I've been looking around for a cheap V8 donor vehicle and rusty Discoverys look like good value. My question is, can you use the gearbox in a rear wheel drive car or would I need an alternative?
Thanks

If you search around the "garage" section there's a thread by a chap who mounted a Ford F100 truck body onto a stock Range Rover chassis. It looked pretty good and if I remember right he kept the 4 X 4. Now i don't know how similar the Range Rover and Discovery chassis are but it should be some usefull reference material.

(sorry can't find the actual thread right now but if I find it later I'll post the link here)

from memory, the 'classic' range rover, series 1 & possibly series 2 (td5) disco's are the same chassis (the td5 normally has air suspension on rear axle, but can also get coil spring conversion if it fails, which is common) ... 100" wheelbase (from memory) & not to be confused with the seies 2b forward control chassis.
if you wanted to put the engine & transmission into another vehicle, you'd need to have the transfer box modified to just 2wd & you can have it locked in high range as a cheaper option to having new gears fitted.
depending on the condition of the disco chassis, then i'd agree that doing a body swap (if pickup or van) would probably be the easier option.
if it's to go in a car, then do away with the disco trans & as the 3.5 is still the faithfull old v8, you can pick up the sd1 transmissions or adaptor plates/bell housings to fit other tansmossions

the 5 speed manual is basically an sd1 box with a transfer case on the back so needs a tail housing/shaft change. the 4 speed auto is a zf again with a transfer case. apparently the rover bellhousing and convertor bolt up to a jag (rear drive) zf box so ok there too.

Thanks, that is really useful. I was thinking about just using the engine and box so if you can swap some bits to make it a normal 2wd 5 speed, that could be a way forward.

Is it not the LT77 box thats a standard sd1 5 speed that will bolt straight onto the rover v8? Had one in my zephyr behind a 3.5. You can go the route of using a tvr bell-housing and using a sierra borg warner T5 gearbox, but as i found out, this works out to be a more expensive option!

The RR bell housing is a lot deeper and the flywheels are a lot heavier (low revving mud plugging torque) and I believe that you can unbolt the transfer box and get a yoke thingy that will allow you to bolt up to it (plus they have a 10 1.2" clutch). R380 boxes were also used. If your gonn go down this route it'll probably be cheaper to get an SD1 or sherpa box if you wanna 5 speed. If not worried about cruising speeds get a P6 4 speed, better acceleration........

for some reason the 3 speed in the range rover isn't a very good box, the 4 speed is much better. I am the guy who's thread is the f100 onto range rover, this was achieved using an LSE classic range rover, they are 8inch longer than a normal range rover, also comes with air suspension and this one came with the much stronger 4.2 v8 engine.
