Well I have 33's and 3:55 so I'm thinking about changing out for the 4:10's for some more power in towing. I have the Dana 70 rear and Dana 60 front as per build sheet. I'm runnin 2000 RPM's at about 70 in OD. Also remember I have a V10 so 3800 RPM is about redline. At 68 on the OD I'm runnin 75 MPH so I'd like to get back to having it right on cause nobady makes a tuner but B&G?
