Hello, Its kinda hard to ask this question in your local community when its mostly Mustangs I thought maybe I would have better luck here. I've been wanting to get an opinion on the Scat Pack and 392. I would get a Hell Cat but I commute so thats probably not the best option. What is the main difference? I currently have a Charger but Ive been thinking of switching over to the Challenger. What are some of the averages in mpg?
