Will I regret change to 3.55s from 2.76s

Not everyone needs to cut 1.7 60 ft times at every stop sign. In fact, many (me included) like highway speeds and not that I worry too much about mpg, it is impactive. I pull my car trailer with a classic. I have taken vacations (many) in classics. So to me, it depends on the use of the car. Only the owner will know that.
