Look under the hood of just about any Mopar NSS car and you will find the 750's or the 800's. I'm talking cars that can run an index anywhere from a 12.50 et in 1/4 mile to an 8.75 et in the 1/4 mile 
They work fine on my car and I run 9.60's and the most I have done with them is maybe change the jet size and the rods to be used. I also know of a few that have changed to a Holley from the 750 and actually went back to the eddy's. I also run one on my 70 Challenger 440 street car with no issues.

yes that's because you run TWO and you HAVE to use them. If you were able to run two holleys in NSS you would and your times would be better.
I can run 2 Holley's in AFX which is the 9.75 and quicker classes. No need to change them though as the eddy's are doing just fine - like I said even on cars going 8.75 and quicker!! There may be some gain in the Holley's but I don't think it would be significant enough to change an index by .25 et unless you were very close to start with.

Not true, we can run Holleys. They aren't any faster. Guys that use Holley's claim better 60 ft. The difference isn't much .02-.03. In my experience the Eddys out MPH the Holleys. Either way they're very close.

My dislike of all the Carter AFB based carbs is the lazy accelerator pump, way too much throttle travel before you get a healthy
Holley pump shots are more positive.

over the last few years been seeing some negative comments about the eddy 750 carb. whats wrong with them? was thinking of getting one for my fury
The few that I have used were OK. The float level adjustment is really important on those carbs, and the only way to adjust it is by removing the top.
When tuning them, it is really tempting to just throw different rods at it, which is more likely to get the carb out of tune, then changing the jets.

The few 750's I delt with were all lean the way they came. I did some tunning and they worked fine after that. Here is what my brother says about them as he runs 2 of them on his 64 Fury wedge NSS car. He is not crazy about running just one on a car but he loves running two of them on his car.  Ron

My Carter Comp AFB that I had on my 383 would alaways run lean no matter what pump, nozzles, jets or rods, then I adjusted the float level higher than spec so the bowls would have more fuel in them, and it finally went rich. After fixing the float level issue, I ended up back to almost the stock jetting.

I've tuned and had good luck with other Eddys, AVS, TQ, and Holley offerings. The 750 Eddy was trouble on any number of engines. They just don't seem to respond to changes like other carbs. You can get them to run better after some work out of the box, but not a easy as virtually any other carb. Then you might even be lucky enough to get one that has mystery problems with signal. I would rather put a carb that works right on it and be done. No reason to fumble around tuning a carb when you could be driving the car.
I want my fair share

I used to be all about Holley...had a 2bbl 500, a 4bbl 390, an 800...They started stumbling over each other...the 500 and the 390 were in different stages of a Mod Slant 6. I couldn't get the curve correct but an OOTB Eddy 500 took care of it and then some fine tuning down the road. 70 Charger with the 800 Holley, Choke horn milled off, left me stranded one too many time to the point where I had it professionally rebuilt to no avail. I had to get that Charger to a car show...removed the 500 from the slant, bolted it to the 440 and it was NIGHT AND DAY and I was under carb'd. When we were finishing up the 69's restoration, we opted for the 750 Eddy. It ran and performed, always turnkey, never had to tinker with it. The thing most people forget when installing a carb is A/F ratio...Drill your exhaust people, pay the money for the Wideband. You'll save time and money in the long run. the 750 is now on a friends car and it woke up his 58 Plymouth from the Holley that was on there. my 69' 440 has Dual 500s now and running sweet....I can press the pedal so far and go for a nice drive....and if I wanna get stupid I can go sideways with all 8 dumping fuel in  )
