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

If you're rebuilding the heart of your Chevy 350 for street use, this balanced rotating assembly from Eagle is a solid foundation. It's designed for pump gas and naturally aspirated applications, meaning it's built to handle the demands of everyday driving and spirited cruising without needing exotic fuel.

This assembly starts with a 3.750-inch cast crankshaft, paired with 5.700-inch I-beam connecting rods. These rods are secured with 3/8-inch ARP 8740 bolts, a strong choice for reliable performance. The pistons are Hypereutectic KB Claimer flat tops, sized at 4.000 inches, and come with plasma-moly standard gap rings. King rod and main bearings are included to ensure smooth operation and proper clearances. The entire assembly is internally balanced with a 153-tooth flexplate, simplifying installation and ensuring it's ready to go right out of the box.

This rotating assembly is FP balanced, which means it's precisely weighted at the factory to reduce vibration and improve overall engine smoothness. This is a critical step for engine longevity and performance, especially in a street-driven vehicle. Please note that this assembly is not CARB approved and cannot be shipped to California.
