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

This Eagle rotating assembly is built for Chevy 400 engines, featuring a 3.750-inch crankshaft, 5.700-inch I-beam connecting rods, and -18cc dish pistons with a 4.185-inch bore. It’s a comprehensive package designed to form the heart of a performance or rebuilt engine, providing the core components for your bottom end.

The crankshaft is forged from 4340 steel, known for its strength and durability under high stress, making it a solid choice for builds that will see regular use or demand more power. Paired with these are the Eagle I-beam connecting rods, also forged from 4340 steel. I-beam rods offer a good balance of strength and weight, suitable for a wide range of performance applications. The pistons are designed with a -18cc dish, which helps to achieve a specific compression ratio when paired with the correct cylinder heads and deck height, and they are sized for a 4.185-inch bore. This assembly is a well-built foundation for anyone looking to rebuild or upgrade their Chevy 400 engine.

When installing this rotating assembly, it's important to ensure all components are properly balanced and clearances are checked according to manufacturer specifications.
