Intake sound weber vs su + ignition questions

Hi guys

New to the forum however I already did alot of research over here for the last few months.
I'm in the process of building a rover 3.5 high compression engine and now I'm at the point to make the decions on what carb I would be fitting and ignition.
The engine will be running in a Range Rover from 84 which will do some mild offroading when it is ready -> no hardcore stuff.
As everyone I'm after the best possible performance sow my 3.5 has already got gasflowed heads and Kent H180 cam.
But for the carbs I'm really looking for the best sounding and performance comes second sow I limited the choices to Weber 500 and twin Su's. Which one of the two makes the best sound?
As for ignition I'm looking for the best reliability and performance but I really don't know anything about this even though I already did alot of research. There are just to many options... Please advise me as good as possible.
Many many many thanks for the help and free information!!! :d

Regards

JK

Personally, I'd not spend silly money on anything which still uses a dizzy.

and why sound?
I would rather have the performance than best sound

If you are going to off road it I would go for SU's unless you like the sound of a flooded carb. 4 barrels like to be flat (and stationary if they get the option) that is why they make wedged spacers for them that correct for 15 degrees of rake of the engine in many installations. Consider the delicate sound of your engine dying as the carb floods when you are raked over at a 30 degree angle in some ditch, an SU will take that all day and not miss a beat, running engines sound much better to me.
oh and a trigger wheel and megajolt for the sparks and dump that revolting distributor and go Fiesta/Mondao coil packs
best regards

Weber 500 no good for offroading.

Reliability. Clever 'lectrics & muddy water do not mix well.

If you are off roading and have proper air filtration fitted you should not be able to hear any induction noise anyway !!

If you want a good noise then cut the exhaust pipes off :)

Marigolds for mutants would work better than tesco bags wouldn't they? ;)

Well, the plugs are no higher than any of those 'clever' electrics. Assuming you position the ECU for wading - not a difficult job.

But how comes then that you see that many people with a weber 500 on theire truck for offroading?
Doesn't the off road jetkit solve the problems you guys mentioned above?

If you ditch the dizzy what do you do then with the hole in the engine where the dizzy used to be? :oops:
Are there any megajolt specialists in Belgium who can help me out or advise?

And if you want to go mental...
What about these?:http://www.v8tuner.co.uk/product.php?id=894 :shock:
Will those work well in offroad conditions?
