Chevrolet believe it or not, had a overhead valve V8 engine from 1917 to 1919.It was in the Chevrolet model D.It had nickel plated valve covers on it.
Many years before Ford had the famous Flathead V8.Chevrolet also has a air cooled engine in 1923 called The Copper Cooled.Just think,if the Chevrolet V8 of 1917 had been sucessful,there might not have been a Ford Flathead V8 or Chevy inline 6 cylinder.
