The question of the day: Stick with auto or go auto to stick?

I'm running a very mild 360 in a 1968 Barracuda, and all I want is the ability to hammer gears and still get decent mileage. My car is very much a daily to driver that gets it's legs stretched between stoplights and on the highway, so close-ratio gear crashing isn't completely necessary. I don't know what you plan on using your car for, but just remember that there are overdrive 4 speeds.
Well, I daily drive mine over half the time, usually in good weather, I drive the beater Honda during winter typically. I do long distance cruises (500+ miles) a few times a year. I will take it to the track maybe once or twice a year. I currently have 3.21 gears with 26.5" diameter rear tires. (245/60R15) Which is has done me good so far.
I did have 3.55 rear gears at one time. (long story, lets just say some idiot in a shop didn't install the pinion correctly). These gears were a little more "fun."
