Eagle Chevy 350 3.750in Crank 5.700in I-Beam Rods -7cc Flat Top 4.060in Pistons Balanced Assembly

If you're rebuilding the heart of your Chevy 350 for street use, a balanced rotating assembly like this one from Eagle can save you a lot of time and ensure your engine runs smoothly. This assembly is designed for pump gas, naturally aspirated street vehicles, making it a solid choice for many common V8 builds. Getting a balanced assembly means the critical rotating components—crankshaft, connecting rods, pistons, and rings—have been precisely weighted and matched to minimize vibration and ensure proper engine operation right out of the box.

This particular assembly features a 3.750-inch cast crankshaft, paired with 5.700-inch I-beam connecting rods. These rods are secured with strong 3/8-inch ARP 8740 bolts, which are a significant upgrade over stock fasteners. For the pistons, you get Hypereutectic KB flat-top pistons with a -7cc dish, designed for a 4.060-inch bore. These are matched with plasma-moly standard gap rings. To top it off, the assembly includes King rod and main bearings, known for their reliability in street applications. This combination aims for a good balance of performance and durability for everyday driving.

Because this assembly is balanced, it simplifies the engine building process, as you won't need to send these components out for balancing separately. However, it's important to note that this assembly 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 to get the most out of your new rotating assembly.
