Wait you're going to perform a back road drag race between a Nissan Titan pick-up truck and an old Challenger? How do conversations even come up like this?
But anyway, Dodge cited the 383 R/T at 14.3 in the quarter mile. Edmunds tested the Titan with a 15.3 quarter mile. So the Challenger is faster on paper, however there are so many different factors that play into a drag race, especially one "outside the town limits" it would be hard to say.
