Product Details
This is a complete rotating assembly from Eagle for a Chrysler 440 engine. It includes a 3.750-inch stroke crankshaft, 6.760-inch H-beam connecting rods, and a set of 4.360-inch, -12cc step dish pistons. This assembly is designed to give your 440 a significant displacement increase, making it a solid foundation for a high-performance build. If you're looking to rebuild your big-block Mopar for more power, a balanced rotating assembly like this is a critical first step.
Eagle is known for producing well-built internal engine components, and this assembly is no exception. The crankshaft is forged from high-quality steel for strength and durability under high stress. The H-beam connecting rods are also forged, offering a strong and reliable connection between the pistons and the crankshaft, capable of handling increased cylinder pressures and RPMs. The pistons are designed with a -12cc step dish, which will affect your compression ratio depending on your cylinder head volume. This assembly is balanced, meaning the crankshaft, rods, and pistons are weighted to work together smoothly, reducing vibration and improving overall engine longevity. This is a crucial detail for high-performance applications where balance is key to preventing premature wear.
When building a performance engine, using a balanced rotating assembly from a reputable manufacturer like Eagle simplifies the process and ensures that the core components are designed to work together. This assembly is intended for custom engine builds where increased displacement and power are the primary goals. Please note that this part is not CARB approved and cannot be shipped to California. Always consult with your engine builder or refer to the manufacturer's detailed specifications for exact compression ratio calculations and recommended clearances for your specific application.
