Eagle Chevy 350 1Pc 3.480in Crank 5.700in H-Beam -5cc Flat Top 4.060in Pistons Balanced Assembly

Eagle is well-known for building robust engine components, and this balanced rotating assembly is a prime example of their commitment to performance. This assembly is designed for Chevy 350 engines and is ready to handle the demands of racing, including applications using nitrous or forced induction. It’s a complete package that simplifies building a strong foundation for your performance engine.

At the heart of this assembly is a forged 4340 crankshaft with a 3.480-inch stroke, paired with 5.700-inch H-beam connecting rods. These rods are secured with 7/16-inch ARP 8740 bolts, known for their strength and reliability under high stress. The pistons are forged 4032 Mahle units, featuring a -5cc flat top design and a 4.060-inch bore size, which are crucial for achieving the desired compression ratio. The assembly also includes plasma-moly file-fit rings, giving you the flexibility to set your ring gap precisely for optimal performance and sealing. For the bottom end, King XP rod and main bearings are included, offering excellent durability and smooth operation.

This balanced assembly means the critical rotating components have been precisely weighted and matched at the factory, saving you time and ensuring proper engine balance from the start. This is especially important for high-RPM applications where imbalance can lead to premature wear and catastrophic failure. Please note that this assembly is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning.
