The Chevrolet Series AC International was a family of early cars introduced in 1929. The Series AC International, also known as the International, was powered by a new 3.2L inline six engine known as the 'Stovebolt Six.' A wide range of open and closed body styles were available, including tourer, truck, sedan, and coupe. Chevrolet only offered the AC International for the 1929 model year before replacing it with the Series AD Universal.
