Drag racing...where to start

Ok gang
As I am almost finished with my military career (14+ served) (6 ish to go) I think Id like to maybe do a little racing as I look at retirement. To get started in the sport what do you all suggest? Buying a car from someone is not an option, im very particular about ensuring things are just right (and safe) in my eyes before I do anything. Id like to run a Duster and it would be a race car only. No street time. What class? How do I research this? Thank you all FABO:glasses7:
