Agreed. I'm running a 3.50 trac loc and 26" tires and it's fine. For freeway cruising I'm usually in the slow lane at 65 ish since even then I'm spinning 3,000+ RPM on the tach. It's not overly high RPM but my car eats a LOT of fuel at speed so I'm only trying to conserve a little when I can. As it is I'm under 10 MPG freeway, so it helps!With the 8" rear and a 26" tall tire i would look for a 3.55 or 3.40 ratio without overdrive.
