Erm thinking - the current Roadster 3,7 should have a 3,07:1 (according to current Morgan handbook) ratio WITH LSD (or other mind-widening ingredients in addition to make the sheer power groundable) !

IF yours has a 3,73:1 fitted, not only is your first gear useless (as on std. 3,7s), but so are 2nd (& 3rd, ...).... scared

It doesn´t matter how fast it becomes, but how it becomes fast. laugh2
