My high range is.....1.112 to one........5.57 diffs
The standard 101 high range was a slightly lower ratio

Diana, have you considered a Chrysler Hemi Six 265 as a repower? I have had experience with these in Series III's and have long considered this engine to be the bst petrol enine repopwer for a Series. The block casting is only 1/4" longer than a red Holden. They were made using then state of the art thin wall foundry technology and are quite light in comparison to the usual early English vertical school of engine design. Have big valves and big ports standard. Bung on A Redline 4 barrel manifold and Rochester Quadrajet with CM Valiant split exhaust headers feeding twin 2 1/4" system, clean out the ports, and fit or grind a pre-emission control camshaft and you have over 200 bullet proof and tractable hp that can rev like a turbine.

Yes I have, as a 1970's vehicle the 265 is getting hard to find parts for these days. In fact it had a 215 Hemi from a Dodge when it arrived. The big problem is finding a gearbox that will stand up to a re-power and then mate that to an engine. The options are use Toyota engine and transmission, mate something like a New Venture 4500 to the Land Rover transfer and use a GM or Dodge engine or use a later Rover V8 and gee I love the sound of a V8 :D:D:D:D

Parts are no problem whatsoever. There are a number of specialist after-market dealers. Lots of high performance pieces. Pistons are the same as one of the US V8's. Once rebuilt they live virtually forever unless you do something completely stupid like run them without oil or water. LT85 should live behind one. It is the 4BD1 that destroys them with low speed torque and big bang impulses. I offered up a V8 LT85 bell housing to a hemi this morning and a pretty simple sandwich plate should mate them together.

You know guys, as interesting as all this is I'm still not sure we have answered the original question. Which gearbox is where.

So inconsideration of the all the posts, and what I should probably use:
- Which year model County had the V8 and LT85/LT230?
- In the V8 Countys with LT85/LT230 did they have the Defender 1.41:1 hi transfer ratio?
- In the Disco models when did the 3.9V8/R380 start and did they have the LT230 CDL and mechanism?
- When did the Defenders get the 3.9V8 and R380?
From that I can start looking either for a donor vehicle or even assemblies.

Cheers

In the Disco models when did the 3.9V8/R380 start and did they have the LT230 CDL and mechanism? 94, Yes
When did the Defenders get the 3.9V8 and R380? They didn't

According to the ratios given in the Australian Supplement TP1107B the V8 with LT85 & LR230T had the 1.41 high range. They state the overall ratio in 4th high is 4.99:1 which is 1.41 x 3.54. The transfer I have sitting on the ground here is from a V8 LT85 and has a 1.41 high range. Dave Blknight swapped my transfer over when he changed the boxes. I have a surplus perfectly good 230 transfer with 1.41 high range if anyone is interested.

The LT85 was introduced in 1985/6 in all countys, replacing the LT95. Was never an option. The only exception to this was the military 110s and 6x6s - which kept the LT95 (even the extra batch ordered in the early 90's).

No OZ defenders ever had a V8, only some limited edition specials made for UK and US markets (I think about 5000 vehicles in the US).

My understanding there was only 22 V8 county landies and they were sold to the goverment to pull some sort of Bi centenial propagander trailer.

OMG

I didn't know that Defenders didn't have the V8 - shows how much I've been watching. I just thought everyone wanted diesels!

As an aside, Have you heard todays news "According to some members of the UN World Food Programme, the use of bio-fuels for vehicle engines in developed countries is genocide to poor people of developing nations". Bio-Diesel is no longer green! :(

Looks like I have to find a Bi-Centennial 110 and steal its transmission. :angel:

Thanks everyone.
