Eagle Chevy 350 3.480in Crank 6.000in I-Beam Rods -3.7cc Flat Top 4.030in Pistons Balanced Assembly

Starting with a 3.480-inch forged 4140 crankshaft, this balanced rotating assembly from Eagle is built for serious performance in your Chevy 350. It's designed for naturally-aspirated racing applications where every component needs to work together reliably under stress. The assembly includes 6.000-inch I-beam connecting rods made from strong 4340 steel, which are secured with 7/16-inch ARP 8740 bolts. These rods are a popular choice for their balance of strength and weight, making them suitable for high-RPM use.

The pistons are forged 4032 aluminum from Icon, featuring a -3.7cc flat top design and a 4.030-inch bore size. These pistons are paired with standard gap plasma-moly rings, which help ensure a good seal between the piston and cylinder wall for optimal compression and oil control. To complete the rotating assembly, King XP rod and main bearings are included, offering robust performance and durability. This entire package comes balanced from Eagle, saving you a significant step in the engine building process and ensuring your new assembly is ready for installation.

This assembly is a solid foundation for a performance-oriented Chevy 350 build. Please note that this part is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures.
