currently have a 3.5 V8 running SU carbs, any folks upgraded to the holier quads? Was told they should make a fair bit of difference..

Ive herd they are only good for balls out driving (drag racing} etc
I have been known to be wrong though

That could well be the case the guy mentioned it in the context of Rover V8 racing saying the first thing they did was swap the carbs and put a straight through exhaust on..

Are you talking quad SUs or a quad barrel carb
The revue of Quad SU cards I read was years ago when I was in the V8 Manta club
Im sure the conclusion was they are only good for raceing

If the 4 barrel is sized to the engine they are good. Thing is some think bigger is better and there is the problem.

TBH, I was just looking for a bit more oomph , more than happy with the sound track etc

Doc ..why you on defense so often???its too big..its for balls out power..now just cos its fitted to your engine dont mean its tuned for it..
this time i must agree with thor..
if you bought a 3.5 with a holley 600 on it would you expect that to be perfect cos po fitted it??
anyway something to think about and prehaps..(just prehaps) do some googling on..we could both (thor and i) be wrong..

I'm always on the defence with him
its just how it works nowI have no idea where its come from, my mate bought it with the carb on the engine and it ran sweet
I cant find anything relating to the numbers on it but once tuned up properly it'll be ok, its right on the limit for a 429 as far as I can tell from looking online as this is the size of as up to 420 a 750 carb is bang on so if I tune it to be right on the low end of fuel delivery it should be fine
