Eagle Chevy 454 4.000in Crank 6.135in H-Beam -3cc Flat Top 4.310in Pistons Balanced Assembly

What you get in this balanced rotating assembly is a complete package ready to build a strong Chevy 454 engine. It includes a 4.000-inch forged 4340 crankshaft, 6.135-inch H-beam connecting rods with 7/16-inch ARP 8740 bolts, and 4.310-inch forged 4032 Icon flat-top pistons with a -3cc dish. This assembly also comes with plasma-moly file-fit rings and King XP rod and main bearings, all balanced and ready for installation.

This assembly is built for serious performance, perfect for racing applications and capable of handling nitrous and forced induction. The forged 4340 crank and H-beam rods are known for their strength and durability under high stress. The Icon pistons are forged from 4032 aluminum, which offers good thermal expansion properties for a tighter piston-to-wall clearance, and the flat-top design with a -3cc dish is ideal for achieving specific compression ratios when paired with the right cylinder heads. The inclusion of ARP 8740 bolts for the connecting rods means you're getting strong, reliable fasteners that are a step up from standard hardware.

The plasma-moly file-fit rings give you the flexibility to set your ring gap precisely for your engine's bore and intended use, which is crucial for optimal performance and sealing. King XP bearings are designed for high-performance applications, offering improved load-carrying capacity and durability. This balanced assembly means the rotating components have been precisely weighted and balanced at the factory, saving you a significant step and ensuring smooth operation and reduced vibration in your engine.
