Not a RV8 enthusiast, but I think Rover P5, P6, SD1, Deranged Rover, Disco, TVR(?!)
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

jay! theres one on ebay at the mo, i posted the link in the bargains elsewhere section. obviously a bit of a twat having to get it delivered/collected
from the mainland but still might be worth it. good luck anyway!
ps since im already posting, and to avoid dragging up the other thread, apparently the LT77 and LT85, and maybe the newer r380 box, should all fit to
the T16 engine.

jay, we got our rebuild v8 engine off a guy in the republic of ireland. I think he works on them a fair bit, might have another some time, I could put
you in touch?
and yeah, the engine you want comes out of a rover SD1 aka "new" rover 3500. Ones off older rovers and landrovers have various little
issues that mean they're less desirable. There's lots to learn about the variations 
rover v8s come up on eBay all the time in various states of fuckedness. keep your eyes peeled (that's how we found ours)

If You can get a 3.9--4.x out of a fairly recent rangerover then you will have bags of BHP without much modification. Im using a SD1 3.5 with a webber
500/cam etc and i dont reccon i will get much better than 12-15 mpg. I will leave it to you to work out how far you can go on a tank of fuel but
needless to say it aint far. Its a subject thats well work some leg work and well worth asking questions before you splash the cash
Cheers

They are also in Triumph TR8s, Morgans (yeah like you'll find a scrapped one) and ambulances, police vans older landrovers (in a really low
state of tune, one version only makes 95bhp!) .
The most common seem to be 3.5l SD1 and Range Rover classic motors, the latter being typically of low compression and lower power.
If you can, by all means get hold of a 3.9 or larger but they are much more rare 2nd hand it seems.
Did the Stag ever have the V8 or was it just a 6?
MGs had em too, but again in a low state of tune.
Donners, what makes you think the mpg will be so low? That's what a friend's fooked forward cab landie gets and it's about 3 or 4
times heavier.

The stags all had their own V8, apparently based on 2 dolly sprint engines welded onto one crank

There's a chap on ebay and he always has loads of rover V8 parts for sale. He is in Ballymena. His ebay ID is "rockercover"
This is one of his items. http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=2456498702&category=10414
drop him an email!!??

Julian,
I think if you are only getting 12-15MPG then something is far wrong. My Dad had two SD1's from new (an R reg and a V reg) and both would easily
exceed 25MPG around country roads. On a long trip such as the annual trip to Manchester airport on the way to the family holiday he would get in
excess of 30MPG. This is in a 1400Kg (kerb weight) car fully loaded with 4 people and all their holiday luggage sitting at 80-90MPH on the M6 over 250
miles.
Obviously the Locost ain't great for aerodynamics but cruising around the country it should be able to turn low to mid-twenties MPG at least. Of
course if you are always in 2nd gear with the tail hanging out then mileage may vary... Come to think of it I expect to get around 6 MPG on that
basis!!! 
ps. Julian, don't accept the old excuse that the big fat carb will cause fuel consumption to increase as this is bollocks. The weber 500 is a
great carb and should be economical and responsive when set up correctly.
Also, try to avoid the Range Rover RV8 engine as the compression is really low (8.13:1 usually) and makes it drink fuel and perform relatively poorly
for its size. Of course a 4.6 litre engine will be more powerful than a 3.5litre SD1 engine but the bigger engine would still be less efficient. The
ideal engine to go for is a late Vitesse or Vanden Plas Efi engine from an SD1 (1982 to 1986 I think and with engine number prefix 30A....) as these
have better breathing heads with waisted valve stems. They also have a 9.75:1 compression ratio compared to the normal SD1 ratio of 9.35:1. Expect to
get nearly 200BHP from one of these with a decent air filter and a nice big Weber 500 carb. I'd ditch the fuel injection if I got a Vitesse
engine as it is easier to set up a carb once you start to modify the engine. The efi requires special equipment to tune it up on a rolling road. Also,
you could sell the efi kit to someone and recoup a good chunk of the cash you paid for the engine in the first place.
Cheers,
Craig.

Good point craig. I'm wondering if we could get a couple of hundred for our injection system and get a weber 500 kit instead. I'm not sure
how much it'd sell for though.
If I get this job I'm going for it should be quite affordable!
Maybe a sexy cam with rhodes lifters too...
Must.. resist...

Having read what other Dax V8 owners are getting fuel consumption wise, i stick with my 12-15mpg claims but this is a worst-case scenario. You can as
previously said expect to get from 20-25 mpg on a good motorway run with the variance depending on your final drive ratio and gearbox. A long 5th gear
will help. Around town or when hoofing it, owners have said that the fuel figures go through the floor!
All that said, I agree with what has been previously mentioned with the exception of the low compression engines because these are ideal for turbo
charging, but then you have the problem of two small barbeques under the bonnet cooking your feet.
Here is my engine so far

Looks nice and shiney Julian.
Ours could probably do with a bit of a clean but it generally looks fine:

Looks mighty fine
Whip them covers off and that plenum of and give it a good hard polish. They will buff up a treat.
Have you seen this picture of the Dax with the plenum showing through the bonnet? It looks stunning.
I had a go in that car and i can honestly say that it was the fastest thing i have ever been in! but it did have over 300bhp so god knows what the
fuel figures would be like on that?

Yeah I do really like the V8 Dax demo car. Saw it at Donington too, very nice, it's a 4.8L, so pretty beefy
I'm not sure how it will look in the end. I doubt we'll have a chrome inlet pipe like that, probably just a bendy hose or a 90 degree
silicone hose bend and mount the fillter/airflow meter on the battery shelf, trying to keep the pipe inboard of the chassis.
We could have the plenum sticking up but i'm a bit worried about the vacuum takeoff on the top of the throttle assembly and the cold start
injector being outside the body. I think a bulge would be more sensible and probably more SVA friendly. A scoop may be nice in order to get cold air
to the filter too.
There's an EFI V8 Locost in the back of Ron's book, but it's pretty fugly, the scoop is too big and looks pants.
(Sorry if it belongs to anyone on here!)

Julian,
I'm with Craig on the fuel consumption figs!
I managed 28 mpg in my 3.9 Range Rover going to Brighton an few years back, and that's a mix of v. fast A road/Dual C town.
And I wasn't hanging around!
I only even got 15 mpg when it was using choke (inj)
If I ever get hold of a 3.38 diff, I reckon 35 - 40mpg at cruise!

Hehehe, and twice as unreliable too....
Dont just build it.....make it!

Simon,
My original objectives for my car which I wrote down right at the start said that I hoped for 35MPG but I'd be happy with 25 to 30 I think with
30-35 on long lazy cruises.
Julian,
Turbocharging! Well yes okay an 8.13:1 compression ratio is ideal I agree but come on! You're starting to sound like Hicost!  Simon had enough
trouble fitting his steering linkage into his car, never mind a pair of big turbines!
By the way guys, I am told (not tried it myself yet) that you can swap your rocker covers over to put the oil filler and breathers at the back if that
helps with bonnet clearance. You can also shorten the filler neck and attach a remote breather too if necessary.
Cheers,
Craig.
ps. My engine is way to manky at present to show you any close-ups of it! I'll clean it up next time it's out of the car.
