Hi Nevin:

The earlier MGB 3 synchro gearbox maybe a benefit regarding less power
consumed, however; a 3 synchro "D" type overdrive has an extermely small
cone clutch in comparison to the later "LH" type. The average "LH" type
cone clutch will out last a "D" type by a factor of twice.You must trade
off the higher maintenance cost to lower fuel economy. So the issue of
fuel cost is insignificant.

                                                                Good Luck: Rich
