Eagle Chevy 400 3.750in Crank 5.700in I-Beam Rods -18cc 4.185in Pistons Balanced Assembly

Eagle Specialty Products has a long history of building strong rotating assemblies for performance engines. This balanced assembly is built around a 3.750-inch stroke crankshaft, paired with 5.700-inch I-beam connecting rods. The pistons included are -18cc dish style, designed to work with the crankshaft and rod combination to achieve a specific compression ratio for your Chevy 400 application.

This assembly comes balanced from the factory, saving you a significant step in the engine building process. The I-beam connecting rods are a well-built choice for many performance builds, offering a good balance of strength and weight. The crankshaft is forged, providing the durability needed for higher horsepower applications. The pistons are cast aluminum, a common material for performance street engines that balances weight and cost.

When building a performance engine, a balanced rotating assembly is crucial for smooth operation and longevity. This Eagle assembly takes the guesswork out of matching components like the crank, rods, and pistons, and the balancing service ensures it’s ready for installation. Please note that this assembly is not CARB approved and cannot be shipped to California.
