I have a TKO600 with .83 5TH and 3.54 Differential. Pulls strong 50mph and up. About 2600 RPM at 70MPH. Cruising on Ca freeways a down shift to 4TH is not required often. For my driving style the .64 required more time in 4TH..........Thats my 2 cents........Note that the engine is a Roush 427SR.........Good luck
