When you're building a serious Chevy 454 engine, starting with a well-balanced rotating assembly can save you a lot of headaches down the road. This Eagle Pro Street assembly gives you the core components you need to get your build underway. It includes a forged 4.000-inch stroke crankshaft made from 4340 steel, paired with 6.135-inch long I-beam connecting rods. These rods are also forged from 4340 steel and come equipped with 7/16-inch ARP 8740 bolts, known for their strength and reliability in performance applications.

The pistons included are forged 4.032-inch Icon flat-tops with a -3cc dish, designed for a 4.250-inch bore. These are matched with plasma-moly file-fit piston rings, giving you the flexibility to achieve a precise fit for optimal sealing. To round out the assembly, you get King XP rod and main bearings, which are well-regarded for their performance and durability. This entire rotating assembly comes balanced from Eagle, a crucial step that reduces engine vibration and improves overall performance and longevity.
