About this part

Product Details

Eagle is well-known for building robust engine components, and this balanced rotating assembly kit for the Chevrolet 350 is a prime example of their commitment to performance. If you're building a high-performance or racing engine, especially one that will see nitrous or forced induction, this kit gives you the core components to get started right.

At the heart of this assembly is a 3.750-inch forged 4340 crankshaft, chosen for its strength and durability under demanding conditions. Paired with this are 6.000-inch H-beam connecting rods, which are known for their solid construction. These rods come equipped with 7/16-inch ARP 8740 bolts, a popular choice for their reliability in high-stress applications. The kit also includes forged 4032 Mahle pistons with a -5cc flat top design, intended for a 4.030-inch bore. For ring selection, you'll find plasma-moly file-fit rings, giving you the flexibility to set your ring gap precisely for your build. Rounding out the internal rotating components are King XP rod and main bearings, selected for their performance characteristics.

This assembly comes balanced from Eagle, saving you a significant step and cost in your engine build process. Please note that this kit is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning.
