About this part

Product Details

This rotating assembly from Eagle includes a one-piece rear main seal crankshaft with a 3.750-inch stroke, 5.700-inch H-beam connecting rods, and 4.060-inch pistons designed for a -10cc combustion chamber. This is a comprehensive package for rebuilding or upgrading the heart of your Chevy 350 engine, aiming for improved performance and durability.

The crankshaft is forged from high-quality steel, offering a strong foundation for high-horsepower applications. The H-beam connecting rods are also forged, known for their strength and ability to handle significant stress, making them a popular choice for performance builds. The included pistons are designed to work with the specific bore size and stroke of this assembly, and their -10cc dish volume is factored into achieving a target compression ratio when paired with appropriate cylinder heads. This assembly is balanced to reduce vibration and ensure smooth operation, which is crucial for engine longevity under demanding conditions. It's important to note that this assembly is not CARB approved and cannot be shipped to California.

When undertaking a project of this magnitude, it's always recommended to consult the manufacturer's detailed installation instructions. Proper balancing, clearances, and assembly techniques are critical for the success of your engine build. This rotating assembly is a significant step towards a more powerful and reliable engine, but it requires careful attention to detail during installation.
