Vehicle also has a 8000Lb winch, front and rear diff locks and a set of mud tyres. Mostly gets driven in the Wombat State Forest. Goes really well except for the fuel economy of around 25 litres per 100km. Currently has 3 gas tanks which can hold around 130 litres.

Good one. Range Rovers always needed a few more cubic inches. Why Rover made the BOP V8 at 3.5 litres in a two ton car is beyond belief. Buick had that engine family out to 5 litres.

My old holden 336 stroker rangie did 26L/100, on petrol! Consider yourself lucky

At the least they should have fitted the 4.4 Terrier motor.

That would be about the same economy as my 3.9 with a manual gearbox running on gas ........... (short trip around town.... much, much worse towing)

Which was made in Australia and the poms attitude was always that the colonials had strange ideas that should be ignored. The good old "not invented here" syndrome.

I have seen a number of engine swaps into earlier RR's including small block Chev, Ford, Chrysler V8's, A Falcon 4.0 litre in-line 6, a Chrysler 265 Hemi 6, diesels various. Yes, those in-line 6's fitted nicely. The SBC Chev I drove was overkill. A very high performance engine of 400+ horses. A high speed rocket ship but very bad mannered at city speeds. I reckon it would have been a pain to live with unless you were using it almost always on highway. The nicest one to drive was the Hemi 6 which was slightly tickled up to around 300 horses but still had low speed manners. Quite quick. The Falcon 6 was a rough home conversion and was a bit worn and smoky. I really don't know why they bothered.

How did the Falcon 6 fit? Were there any issues with the length? Assuming a cross flow motor? Would think that would be a fairly decent conversion with a donk in good nick.

It was cross flow SOHC carb. engine. Both it and the Hemi 6 fitted nicely. I didn't look to see if the radiator had been moved forward. The Hemi fan and fan hub extension was removed and an electric fan fitted. I don't like Falcon 6's. My opinion is that the Hemi was the best 6 cylinder engine produced in Australia, compact, light weight, enormous ports and valves give them lots of tuning potential.

I would love to put a "real" V8 in my disco.

Just need a descent disco to put it in.
A decent new motor.
A shed to do it properly.
The money to buy all the bits and bobs.
The patients to bother doing it.
A wife that will tolerate me doing it.
Kids that will stop annoying me to do it.

Then im good to go. LS in the disco hahahaha.

Na i kid i kid, its far worse than that actually!!!!!

But i enjoy you guys stories and like to wish.
