Product Details
Starting with a forged 4340 steel crankshaft featuring a 3.480-inch stroke, this balanced rotating assembly from Eagle is built for serious performance. It's designed to handle the demands of racing, including applications using nitrous oxide or forced induction. The assembly includes 6.000-inch H-beam connecting rods, known for their strength and reliability under high stress, secured with 7/16-inch ARP 8740 bolts. These rods are paired with Icon forged 4032 aluminum pistons, which are flat-topped with a -3.7cc dish to accommodate various compression ratios and feature plasma-moly standard gap rings for improved sealing.
The choice of materials and design elements here are crucial for durability and performance. The forged 4340 crank and H-beam rods offer a strong foundation, while the Icon pistons are well-suited for the thermal expansion characteristics needed in high-performance engines. King XP rod and main bearings are included, providing robust lubrication and wear resistance for the critical rotating components. This assembly comes balanced from the factory, saving you a significant step in the engine building process and ensuring smoother operation and reduced vibration.
This balanced rotating assembly is a substantial upgrade for a Chevy 350 engine, intended for builders who need a robust rotating assembly ready for demanding use. Please note that this assembly is not CARB approved and cannot be shipped to California. Always consult with your engine builder or refer to manufacturer specifications for proper installation and compatibility with your specific engine build.
