Stop in for a cup of coffee

I’m gonna be running 4.10s in my dart. But with the t56, I should be around 2200-2400 rpms
For spirited street and "occasional" highway driving a 3.55 would be good. I find myself driving 2-4+ hours to bigger shows. All the rest are local within a few min. drive time. I am 65 and really don't need to smoke the tires a city block with a big engine and a big gear. A 273/4 and a 318/2 do me fine. Besides , I get almost 20 mpg with either car and both have plenty of pep.
