Ok, I live in Calif. now but I lived in Az for 3 years before I got my challenger. I have thought about moving back one day but was always worried about the smog reg. As I recall there cut off is 1968. What has to be done to run a 73 E-body in Arizona?
I am not going back any time soon, but if I need to I don't want to be screwed. Any tips for AZ. reg on a challenger?
