Some opinions please

I'm getting to the point where I need to make a decision on gear ratio. Here is the setup and intended use. 68 Valiant mild 440, 727, 2400-2800 stall converter say a 26" tire for cruising hot rodding of coarse and hwy use also, and I mean 80-85mph. Its also going to have A/C so I kept the cam size down for a decent idle. I have enough parts to build a 3.55 or a 3.23 which I'm leaning toward. I could throw 2.94 or a 2.76 in for long trips and re gear to even a lower set for in town but I'd kinda like to keep it simple with a happy medium, Your thoughts?
