[Tigers] 0.81 'overdrive' gearing

[Ron Fraser]

Yes, there were 2 ratios available.

There is an article in the September 1982 Hot Rod magazine with Ford part
numbers for most if not all the internal parts.
The article is basically about converting an overdrive transmission to
direct drive.

6 cyl has 20%	3.29	1.84	1.00	.80
8 cyl has 30%	3.07	1.72	1.00	.70

Randy,
       I have a friend who has a Mk-2 and he uses that transmission.  When
he
first installed it he had its original 2.88 differential gears and the car
was WAY overgeared, so he changed to a 3.07 gearset and he says it works
well.
Personally, I would not want a car that has a 1st gear, a 2nd, a 4th and a
5th
gear (essentially).  Also, from what I was told there were two different 4th

gear (overdrive) ratios available using that setup.
