Greetings,

I am finally returning to my project after an extended period of unemployment. It is a ’73 Plymouth Gold Duster resto-mod. Power plant is a warmed over ’99 5.2L Magnum. Block is bored over 0.03” with a higher duration cam (duration @ 0.05 216 intake/224 exhaust), hypereutectic pistons, heavier (LS1) valve springs, and double timing chain, but otherwise stock. Goal is right around 290-300hp.

Intake is an Edelbrock RPM Air-Gap (7577) manifold. I would like to run a Thermoquad but have heard they are not compatible with this intake. The Edelbrock guys suggest a 1407 (manual choke) or 1411 (electric choke) 750 cfm carb. I have also looked into the base 600 cfm Summit Racing carb or a smaller Holley (4160 or similar).

My question is this: What carb would best complement this intake? I have been advised to try and stay within a range of 600-700 cfm. This is a low budget build so high-end or exotic carbs are not doable.

Thanks for any and all opinions.
 
i would use the 1406 edelbrock electric choke. you can find them cheap all day on cl used and the rebuild kits are $40 , easy rebuild. new will run close to $300. i think any bigger then this would be to much carb for your set up in my opion.
 
stay away from the eddy 750 performer carb.....the 600 performer is pretty good carb....

for the best performance use a holley 750
 
I disagree with the Holley being the best carb. IMO, use a Edelbrock Thunder series AVS carb @650CFM. It is a jet it, set it, forget it carb. 750CFM is to much carb.

In the end, you must be happy with the carb on top.
 
I've tried a brand new 650 Eddy, and a borrowed 750 Eddy and never could get great performance out of them. Everything was set on the carbs but they just didn't have that "punch".

Saved up for a Holley 750 HP carb and I sure glad I did. Eddys get the car where you want to go.... car shows, groceries. lol
 
Want the most power from a square bore, run a Holley anywhere from 600-750. A 318 would run well with a 600 cfm.

Carter/Ede carbs are decent, usually pretty easy to get running. They just don't seem to put down the power that a Holley does. Run away as fast as you can from a 750 ede...

TQ's are good but really finicky in my experience with them. Won't bolt straight up to an air gap without an adapter.
 
Carter is an edelbrock. Edelbrock bought them out along time ago.
Only use a holley if you are going to drive it a lot. Holleys dont like to sit because the fuel will sit in the bowls.
 
I've run Carter 600 AFB carbs for many years, and they are hard to beat on an everyday driver. They start and run smoothly under almost any conditions, and you very seldom have to touch them after you get them set up for your particular application.

However, if you want to bring home some respectable time slips from the strip, pop the Holley on there and go smoke some hides.
 
I too would like to know what is wrong with the Edelbrock 750 Performer since I already bought one. I had no performance problems with my Holleys but plenty problems maintaining them. I had several "backfire" and had to be rebuilt. They also leaked and were new. My experiences with Holleys were not good but I recognize for others this has not been the case. Whey would the Edelbrock Thunder AVS be better than their Performer?
 
Tuneable air door. This stops the momentary lean condition when you "wack the go pedal" because the air door is tuneable unlike the AFB.

I so have to disagree with this except that a 750 is to much for a 318 in most cases.
 
Speaking of which, I wish they would come out with a set 400'cfm car s again for the small engines.

Crackedback, since i use one of these 750 EDE´s 1407 - can you please tell me why you have this bad opinion?

Thanks!

Michael
 
Search the internet about the 750. The metering in them is not good.

ede and carter carbs are fine if you put 2 of them on something. As a single, a holley of the same size will make more power, BTDT on multiple cars.
