My next built is a 71 Charger 500 with a Nascar theme for the highway and I was thinking of running 2.94s or even 2.76s behind a 440. It's an auto so it is my way of getting and overdrive, I figure the 440 should have enough torque to plus it no to mention it wont be a red light racer. But, yes, it will still need to get out of it's own way for me to be happy with it.
