I think the factory did an excellent job of matching series gearing to
the engine. The Ashcroft kit raises the high range to be almost
identical to replacing the 4.7 diffs with 3.54 diffs. You can get away
with that if you run a bare bones 88 on the flatlands near sea level.
But an Ashcroft conversion has no business on a 109 or an 88 used in
mountain terrain or at altitude (unless you enjoy double clutching
down to second or first gear on inclines). 2.25 engines are well
matched to stock gearing and an overdrive with the ability to split
gears makes all the difference in the world at altitude or in mountains.
Add 50% or more HP to the Land Rover and suddenly the Ashcroft kit
becomes the preferred option. But if you are sticking with the 2.25L
boat anchor, get thee a Roverdrive.
I believe Wise Owl, Atlantic British, British Pacific and Rovers North
carry them in North America.
