I find it's easier to get races when I show them my "Edelbrock 600 racing carb". It's backed up with a system that uses a ported small body nitrous solenoid as the jet, doesn't seem to matter much that the carb is "too small"

It's simple, if you want the engine to run better and run quicker, get a Holley.
Most Holley's will be closer in tune on any given combo.

Totally disagree with the title. I've owned both. Still own both. I do not see any more simplicity with a eddy vs a Holley. Try changing a needle and seat and adjust a float level on a eddy as fast as the 1 minute that I did in this video on a Holley.

A jet change, power valve change, accelerator cam change, the list goes on. lol
It only took me a half a life time to figure it out. I ran Carters for many years, too many. lol
- I can change JETS faster in a Holley than anyone can in a Eddy. Eddy owners have "minimum" control of jetting with the metering rods/springs, but must remove the top of the carb to change the JETS. And, the jetting on a Holley is much easier to understand than a eddy. Talk about science, on a eddy you have to add/subtract the metering rod into the jet size..... LOL
- All the other "tuning" you mentioned for the Holley is for precise tuning. Not that the eddy don't NEED it, it just don't offer it... LOL

Price difference in tuning kits and individual tuning parts.
science...well..
..They're just baselines is all

Honestly...…. with all your threads about heads and yaddy yaddy yadda... It would be cheaper for you to buy a good set of Holley's and put them on your car than to mess with buying and installing heads. (Why do I even bother offering you suggestions...
.. LOL)

I like my Edelbrock AVS2. Yes I had to study the tech to figure it out but the wideband made it easy. Since I started my car with Holley I thought that was the way to go but I just could not get it to a point that I was happy with it. Work on a Holley and get gas all over your motor. Tune an Edelbrock and remove the air cleaner and play with the rods and springs. I do think this thread will go the way of "how long is a piece of string". It's a matter of personal preference. That said my next build will be fuel injected.
Worked on Holleys for years on the street. I will not have one, except to sell. Always working on it, never quite right. Any 4 other barrel is better for the street. My brother had a Holley on his 65 Mustang 289 K motor that was messing up, so I put a MOPAR Carter AVS on it while I rebuilt the Holley. When I was done rebuilding the Holley, he told me to sell the Holley, because he was keeping the AVS. It ran so much better. Sold all my Holley "tuning" parts years ago, now I never have to "dork" with a Holley again. A friend of mine Just pulled all the Holleys from his street cars and replaced them with Edelbrocks after his twin brother had a beautiful 55 Chevy Restomod catch on fire from the Holley. Carters just flat out work.
For informational purposes, to change the fuel mixture with a Carter/Edelbrock, you just change rods. I does not get any better, faster or easier than that.

I totally diagree with the title.
For the same reason as 318willrun. That is, working on them, in some ways Holley is simpler.
For the opposite reason as well. The science in them is the same. Carter just applied some of the science differently than in some Holley carbs.
There is no question here.
Not sure what you're looking for:
or
But if looking for a true match up,
you need to lay out what the arguement/discussion is actually about.

I've been running an early1970s 750DP since about year 2000. After the initial tune, I've just been driving and driving and driving, to the tune of over 100,000 miles. Carb is sorta worn out by now........ but it's like the Energizer Bunny.
On other combos , I have had TQs and AVSs and AFBs, and after the tune went in, I got no favorites. Well except for the TQ moan.......... I love that,lol.
Run whatcha got.
If yur buying used, take what comes .
If yur buying new; flip a coin.
If you got the coin, maybe get a Goggle Valve and write a review on it. I'm kindof eyeing that thing.

The Carter/Edelbrock carbs are simple and usually spot on OOTB for many street applications.
On the other hand they are totally useless in circle track applications. Not enough fuel capacity, not enough adjustability... just wrong for the job.
For the street I'll take a Carter/Edelbrock. Had my blown Hemi set-up to use a Carter. For my dirt car I have a an ancient 750 set-up for alky.... my son has the same on his dirt car but runs gasoline. I really would like to try an 850... gotta find a good deal on a used one. A good, new Holley style is ubually over $1K... too rich for me.

