Eagle Chevy 350 1Pc 3.750in Crank 5.700in I-Beam Rods 4.000in Pistons 153 Tooth FP Balanced Assembly

If you're building a street-driven Chevy 350 that runs on pump gas and isn't force-fed, this balanced rotating assembly from Eagle is a solid foundation. It's designed for naturally aspirated applications where reliability and consistent performance are key. This assembly includes a 3.750-inch cast crankshaft, 5.700-inch I-beam connecting rods fitted with 3/8-inch ARP 8740 bolts, and 4.000-inch hypereutectic KB flat-top pistons with a -7cc dish. This combination is balanced at the factory, so you can drop it into your engine block with confidence, saving you a significant step in the build process.

Beyond the core components, this assembly comes complete with plasma-moly file-fit piston rings, King SI rod and main bearings for proper oil clearance, a damper to control torsional vibrations, and a 153-tooth flexplate for automatic transmissions. The hypereutectic pistons are a good choice for street use, offering improved strength over cast pistons while remaining more budget-friendly than forged options. The inclusion of ARP bolts for the connecting rods signifies a step up in reliability for these critical components. This is a well-thought-out package aimed at making your engine build smoother and more dependable for everyday driving.

Keep in mind that this assembly is not CARB approved and cannot be shipped to California. It's important to verify fitment with your specific engine block and ensure all necessary machine work is completed before installation. This rotating assembly is a substantial piece for a performance street engine build.
