The 1.7 Puma box however has a slightly taller 1st gear and a closer 3rd, 4th and 5th gear:

1st 3.15
2nd 1.93
3rd 1.41
4th 1.11

The 1.6 Zetec S, has a 4.25 Final Drive Ratio

The 1.25/1.4, has a Final Drive Ratio of 4.27.

The 1.7 Puma has a Final Drive Ratio of 3.82

People tend to go down the route of 1.6 Zetec-S ratios and the Final Drive from a 1.7 puma which is the same as an Ford Racing Puma box.
