inch H-beam connecting rods, known for their strength and reliability under high loads. These rods are secured with 7/16-inch ARP 8740 bolts, a name trusted for their quality and clamping force in performance applications. The pistons are forged 2618 aluminum from Mahle, featuring a 4.320-inch bore and a 43cc dome to achieve a specific compression ratio, crucial for optimizing power output with your chosen cylinder heads and camshaft. The assembly also includes plasma-moly file-fit piston rings, allowing for precise gap setting to match your engine's bore and intended use, which helps with sealing and oil control. Finally, King XP rod and main bearings are included, offering excellent durability and performance for high-stress engine operation.

This is a comprehensive rotating assembly, meaning you get the critical internal engine components in one package. While it's built for competition, remember that it 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, ring gapping, and assembly procedures to get the most out of this powerful rotating assembly.
