The hemi Darts and Cudas have several special heads up races called 'Hemi Shoot Outs' at selected races that are sponsored by Mopar and others that are run in conjunction with qualifying. The ones I can think of are all the Sportsnationals, Indy, Las Vegas- Mopars at the strip and Mission,B.C. There are more I'm sure.It has to be one of the best shows going.
You can go on the NHRA website and look under the tab for schedules and see what National events will run Super Stock. And if Super Stock Class is contested you will see some heads up racing of any AH cars that are there for that race. Even if class is not contested there may still be an AH Dart or Cuda at the race. But the Hemi Shootouts will attract the largest gathering of the cars to see. And it is well worth the trip to see the show. One of the best times is always at the sportsnationals in Belle Rose coming up in April.
