   right then boffins here's the question.
   
   If you had a ma box with the following spec:
   
   1st=3.417
   2nd=1.950
   3rd=1.360
   4th=1.054
   5th=0.850
   reverse=3.583
   final drive=3.444
   
   and you swaped out the final drive for one of 3.765:1 what would the results be? all assuming power is lets say 170@crank.

   you would shorten the ratio's
   
   the acceleration would be a little quicker and you'd lose top speed.

   In other words through each gear the car would accelerate quicker than before, most likely shortening your 0-60 time because the gear ratios are shorter i.e. each gear will not last as long but then it will accelerate harder as a result.
   
   However the top speed of your car would not be as high. You may lose a few MPH of your cars top speed.
   
   Does that help?
