I am going to buy a new carborator and I was wondering what is the preferred carb on a built 440. I have an Eddy on my 383 car which runs well, but I see a lot of Hol
ley's on built motors. My 440 has a healthy cam and roller rockers. I dont know the details on the cam or motor, but it sounds stout.
 
I prefer the Holley option.
To me, they are much easier to work on / modify. Also the Eddy carbs only go up to 800cfm......
 
Holley. Or one of the 'clones'. Easy to swap jets (no metering rods), dead simple. E-gadle-Brock just never seem to have the throttle response. Though some swear by them, I still haven't heard why.... As for me, Holley makes horsepower.
 
bigger ain't always better in the carb department....I have heard a lot of engines run way better when they take the over-carbed carbs off and put on a 650 or 700.....

carb size depends on your engine build and max RPM's you will see with engine on a regular basis

my vote is for the Eddy style carb

But bigger is better when you do need it!..... Like my engine combo.... :)
 
For a good street driver I really like the Eddy but for a street strip ride go with a holley or clone. Any carb should be tuned for the motor and vehicle it's in. Most people have had some dislike for a carb but most likely the carb was not well tuned.

========================================================================================================= I like the Eddy also. You can change anything without even removing it from the engine. The metering rods take only seconds to change. You can make myriads of changes easily. I could replace everything in both my dual-quad Eddy's and have it running in about 50 minutes at the track.

I'd swap metering rods any day over swapping #*%! jets in a Holley. If you're not getting throttle response from an AFB/AVS, you're not doing it right.

That said, (in gun speak) Holley's are like Glocks, a lot of little things you can add/modify after the sale to tune to the nth degree, whereas an Edelbrock is like a Sig, dead nuts reliable out of the box, but not a lot of 'personalization'.

Ultimately, the best carb is the one you know how to work w/.

Oh, and if the extent of mods are rockers and cam, i.e. no heads...a 750-800 will be fine.
 
I'd go with the Holley but also love Demons and have heard nothing but good things about Quick Fuel. I wouldn't put an Eddie on my riding mower haha, sorry I just don't like them at all. I'll admit they are easier to work on but in my opinion don't come even close to a Holley, just go to a strip and start popping hoods "I'd bet you'd be hard pressed to find an Eddie" lack of adjustment isn't always good. Just my 2 cents
 
I've always thought Holley carbs looked better, but my Carters gave me as good or better power and response, and better mpg. every time.
 
For track, Holley... for street, Eddy. I've used Eddys on my own personal cars for some years now. I'm getting lazier as I get older.

Totally agree. It's all about personal preference, but I prefer Carter/Eddy on the street from a reliability standpoint. At the track it's Holley or a Holley clone hands down.
 
I say try both, and the best one is whichever your engine likes the best. The Holley's seem to be a bit more forgiving in low vacuum situations (i.e. high overlap cams). But for a street driver the AFB design is really nice and trouble free. Holley's have potential accelerator pump diaphragm leaks and the needle and seat o-ring on the center pivot bowl can fail causing flooding. These problems seem to be much more prominent if the car is not driven regularly.
 
If a person has to mess/replace or adjust on a Holley all the time its time to get ahold of someone who knows how to set one up right in the first place.
Also if you can't run a Holley on the street everyday, again get ahold of someone because you need help.
My last 3 cars have had those junk Edelbrocks on them and I replaced them with a Holley or various CFMs and its like night and day on how much better the car runs.
If you can't sit a 750 CFM Holley on just about anything, adjust the floats, air mixure screws, idle and be driving there is something wrong somewhere else.
