Was wondering what your take on these where. I need two for my long ram and can get a real good deal on two used ones...
I have no problem rebuilding them but was wondering how well they worked...Adjustment and and tuning... This is going on an almost stock motor..
Opinions please.............

Yes they are. I've never had any trouble with any of the Carter or Eddy carbs. The Eddy carb on the Ramcharger is about 20 years old. The one on my van is about 10 years old. The ones on my brother's '71 Sebring are about 2 years old - no trouble with them.

This car did not come with the long ram so I am making up stuff to use... Small cam in a 383 with 10=1 comp and headers...
The two he has are the 600cfm ones...

Well, a 383 is not going to like all that fuel so you'll likely want to jet them down a mile, a better combo would be a pair of 500cfm Edelbrocks (1803's). They are factory calibrated for small engines and mild dual quad applications. You will have all of the same linkage, air cleaner, and fuel line issues to deal with but it seems that in your case (custom) that's less problematic.
^^^Good advise^^^^
I have to say I like Eddie carbs. And I do have to say the electric choke models are more for stock motors are are lean from the factory.
I have had a 1405 with fuel in it since 1984 on a 340 and am still using the same carb today.
Lastly I have to recomend leaded race gas if your gonna store your car for long periods like I did. This 1405 sat in my garage on my 340 in my car from 1986-2003 always with 110 leaded race gas. I started it on the average or every 8-9 months during those 17 years and it always started.
I tune mine all the time because I take my car nowadays all over the country to drive it. Were at 800' in Cincinnati and Reno NV(have family nearby)and places out west are 6000'+, can't leave it like it is like when were in Cincinnati.
And you all mostly know that I've driven it to top of Pikes Peaks at 14000+' twice so far, it's got to be close(jetting) to make it up that monster mountain.
Yup it's been a good carb to me.
One wrong move....

Thanks, I was looking for a good technical answer. Glad you could help.
Doug
The calibration on them is hit or miss, mostly miss .
This isn't the first time this has been stated about this carb, for everyone person that has no problems, 3 do, if you want to go and buy one and use it KNOCK YOURSELF OUT.
The Thunder Series is a better carb, it has an adjustable secondary air door, the performer is not adjustable unless you disassemble the carb and either add weight or remove weight from the butterfly plate.
If you go to the tech archives and look for the thread by fast68plymouth on his 383 build you will see that he compared several intakes and carbs on the dyno and the ebrock version of the 750 just flat out did not work well. He tuned it some, yes he knows how to tune a carb, and it just didn't work well at all. He stuck on a Carter 750 AFB , pretty much the same carb , and it was fine, there is just something not right with the calibration that ebroock has these carbs built with.
Considering there are other choices one would be better served using something else.
was that good enough ?

I love Edelbrock carbs.
IN PAIRS.
Mild engines, two 500s. A little raunchy... two 600s.
Total drivability and good top end power....

I have been in contact with 2 performance shops that build race and street strip motors and both have said the same thing when i gave all my engine/drivetrain specs.....get rid of the 600 cfm eddy and put an 850 QUICK FUEL ,they both explained these carbs are superior in the tuning department and it's all they run on HP dodge motors.
MUSCLE MOTORS/MICHIGAN
PRO-STOCK EDMONTON
For my application (440hp) I was told the 600 eddy is robbing me of 50hp or more.
Coming from these guys I would have to say they know their carbs.
hope this helps
Not questioning the skill of the names you dropped but it doesn't take a rocket scientist to figure out that a 600 cfm carb is too small for that application ... or maybe it does ??

My last build I back to backed Cater 750 comp to Eddy 750. Ran exactly the same. Mine are an older pair , maybe the new ones are different. I've run smaller and "unliked" carbs on many street/strip 11-12 second builds with success. I not saying to buy or not buy. I can tell you I've never had a carb I couldn't make work. Like I've stated before. I run AFBs,Holleys,T-quads. Depends on the application.
Doug
I can't say whether you were lucky or not , or are better at tuning carbs than anyone else but from my own personal experience trying to dial one in and with info from someone I trust I'll never buy that specific carb ever again and I'll steer anyone I can away from it, not worth the risk in my opinion. I'd as soon run a holley instead of the performer 750 .

Its not just a moparts thing- A google search will turn up results from enthusiasts of all makes that found the Edelbrock Performer 750cfm carb just does not deliver the goods. When Edelbrock started the Thunder series they skipped over the 750 capacity and made their biggest carb an 800.
Keep old mopars alive.

Yep. I like that too.
750 = crap. I had two and hated them both.

I just rebuilt an eddy today and let me tell you this POS won't work at all! No idle and no amount of adjustment or tunning helps at all. Have rechecked the float adjustment three times to no avail and one of the air-fuel adjusting screws can be screwed all the way in or all the way out and in ur pocket and it changes nothing! I have checked and re-checked everything that can be checked multiple times and it just simply is a total pile!
If the adjustments don't do anything you put it together wrong or it's not installed correctly. It's impossible for a correctly built and installed carb to curb idle with the mixture screws all the way into their seats.

My friend has a '68 Runner that just plain will not work with that 750. It was a stock engine but since the installation of a Comp XE268 the problems with it have been exacerbated. He put it away for the winter with it actually running good and pulling pretty hard after he spent a ton of time cleaning and retuning that pos carb (but lacking the response it should have had still). Yesterday I went over to visit. He fired it up and we took it for a ride. It had no power and would not idle, just like right after the cam installation.
Luckily we tracked down a correct AVS for his car and are waiting for it to come in so he can finally ditch that POS.
Now I need to pin those needles, got to feel that heat

I have a quick question... Didn't these long ram intakes have the old AFB carbs with the narrow bolt pattern? Does the Eddy have a wide and narrow pattern or would an adapter be needed?
