Eagle Chevy 454 4.000in Crank 6.135in I-Beam Rods -3cc Flat Top 4.280in Pistons Balanced Assembly

Starting with a 4.000-inch cast crankshaft, this balanced assembly from Eagle is built for street performance. It's designed for pump gas, naturally aspirated Chevy 454 engines, making it a solid choice for street vehicles that see regular use. The goal here is to give you a well-built rotating assembly that's ready to go, saving you time and ensuring critical components are matched correctly.

The assembly includes 6.135-inch I-beam connecting rods, which are strong and reliable for street applications. These rods are paired with 7/16-inch ARP 8740 bolts, known for their strength and ability to handle the stresses of a performance engine. For the pistons, you get forged 4032 Mahle flat-top pistons with a -3cc dish, designed for a 4.280-inch bore. These are paired with plasma-moly file-fit rings, giving you flexibility during installation to achieve a perfect seal. King rod and main bearings are also included, providing good wear resistance and proper oil clearance for the crankshaft.

This is a balanced assembly, meaning the crankshaft, rods, and pistons have been balanced together at the factory. This step is crucial for reducing engine vibration and improving overall smoothness and longevity, especially at higher RPMs. While this assembly is intended for street use, please note it is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures.
