We have a 6.9 [1]that hovers around a 1000 revs @ 110k...and we just bought another older one [2] that revs at nearly twice that tach reading for the same speed...[his and hers]
1 is a really nice well kept machine and uses very little fuel for such an engine size..and still roars like a lion...the other ..2..even on gas uses a lot...
Is there some kind of automatic overdrive in some gearboxes??..optional rear end ratios etc..
Z..
