About this part

Product Details

If you're rebuilding a Chevy 350 engine for serious performance, especially for racing applications, a balanced rotating assembly like this one from Eagle is a solid foundation. This assembly includes a forged crankshaft, connecting rods, pistons, rings, and bearings, all balanced together as a unit. This means less vibration and smoother operation at high RPMs, which is crucial when you're pushing the engine hard, whether that's on the track or with forced induction.

Eagle uses a forged 4340 steel crankshaft with a 3.480-inch stroke, paired with strong 6.000-inch H-beam connecting rods. These rods come with 7/16-inch ARP 8740 bolts, known for their reliability under stress. The pistons are forged 4032 aluminum from ICON, featuring a -3.7cc flat top design and a 4.060-inch bore size, ready for plasma-moly standard gap rings. King XP rod and main bearings are included to handle the load. This combination is built to handle the demands of racing, including nitrous and forced induction setups.

Because this assembly is pre-balanced, it simplifies the engine building process and helps ensure optimal performance and longevity. Keep in mind that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
