Eagle Chevy 454 4.250in Crank 6.385in I-Beam Rods -3cc Flat Top 4.310in Pistons Balanced Assembly

This Eagle Pro Street balanced rotating assembly is built around a 4.250-inch forged 4140 crankshaft. This is a solid foundation for a high-performance Chevy 454 engine, especially if you're aiming for naturally-aspirated racing applications. The assembly includes 6.385-inch I-beam connecting rods made from strong 4340 steel, which are secured with 7/16-inch ARP 8740 bolts. These components are balanced as a set, meaning the critical rotating mass is already accounted for, saving you time and ensuring proper engine operation.

The pistons are forged 4032 aluminum from Mahle, featuring a -3cc flat top design and a 4.310-inch bore size. This piston choice is well-suited for naturally aspirated builds and works with the included plasma-moly file-fit piston rings. For the bearings, Eagle has specified King XP rod and main bearings, known for their durability and performance under load. This assembly is designed for serious performance builds where reliability and strength are paramount.

When assembling your engine, remember that the plasma-moly rings are file-fit, meaning they need to be gapped to your specific cylinder bore dimensions before installation. This ensures optimal sealing and performance. Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions for proper assembly and break-in procedures.
