The Jeep Tornado engine was the first post-World War II U.S.-designed mass-produced overhead cam (OHC) automobile engine. The 230.5 cu in (3.78 L) hemi-headed straight-six was introduced in mid-year 1962, and replaced the flathead "6-226" Willys Super Hurricane that was in use since 1954.
The Tornado engine was also manufactured in Argentina by Industrias Kaiser Argentina (IKA) from 1965 until 1973.
