Hi all...
My question may at first seem easy but i want to put a dual quad set up on my 70 coupe 350 and need to know if it will fit. Has anyone done it? I have searched for pictures or articles without any results. I know hood clerance is at a premium and i am willing to put a big block hood on if it will work, however i won't go for the L-88 hood.. Any one done it? any pictures of it done??? Any imput on this would be great!!

CAN IT BE DONE??????
man, this is my thread, hahaha, anytime someone sees my engine they ask WHY?? i say why not. When i was a kid my dad rodded a lot of cars, and i have a lot of nostalgia for dual quads, tri power, ect, its pretty.
check it, sitting in my 1980





edelbrock C26 intake, they make it in a low rise.

the intake has the old style oil fill tube, which allows you to use solid valve covers, which in my opinion look way better, you will get people who tell you that you need PCV, this is not true, all you need is the breather cap on the vent tube. Engines ran for years without pcv



also if you are running dual quads, a word of warning, you will need a custom throttle cable, as the stock one will be too long, and you will need a custom transmission kick down cable, as that will be too short. Dont sweat any speed shop will be able to whip you up some custom ones, cheep. Ok well if you can afford dual quads, then that will be the cheapest part of the process. the C26 intake is designed to work with a pair of edelbrock carbs they sell for the C-26, (one ele choke, one manual choke) they come "pre tuned" for a 350 sbc, that just means that it should run when you first hook it up, you will still need to romance them a lot to get it cherry, good luck, i say its worth the work, cheers

I certainly hope so, wasnt there a 1st gen (small block) Vette that came factory with dual quads? 1958 corvette had two different 283's with dual quads....carters I think

Dual quads were used from 1956 to 1962 on vettes. Here is a real nice setup for a vette that is for sale here on the forum.

Are you running the set up under a stock hood?
I'm not sure if my 70 has less clerance then your 80....
cool set up!!!

so i keep reading that the vast majority of people overcarb their engines.
i thought it means using a 750 cfm when you really need a 600.

now i know what it really means.

I have the Edelbrock polished aluminum intake with 2 Edelbrock quads, PCV and a shielded breather.

Steve is right about the throttle cable being too long. Steve, where did you get the custom cable made. I need a shorter cable for my '73 SB auto.

I'm not sure dual quads makes sense on a SB but I like the way it looks.

Actually with 2, 3, 4, or 6 carbs the CFM of each carb has to go up. Less vacunm signal. The small base tripowers have 3-278 CFM carbs. Equivilent to a 600 CFM 4 bbl. My large base Tripower has 3-378 CFM carbs. Equivilent to 812 CFM 4 bbl. 2-500 CFM 4 bbls is not the same as a 1000 CFM 4 bbl. Probablt closer to 750 in function. Properly tuned and jetted they function well and my small block tripower setup gets way better mileage than my 4 bbl ever did.

No offfense intended, but are you the HP police? Are you the one to determine if he should buy it or not? You kinda remiind me of thte Ford deaership in Tuson. They asked me why I wanted a F350 diesel truck, what are you going to pull?

I mean, really, who cares, his money, time and work to do it.

Oh, by the way, Lokar makes some nice throttle cables, and some nice trans kickdowns. I've used both on my 69

You are 100% right... my hard earned money!!
Those who can.... do
Those who critasize.... live at home and drive a pinto!!!

Go for it and ignore the naysayers , properly sized quads will give great performance and mileage [ if you behave] .

GM put dual quads on anything you wanted starting in 1956 Chevys Rated then 225 HP 265 ci. engines. Very popular on hardtops and convertibles. There were also two different HP engines sporting quads. Those with solid lifters and those with hydraulic cams as did the FI engines up through 1961.....

Functional and looked good, you will enjoy......

Gilbert chevrolet sells a dual quad crate engine. Puts out some pretty good dyno numbers. More info here.

Gilbert Chevrolet
The Gilbert Chevrolet ZZ4 (350ci) Nostalgia Deluxe engine (428 hp @ 5,600 rpm, and 448 lb-ft of torque @ 4,600 rpm) is based on the GM Performance Parts ZZ4 crate engine. The company took the GMPP ZZ4, added a more aggressive hydraulic roller cam, 1.6:1 roller rockers, modified Edelbrock classic valve covers, and topped it off with the new Edelbrock Performer RPM Air-Gap Dual-Quad intake system. The induction system is topped off with dual chrome air cleaners to enhance the vintage looks. The ZZ4 engine features a forged steel crankshaft, forged powder-metal rods, and hypereutectic pistons.

its when you stop behaving that you get in trouble

The only reason I mentioned it is that I would hate to see someone ruin a motor by "Washing" the cylinders with fuel if they were not set up properly.
I have been sick and unable to follow my posts but I think this was>..................


Uncalled for............Only for the Pinto part

Oh never mind!!

Have fun............That is why we own these cars.
And as a matter of fact I will probely have dual quads on my BBC when it's done also!

Does anyone have the proper specs for the dual quad carbs.......................... what does edelbrock recommend for jets and needles in the dual 500 cfm set-up ???

Or............. has anyone come up with a better combination for this set-up ?

Inquiring minds want to know.........................

I have a Edelbrock set-up for a BBC and I could get the rod and jet combos but,.........................I left it in my Pinto!

Little Mouse

Edelbrock 500 AVS carbs, EDL-1803, EDL-1804 calibrated for the dual quad setup, EDL-18034, EDL-18044 same carbs in EnduraShine, If you want a calabration kit to further tune EDL-1486.

Thanx, LM........................... I've got a couple of EDL-1804's that I want to make sure the jets and needles match up before I crank her up !!! Rick
