Eagle Chevy 327 3.250in Crank 5.700in 5140 Steel I-Beam Rods 4.040in Pistons Rotating Assembly

This Eagle Pro Street rotating assembly gives you the core components for a robust Chevy 327 engine build. Inside this package, you'll find a 3.250-inch crankshaft, a set of 5.700-inch I-beam connecting rods made from durable 5140 steel, and pistons sized at 4.040 inches. These are the essential pieces that work together to convert the up-and-down motion of your pistons into the rotational force that powers your vehicle.

Eagle designed this Pro Street assembly with naturally-aspirated racing applications in mind. The 5140 steel I-beam rods are well-built for the stresses of performance driving, offering a strong and reliable connection between the pistons and the crankshaft. The crankshaft itself is precision-machined to ensure smooth operation and proper balance, which is crucial for high-RPM performance. The included pistons are sized for a 4.040-inch bore, a common size for many Chevy 327 builds, making this a convenient starting point for your engine project.

When putting together a performance engine, the rotating assembly is the heart of it all. Getting these components right from a reputable brand like Eagle sets you up for success. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. For optimal results, always refer to the manufacturer's installation instructions and consider professional balancing for your specific engine combination.
