Suggestions for a 318 build

Sorry, yea 3.55's 4.10's I can live with. Don't really know how much highway driving I'll be doing. This is my fun car. Sort of my cruise the B L V D car. I can always go to a higher ratio if I can't take the whine. 3000 stall converter and shift kit is in the future as well. Not so much that I will want to race everyone I see. Just don't want a Mopar to be smoked by a Honda if you know what I mean. I guess what you mean is how mean I want it. A good cam not too choppy and able to keep my power stuff brakes mostly! As far as drivability, well the wife may want to take it for a spin once in a while. Not a race car but not a grandma either.
