Eagle Chevy 350 1Pc 3.750in Crank 5.700in I-Beam Rods -18cc 4.040in Pistons Rotating Assembly

If you're rebuilding a Chevy 350 engine and aiming for more displacement and power, a balanced rotating assembly is a critical starting point. This assembly from Eagle is built for 1-piece rear main seal blocks and includes a 3.750-inch stroke crankshaft, 5.700-inch I-beam connecting rods, and pistons designed for a 4.040-inch bore with an -18cc dish. This combination effectively increases your engine's cubic inches, which is key to making more horsepower and torque.

Eagle has put together a well-built package here. The crankshaft is forged from 4340 steel, known for its strength and durability under high stress, making it suitable for performance builds. The I-beam connecting rods are also forged from 4340 steel and feature a 5.700-inch length, which is a common and effective length for many Chevy 350 performance applications. The included pistons are designed to work with these components, featuring a -18cc dish to help achieve a desired compression ratio when paired with appropriate cylinder heads. This assembly comes balanced, saving you a significant step and cost in the engine building process.

This rotating assembly is a solid foundation for a performance Chevy 350. Keep in mind that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed specifications and installation instructions for precise measurements and assembly procedures to ensure optimal performance and longevity of your engine build.
