i only watch the S.E,G,A events anymore .. South Eastern Gassers Association i believe .. they have a small block class .. a big block class and even are starting a mini engine class called H gas ..there are fords . chevys and dodges that compete at every event and the winners are spread around amoungst all brands '' .. yeah the Quadra family all run mustangs in pro stock but they are still chevy powered .... rules should be amended after every race to keep the same people ( Erica Enders ) from dominating .. the previous event winner should have to add penalty pounds at the next event ..
