if you go onto the Edelbrock website and look at the tech installation vids the first thing the chap says is - 'do not over-carb your engine'.
So a 500 is good for up to 305 CI(5 litres) a 600 up to 427 (7 litres) etc.
over-carbing just wastes fuel - obviously it is slightly different for high-rev racers and dragsters.
we find the 500 is superb on all RV8's up to and including 5 litres - the off-road kit is also available for a few quid.
507 pounds from roadcraft uk (official Edelbrock importer) with the manifold is something of a bargain and they come ready to go out of the box with only idle speed and mixture adjustment needed.
The best thing is that for most of the time they run on two barrels, the other pair only opening at 3/4 throttle so they are surprisingly economical.
Best thing is - they stay in tune - once you have it right you just forget it.

Tells me how to tune it, so I'm gonna reset it to zero like how it would have come in a box, back it off 1.5 turns then tune from there

In response to the OP, you have got a few choices here; stick with your SUs (reliable, cheap to service, you know they work over a range of situations), stick on a Weber (don't know much about them) or stick on a Holley 390cfm or whatever (no idea on these on a Rover V8 but you've had good advice above!). Its boring and yes they don't look very good
but the SUs will work great after a rebuild and they of course suit the engine. I just can't see a Holley giving you much, if any more power than a nice pair of SUs? But it will look cool for sure and that's half the battle eh TBH, i dont care about it looking coolIn response to the OP, you have got a few choices here; stick with your SUs (reliable, cheap to service, you know they work over a range of situations), stick on a Weber (don't know much about them) or stick on a Holley 390cfm or whatever (no idea on these on a Rover V8 but you've had good advice above!).

, just trying to see if overtime the tech that has moved on could make a real difference to the running and power of the car, i don't mind throwing some ££, as i enjoy my landy, but it needs to have a real world benefit.
TBH, i dont care about it looking cool
then going efi would be the solution here...

TBH, all carbs are old hat now, as are distributors with their moving parts. Others know more than me, but a hot camshaft is a reasonably reliable way of getting more poke out of an RV8. I'd look at that, coupled with a free flowing exhaust system, then maybe look at at a carb upgrade to build on it, if your after more power.
1500? YOU BE LUCKY..they go for more than that in the states...atleast for a later one..and forget all the electronics needed..
there are alot of varients on the ls range too..seen them here for 800, but you need to get ecu,loom etc on top...
whar exactly are you after doing?what vehiche? what power? are you gonna do it?BUDGET???

I am looking at getting a bit more power mine is a 85 v8, amazing condition 12k on the clock!!! Its been looked after really well, but the 100ish bhp does not really cut it these days
Make them breath better both intake and exhaust, each can be worth 10-12 hp each approx
cheap option then..
retro fit efi system..circa £100 ebay..thats then good for about 165...got any money left then £200 buys you pair of 4 branch manifolds from real steel..that gives about another 10 and will rev better..
then a diffeenyt cam with new lifters at £200..for another 20hp..
oh forgot will need hp fuel pumo=p for efi..add £40ish for efi tank and pump

Yes - and what a lovely thing it was - in a RR 3.5 flapper injection which was giving 12 mpg and all sorts of rough running and starting issues - we put the Edelbrock on there - instant response, smoothness and 16-18MPG if you drive sensibly.
Some people are carb fans and some injection. I prefer the simplicity of carbs and the Edelbrock is the best - Even my old luddite mate Derek Allfrey has come round to this point of view and he has been doing landie V8's since 1975.
My advice, if your engine is sound and you have a reasonable budget would be to:
fit some Hedman 4-branch manifolds(£200),
Install Edelbrock 500 and manifold(£530 with air cleaner)
Install Viper Hurricane camshaft (£275 quid with new lifters and timing gear).
You will also need a new top-end gasket set - about 60 quid, and some new 20/50 mineral oil and a filter.
Derek's boys would do this in a day so you you would be looking about 400 pounds in labour charges.
All in all about 1500 quid.
This set-up would give you about 150 bhp and well over 200 ft/lbs of torque.

And there you have it... 1500 quid spent on an engine and still only 150bhp and less than 300Nm fook sake, there's 300tdi engines making better power than that even if they don't sound as good!
As Dr. Evil says, If you want decent power for your money, go for an LS engine or else a more modern jap or German V8 like a 1uzfe, M60b40 or S62b50.
Or at least go efi and maybe a supercharger
