Mine is Elelbrock intake, carbs & linkage. They designed and sell as a unit. Over 7,000 mile including 4-5 trips to Bowling Green for cruise-in's without 1 problem starting or driving with Cruise-control or A/C on.

Car has never stumbles and when I checked the plugs @ about 5000 mile they all look good and same color. Also original "POINTS" distributor tuned by "LARS". Still running points & plugs I install when I installed the engine.
Again as I stated above these were added for looks -- way to much for stock heads/cams/etc but perfect for looks.
If you are looking for "GO FAST" then look at single 4 bbl Barry Grant Demon Carb 750cfm on top of a BBC like in my '31 Ford
BTW...They also look GOOOOOD

Only thing I change was the fuel line(s)

This is why I love this site other than the nah sayers and they have there own problems. I love tinkering with my cars I built them so why not tinker. I have never done a dual quad set up so this is why I asked a simple question. Sticking with the dual's cause it will look better for a 1980, I am planning on going to 3 2's in the 59 because that will look better in that car. Thanks for all the great advise and when I go to Jefferson in April I will be looking for some new toys for the rides. Thanks again and God Bless all.
They look way cool, aggressive and dominating.
Back in the day they were good for some performance gains, but over time it was discovered that a single 4 barrel can perform better.
IMHO that doesn't diminish their cool factor or performance factor on our old school cars one tiny little bit.
I have not used a dual quad setup in quite some time, but I'm seriously considering it for my 454.
I've heard nothing but good reports on the Edelbrock setup. My only concern would be the 500 cfm carbs. Like Lars mentioned, you run the risk of running a little lean if not set up right.
You could try the Holley setup which uses dual 450 cfm carbs. I believe this may be more of a performance setup if you have the hood clearance.

Dual quads are definitely the Bomb.

I am a bit surprised to hear you say giving up some performance for looks is worth it to you as no nonsense as you were in that qjet on a performer thread, next you will say you are gonna run dual qjets on the dual intake,
is the intake you posted open / shared plenum where it can be ran progressive? I cant tell for sure in the pictures. looks tunnel ram-ish.
Back to the other intake, I called Edelbrock about
http://www.jegs.com/i/Edelbrock/350/54254K/10002/-1
According to the tech they recommend this to be ran progressive it has a plenum designed for that, and while he said that one carb would perform better he also said the dual was good for a couple extra hp, so I had to wonder which is really better,
He then went on to say the big draw for the dual 4 is basically looks not performance and does take some setting up the carbs to really work correctly.
My confusion before was with tunnel ram type 2 4 intakes that can not be ran progressive.

not likely
But that Holley setup shown is the lowest tunnel ram setup. Another kit has a tall setup.
They might could be put on another manifold set up to run progressive. Those carbs are fairly inexpensive and a little lower cfm.
I only mentioned those because of the lower cfm.
I do have a buddy with the Edelbrock system on his 78 c3 and they work wonderfully. progressive, easy to set up and look great with the shiny finish.
Heck, if one Holley is great, Two MUST be superlative!!!!

The Dual four set-up is just beautiful. I had the factory set-up on my 56 Corvette, back in 62, I didn't have many people out run me either, only the fuel-injection cars. There was a 39 chevy that had a Arm with a string wrapped around it, & a hypo needle stuck into the arm,, with a note under the drawing, Fuel Injected!! Another 55 chevy with dual fours, called (The Rattler) was no one to bet on either. Give me those days back. No B. S. from the EPA either! Let me see some more dual or 3/2 set-ups on these cars. Have a great one. Gene
