I currently have a 3.5 with engine number 22D suffix B in my 5 speed 1988 Range Rover with a V-belt. The 3.5 did a head gasket a while back, it overheated and has not ran well since (I did replace the head gaskets). I have got hold of a 3.9 with engine number 38D suffix C, it has no front cover, harmonic balancer or flywheel only the camshaft, timing gears, pistons, rocker gear etc. I am going to attempt the swap over Easter. Have put bearings, rings, reconditioned heads and a new standard camshaft into the 3.9 and will also use a V-belt. What I cannot find information on is if the crank nose length of these two engines is the same, otherwise I don't think I will have any other issues. Will use the front cover, harmonic balancer and flywheel from the 3.5. Does anyone know the year the 3.9 would be or if its a Range Rover or Discovery engine? And if it is possible to swap these parts from the 3.5 to 3.9? I think the other option I may have is to put the 3.5 crank into the 3.9 then I know it will work.

Different front cover, etc - try and find a complete 3.9 if you're doing this, or if the short engine you have is a known good engine, you should be able to pick up a buggered one for the rest of the parts for basically nothing. Why do you want to keep the V belts? The serpentine system on the 3.9 is heaps better.

You want a disco 1 as a parts car. Move the whole lot across. You gain an Lt230, R380 and hotwire 3.9 v8. A much nicer setup

I think I will pull out the 3.5 and see if the parts bolt up to the 3.9. If not then will look at getting a donor engine/car. The 14CU is not a problem for me as I run it on LPG through a BLOS mixer (surprisingly I am using around 16 liters of LPG per 100km).
