I think that would be a noticeable swap. 3.27 to 3.55 is a waste of time, though.

4.10/4.30 or go home.

Kidding, but if you plan on having the car around for a while, I think the 3.55’s would keep you happy.

I went from 3.23’s to 3.73’s and while noticeable, it wasn’t that big of a change. Go for the 3.73’s.

I think going from 2.73 to 3.55 will be good enough. I still want some kind of highway mileage.
