I briefly considered this box when I built my 110

I was dismissed for a number reasons

1) I didnt need an overdrive
2) the later models are electronic shift so no good for racing
3) some complications with the overdrive being engaged and activated which Isuzu Rovers post talks about
4) rare as hens teeth
5) cost to buy
6) cost to modify and parts scarce
7) The rover 727 runs on an angle and wasnt sure the 4 speed coudl do it


A 727 has no end of drums, bands, valve bodies etc that can be used in high HP applications and I still had problems in the early days nothing is bullet proof or a stright bolt inwhen conversions are concerned

However Im looking at doing a tow car maybe a defender 130 with a 427 ls7 and this box is being considered. Very early days yet and with the trailer not turning up may forget about it until much later let me know how you go if you end up using one
