3.91s in my 340 now!

I had 3:91's in my Duster back in the 80's, but they were too steep for me. I got tired of it winding up so high. 3:21's now with a 4-speed and it's perfect
Yeah, I hear that often from people regarding the 3.91s. To each their own, I guess. I am very happy with them. I don't do much highway driving, though.