That is why he made a title and got his popcorn. He wants folks to fight about it. He is bored and looking for free entertainment.... LOL
Correct! After the initial tune, they just keep going and going.... LOL. ... LOL.

The problem with the Carter is simple. Float bowls way too small. Not enough needle and seat area. The float bowls sit over the hottest part of the intake.
Ability to tune individual circuits on the Carter is much more difficult. Not that it can't be done. It's just much more time consuming.
The Holley is relatively simple. The real problem is that for more decades than I care to admit, the idiots at Holley and the neophytes who write trash articles teach people incorrect tuning for the Holley. The biggest mistake guys make is not getting the power valve timed correctly. That's HUGE for a street driven car. And Holley is evidently too stupid to teach its users how the main jet and the power valve work together and how to tune for cruise and WOT using both. That has done more damage to Holley tune ups than anything else.
The science of both carbs is the same. A correctly tuned Holley will out power, out drive and out MPG a Carter all day long.
In fact, it's a well known fact that both carbs are 100 MPG carbs.

Ditto, a TQ or AVS please.
Ehhhh, not really every time..... Sometimes they have been beyond pig rich for me. Combo dependent! Nothing more, nothing less.
The Holley has the ability to be “Precision Tuned” Oliver an Edelbrock carb with so many internal & external adjustment points, an expert should be able to get them to run like fuel injection.
Disagree there!
Agree there!
I’d like to add that a Holley can be confusing to new guys to the carb with so many adjustments available to the carb in and out. This is Daunting! As well as confusing. Once you understand, yes, simple. Not everybody has the will, want or brain power.
The Carter is simple. The amount of adjustment to it is limited. Making it difficult to dial in like fuel injection. The secondary on the 750 AFB needs to be modified for a serious engine. (Ridiculous!!!)
The Carter or the slightly updated Edelbrock version (and I mean slightly!) is just a stock carb that can handle only so much as is. Modifications to only so far and still pale to a basic Holley. But they can run!
I think the biggest problem with people advising a Holleyfor use is just saying, “Get a Holley” without saying which one and why and lord help us anything I gotta information or further parts to get that are needed or maybe of use & helpful. There are to many Holley’s offered to just make the blanket statement of “Go get one.”
Comparing the two carbs isn’t a fair game with the available upper level Holley. It’s a slaughter on the Carter. A more just and fair compression is a base 1850 or 3310 vs an AFB or AVS since all of the above were at one point a OEM carb.
I ain't no boy racer, I just want it to start and to tooldown the road, chillin! NO changing this and that's, no power valves, no double pumping nothing. Let the fast guys go the track and be fast. Fly by my ***!
Mopar loves Carter. hahahhhaa
Mopar loves Carter. hahahhhaa
LMAO! Well, once again, the nail was hit on the head, the right part for the right application. My Carters/Edelbrock’s have been flawless on my street bound vehicles as well as my street bound Holley’s. (1850, 3310 & 6 pack carbs.)

Well I posted that and went to work and just got home LOL it seems as 20 responses so far. Time to go back and read and see what happened....
- I have a 750 Holley Double Pumper that works awesome on a stock 360 with stock converter and 2.76's. Nail it from a dead idle and no coughing, no fluttering, no hesitation, performs great, cruises great and drives around town like a dream.
- I have a 600 eddy on my wife's 360 Ramcharger and it runs super as well.

On a Edelbrock I've always check the float levels but they've always been perfect on everyone ever touched. Guess I just got lucky. Also I've never been in any kind of race to do anything on a carburetor so being able to do it real fast doesn't help me any...
You do realize all your precise tuning is lost as soon as the barometric pressure changes from the time you tuned it and also anytime you go to a different elevation?
If your suggestions are going to be spend $2, 000 on two thousand-dollar Hollies then yes please keep your suggestions, smart move..Honestly...…. with all your threads about heads and yaddy yaddy yadda... It would be cheaper for you to buy a good set of Holley's and put them on your car than to mess with buying and installing heads. (Why do I even bother offering you suggestions...
No duh....
Agreed.
LOL I look who cometh forward with the most comments LOL... FISH ON!!
I believe there is a tenth to be had with a switch to a pair of Holley's for j pars combo.
A pair of box stock Holley 600's would do it.
