You know what's wrong with NASCAR these days? Two things: the fans no longer drink beer from steel cans, and nobody races inline-six flatheads! Oldsmobile and Chrysler had new overhead-valve V8s in the early 50s, but Hudson Hornets equipped with 308-cubic-inch, twin-carb (called "Twin-H") flathead six engines utterly dominated NASCAR during the era. You can get a 308 equipped with a 4-71 supercharger nowadays, in case your Hornet needs even more power! Make the jump for the sound of the Hudson six. [Collector Car Market]
