    Well an isuzu stage one does exactly 3200rpm at 100kmh. I don't believe they changed the gearing to the V8.
    I know this because 3200 is what the isuzu was governed to.
    The stage 1 should have the 1.4:1 high range transfer case ratio. So the diff is 3.54:1, top gear is 1:1 in the 4 speed. So measure from the ground to the centre of the wheel and you should be able to get a reason idea of the rpm you will be doing at any speed.
    84' 120" ute - 3.9 isuzu.

    Thanks

    Other than not being too good at Math , I can say that Big Red runs at 3200RPM at 100kmh and it is the V8

    Other landy ' experts' have told me this is not right but I think they base that on either V8 Rangies or V8 County's

    Revs at 100kph

    I have an isuzu stage one and had been told that the rev limiter was 118kph (although 100kph was as fast as i've been- my speedo is a bit flicky and dodgy and it is a bit noisy at 100)
    Apparently the isuzu ones have a different transfer ratio?
