About this part

Product Details

Eagle is well-known for building robust engine components, and this balanced rotating assembly is a prime example of their commitment to performance. If you're building a Chevy 350 for serious street or strip duty, this assembly is designed to handle the demands of high-RPM operation and increased power output. It's a complete package that takes the guesswork out of matching critical rotating parts.

This assembly starts with a forged 4340 steel crankshaft featuring a 3.750-inch stroke, providing a solid foundation for increased displacement and torque. Paired with the crank are 6.000-inch H-beam connecting rods, known for their strength and reliability under stress. These rods are secured with 7/16-inch ARP 8740 bolts, a popular choice for their durability and consistent clamping force, especially important when dealing with nitrous or forced induction. The pistons are forged 4032 aluminum from Icon, featuring an inverted dome design with a -18cc dish to achieve a specific compression ratio when paired with your cylinder heads. They come complete with plasma-moly file-fit rings, allowing for precise ring gap adjustment to optimize performance and sealing. To ensure smooth operation and proper oil clearance, the assembly includes King XP rod and main bearings.

This rotating assembly comes balanced from Eagle, saving you a significant step and ensuring proper engine harmonics right out of the box. It's an excellent choice for builds aiming for significant power gains, including those utilizing nitrous oxide or turbochargers. Please note that this assembly is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning.
