Finalising my 489 build and always wanted to run the edelbrock dual quads as a nostalgic look to the BB.. Builder doesn't like and this seems to be the norm with most builders. Go Victor Jnr and 950cfm carb. I have it already and will lose plenty money if i try sell. Why don't most builders like edelbrock carbs. I'm not out to make 900hp. Just tuff street car with a street roller camshaft.. Dual quads are 2x500cfm which i wanted to run as one. Not progressive... Never had an edelbrock carb so why the hate.Edelbrock been making and selling these carbs for long time so what's the problem. They are the new ..

Edelbrock makes fine products. Great heads,, and intake manifolds. I think a lot of people prefer Holly carbs. Not sure of the reason. Would have to do a,one on one comparison. Does,your,carb have sight Windows?

They are a carter style carb been told.. No sight glass for levels.. From a little bit of research i have done they are adjusted differently to Holleys.Bought the setup mostly for looks but saw a 540 BB making over 720hp with them so figured they not so bad..

I would put it on. It is a neat setup. Its not a performance setup. The car would probably make more power with a single plane, but who cares.

Edelbrock

From what I understand, Vic Edelbrock bought Carter and improved the product. I've got a set of both and the edelbrocks are easier tuned.

If the builder don't like your choice, go get an old a$$ Quadrajunk and tell him to use that. He'll run to the edelbrock.

Looking at it from the builder's side, it's his name you will be saying when the questions are asked about your engine. I think he's trying to keep it easy to set up and maintain.

This is the down side to the industry. It didn't matter if the engine was only painted in our shop. When the pieces went home with the customer and was assembled in a dirt shed with a hammer and chisel and kicked a rod at the track, it instantly became our engine!!!!

I switched from an Edelbrock (actually an old carter AFB) because when my car sat for awhile I had to crank it a long time to get the gas back up to the carb. I don't have that problem with the Holley, the fuel bowls stay filled. I can leave the car in the garage for a month now and have no problem starting it up.

Also I am familiar with Holley tuning more than Edelbrock, after a carb rebuild I still had performance issues and didn't feel like learning how to fix it, plus I already have a big collection of jets and tuning parts for the Holleys. Just made sense for me to keep both cars in the Holley family.

I have a Holley 750 DP on my Nova, and my dad has an Edelbrock 650 on his '74 Monte with a mildly warmed over small block. After doing light tinkering with both for "tuning", it's kind of a mixed bag as to which is "better". The Holley carbs tend to have better fuel metering circuits and perform better flat-out for some reason, whereas the Edelbrocks seem to be better suited for maintained repeat cruising without any headaches. The whole deal with the fuel bowls running dry I have experienced though, kind of annoying when you have to crank your car a bunch after it sits for a week.

I will say this much: I know more people I can call on for Holley parts to tune than Edelbrock/AFB carbs. A handful of my friends have jet kits or spring kits if I need to borrow some; can't say the same for jet rods and the like. If your respective builder has all the parts and tools to tune with a Holley and is more familiar, I would probably trust his opinion. If you're going to do the tuning and you're comfortable spending the time and money on jets/parts, that's on you.

No intentions to race so if a single carb made 30hp more than what i have i would never notice on the street. 685hp as opposed to 710hp at 6500rpm for a split second. If i didn't have it already not a problem but looking at another 2k for single carb... Yes i understand it's got his name on it... Way i look at it i have 2 full jet and needle kits. New. Once its tuned as good as can be don't think i need to play around again really.. I had quad webbers on an old engine and that i truly understand is a pain to setup and get right.Everything we buy down here is generally 60-70% more than USA coz of freight and taxes.

A guy in town had a '64 2 door sedan with a mild small block and dual quads with Edelbrock or Carter carbs. It ran good looked good. He just wanted something different.

One big advantage to a Holley if fuel bowl size. And if stock Holley fuel bowls aren't big enough, you can make them bigger. With an Edelbrock you have what you have. Also Holley's seem to have more ways to meter the fuel more precisely. I used to run Edelbrocks on my street car with cast iron intake and warped 2 main bodies to the point they wouldn't run.

A single 4bbl will outrun that dual quad set up, but if it's just a street car I'd run it. With a 496 and the way Edelbrock carbs work, I think you would of been better off with 2 750cfm carbs. Those 500's might choke it down a bit.

I have put them up for sale. Original engine was a hydraulic roller 454 making 500hp..So set up was intended for that. I have come this far and have always listened to what my bloke has to say. It's what he does 6 days a week.. So either they sell and i get some money back or they will look good on top of the cabinet in the spare room.... Now do you go an Edelbrock Victor or Weiand Track Warrior... Hahahaha.

Out of the 2, I would go with the Edelbrock intake. I ran a super victor on my 540 and 565.

I've got the same 2x4 setup on my small block, and although I've not got much road time on it, I really like it's old school look. I've got it hooked up progressive, and not had one problem with it. I would tell the builder it's what I want, hook it up!

I already own it and it would kill me to see it run fine on another
BB if it sells... I'm going to take a big hit if i sell it.. Would like to try it and see... Have been told that these Sniper and Fi tech EFI kits don't want to run on engines with low vacuum... I went down the path of dual quad Sniper but $3200 down here.. Stay old school with carb or carbs..

I still say if you want it then use it. I don't disagree, its a crappy intake design. A taller plenum intake will ALWAYS outpower a low intake and especially one that they are trying to cram 2 carburetors in a small area. So yes, a tall single plane, even with a spacer will make more power. that is a fact, but if you want the look and have the intake then put it on. I had a ported Super Victor with a 1" spacer and a Dale Cubic 1150 dominator on my 565, and I was told a tunnel ram with 2 carburetors would be worth 25-40 hp. But I ran a 4" cowl hood and didn't want a scoop so I never changed.
