Eagle Chevy 305 3.480in Crank 5.700in I-Beam Rods -3cc Flat Top 3.766in Pistons Rotating Assembly

This Eagle rotating assembly is built for Chevy 305 engines, featuring a 3.480-inch crankshaft, 5.700-inch I-beam connecting rods, and 3.766-inch, -3cc flat-top pistons. It’s a comprehensive package designed to form the core of your engine's short block, ready for assembly into your project vehicle. This assembly is a solid choice for builders looking to establish a strong foundation for a performance or rebuilt engine.

The crankshaft in this kit is forged from durable steel, providing the strength needed to handle increased cylinder pressures and RPMs. Paired with the I-beam connecting rods, which are also forged for enhanced durability, this assembly is well-suited for applications that go beyond stock specifications. The flat-top pistons are designed with a -3cc dish, which is a common configuration for many performance builds, helping to achieve a desired compression ratio when paired with appropriate cylinder heads. The 3.766-inch bore size is specific to the 305 application, ensuring a proper fit within the engine block.

When assembling this rotating unit, pay close attention to bearing clearances and piston ring gap settings, as these are critical for engine longevity and performance. It's recommended to consult a detailed engine building manual or seek professional advice for precise installation procedures. This assembly does not include bearings, rings, or the oil pump, so be sure to source those separately to complete your short block build. Please note that this assembly is not CARB approved and cannot be shipped to California.
