Indiana asphalt oval

Yes, several, but none that are running karts currently (that I am aware of.)
You might check out the MACKS series, which runs LO206 engines on champ karts on pavement stock car tracks around the area. There are several youtube videos as well as facebook page and @Scott Carson on here can tell you more.
