3:55's are a bit much for the highway on long trips. If you run primarily around town. They are an excellent gear. You can find RPM calculators by doing a search online.

It will be a bit on the low side due to converter slippage on the automatic. -- Mark Price markprice242ATadelphia.net Morgantown, WV ---- Kerry Flanagan <kflan5621@xxxxxxxxx> wrote: > I know this isn't an easy find, but I'm looking for a set of 3:55 gears > for a 65 AMC Classic model 20 rear end.
