Alright guys at the moment I have a warm 202 thats running a 350 holley.....
Question being, would a twin stromberg setup be more responsive?
I had a fuel injected black motor on the go but since fallen through so am looking at different carb setups........I am keen on triples but want something a lil different.
Ideas and opinions.........

350 holley/twin strom setups
I don't like Holleys, never have.Love Weber carbs for performance applications 
.
However, I reckon the Holly would be better than the twin/tripple carbs if get up and go is what you want.Assuming you mean twin/tripple downdraught strombergs??
If we are talking twin/tripple SU's then the Holley may not fare as well.
For nostalgic reasons you can't go past twins or tripple strombergs I think but may not go quite as well as a single holley.
The only way to really test the performance evaluation is to dyno test output with the Holley as is and then try the twin/tripple setup on the same motor as is if you really want to try it that way.
Dyno figures don't lie.
350 Holleys have been used as the red motor recommended carb replacement for years.
I'm into "period" type modifications so I'd be going for twins/tripples if it was my car.
Replacement carb selection are one of the biggest arguementative points people have when it comes to engine mods.
Some may agree with what I've said and some may disagree, it happens.
Just my thoughts,
Terry.

I can't think what to write here so this will do.
Nup, all good advice Terry.
But I'll throw another option in the ring, Carter/rochester/edelbrock 4 barrel carb (465/500cfm). If you have a motor healthy enough these are a good choice. Small primaries for some form of economy and drivability then a big dump of fuel when called upon. Setup right a 4 barrel is a better option than multi carbs for some one not keen on regular tuning and who drives every day.

Speed and Style........... One day I'll get the speed bit.
The best carb I had on a 6 (265 hemi) was a 650 double pump Holley, it was ultra responsive, it was a very well worked motor though.
Castlemaine rod shop recommend the 2 barrel stromburg (186s carb) over a Holley on there super charged Holden 6, it has better responsivness and more economical than the Holley, Trev .

Yep, the 450 is called a 450 Economiser and was produced for engines up to around the 350 cube for its namesake "economy".
I had one on a mild 253 in a UC Torana years ago and it went well ( even though I don't like Holleys ) and from memory it was a vacuum secondary with a squarebore base.
I've got a feeling the 450 was a different design to the 465 as the 465 was a more performance oriented carb but can't remember exactly as I haven't played with them for years.

Don't know if they are still around or not but there was a company called "Hume Performance" that could supply and rebuild all types of Holleys so if you decide to go from 350 Holley to a 4 barrel Holley ,look up their number on Yellow Pages online and I'm sure they would advise as to what Holley would be best to use.
Just remember, bigger isn't always better, depends on engine mods as to what's best carb to use.A lot of engines are overcarbed and actually can run better on smaller CFM carbies than the bigger CFM ones.
They did have an ad in a 2006 Street Machine mag I found at work the other day so I'd guess they are still around??
