Hey guys

I have an 83 camaro with a 305 4bbl the probllem is that the carb(stock quadrajunk) is shot. im in the market for a new carb/intake/carb spacer. My ? is which ones would you reccomend. Im leaning towards eddlebrock because i heard holleys need constant adjustments. i also figured it would go good with an eddlebrock performer rpm intake with a 2 inch spacer. but im open to opinion. let me know what you think. thanks in advance

btw the motor is bored .030 over with flat top pistons and mild cam
it has about 18000 miles on it

Just in case you didn't know, Edelbrock and Carter carbs are virtually identical. I don't know of any differences between the two, besides the fact that Carter offers some cfm ratings that edelbrock doesn't and probably the other way around too. Personally I have a 625cfm Carter carb with electric choke and a weiand action+ intake. I'm happy with both of them, but can't say how they compare to anything else really because they were what I put on when I put a V8 in my car. Before that it was the 2.8L V6. I've heard good things about the action+ intake, which is why I am using one on my car.

 

Hey thanks for the info... yeah i realized carter and eddle are the same i was just lookin for some opinions but thanks again man

Holley's don't need constant adjustment. With a mild cam and stock heads on a 305 I would do the action+ like he said above. My preference on a carb would a 600 vacuum secondary holley. No matter what carb you get, you will need to tune it. A holley is easy to tune. Unless you have a short air cleaner, you will hit the hood with the 2 inch spacer. My stealth intake and holley carb with 14x3 K&N drop base is about 1/4 inch from touching the hood.

ok edlebrock is the way to go(if you can get a good one!)(personal experince!) anyhow yes, holleys need constant adjustment! but,.. edlebrock and carter are almost the same!! the difference lies in that the edlebrock is a squarefalnge carb, but, its a spreadbore design(look at the throttle shafts!
under-neath the carb! note: the secondaries are much larger! and the carter are all the same size! just some food for thought! id go with any goood dual-plane ! weiand stealth, performer rpm, just to name a couple! as for a spacer a wood one is good because it nullifies heat from getting to the gas! 1" should be more than enough! keep in mind the intake need to go to at least 5500 to get anything out of it!

83camaroman,
I'd like to help if I can. Have you seen my other posts so far? I do carb mods and supertuning with Edlebrock equipment and run it on my own cars... though I have no association with Edlebrock. The EDL carbs are not identical to Carters as has already been stated, but there are some other features that make the EDL carbs better and more adjustable on a modified engine. I have a list of 20+ mods I can do to the carb and other mods in the works for the dualplane intakes. So far I am not into production stage for this stuff but still collecting data so I have some realworld numbers to claim as gains.
I will say that so far the mods have worked excellent for my own cars, and I'm anxious to do tests on other vehicles as well.
For now I will recommend the Edlebrock-RPM intake and #1406 carb, along with a 4-hole one-inch spacer. Avoid the open (one-hole) spacers like the plague...they are not meant for your type of engine/application (huge difference).
feel free to email me with carb questions,

 

Camaro,

I absolutely detest Carter carbs....and so hate Edelbrocks carbs too.

Holley carbs make more power. Period. Go to the dragstrip and find me a bracket racer running an Edelbrock carb.

There are only 3 in the free world, and that's just a rumor.

Everyone else uses Holleys. They are dirt simple.....and need service occasionally only because they hate dirt - so use a good fuel filter.

A 650 Holley double pumper on top of an Edelbrock Performer RPM will make max HP. For a mix of good power AND mileage, go with the 600 CFM vacuum secondary Holley on a Performer intake.

Good luck......and people who swear by Edelbrock carbs because they had a bad Holley almost EVERY TIME had a maladjusted, full-of-dirt Holley that they couldn't tune properly. NOBODY makes a carb that's perfect out of the box for every engine. (pre-tuned especially for YOUR car).

Get the Holley, a tuning manual,(available thru Jegs), and a good filter. Trust me on this.

Box,

Aw, c'mon!? They're not so bad. Just 'cause there's about thirty metering rods and air bleed tubes hanging down when you lift off the top section, and they are so sensitive to changing temperature that they practically need their own air conditioning system, that's no reasone to "absolutely detest" them - well, maybe a little.

They are a PITA to get properly adjusted and keep that way. They are probably just as contaminant sensitive as Holley, but I think they meter fuel better in the intermediate ranges. There is a lot more to adjust in the idle transfer and low main circuits than on a Holley, which makes them more complicated.

I'm a little surprised that no one suggested keeping the Rochester and tuning it for the engine. A Q-Jet can meter fuel fairly well at the low end, and can be made to deliver a lot of mixture at WOT. And, they're fairly simple. They have their shortcomings, but aren't necessarily a bad carb just because they came set up to feed a moderate engine. If you've modified a few other things, it may make sense to modify the carb to match the changes. It certainly would be cheaper. And a lot more reliable than a Carter ThermoQuad....

Personally, I prefer Holley for any kind of performance-oriented application. I can tune a Q-Jet with the best of them; problem with them, though, is that all of the more recent ones are basically unmodifiable in several areas crucial to daily-driver use when matched with a big cam (idle passages especially). In fact, on the newer ones (704 numbers and up) some of the carb's internal passages are actually smaller than what the metering orifices need to be that they lead to. The CC ones are the worst about that. But, all the 702 series carbs many of which will support a lumpy cam, are 30 years old now, so they all have worn out throttle shafts, stripped screw hole threads, bent air horns, missing and mismatched parts from going through production-line rebuilds, etc. etc. etc. So yeah sure you can get them to do OK at WOT, but the rest of the time they suck.

I dislike Carter carbs too, including the Edelbrock. I have never found how a 1406 or any of its siblings is different from any other AFB in any way other than being chrome plated and having Vic's particular calibration in it; it's still just an AFB. I'd welcome any info on how they differ. Still, anything that uses a weight as the calibration part for secondary fuel metering is too crude for me. Even Rochester quit using that Stone Age system when they retired the WCFB (Weight Controlled Four Barrel) in the mid 50s.

For your application I would recommend a Performer or Action +, a Holley 600, start out with no spacer, and a non-drop-base 2" air cleaner or better yet a stock HO dual-snorkel cold-air one. The drop-base ones all locate the lid of the air cleaner so close to the air horn that they simply substitute the restrictive lid-to-air horn slit for the restrictive filter. Then if that fits, measure the clearance, and install a 4-hole spacer with small holes, the same size as the carb's throttle bores, of whatever thickness that will just barely allow the breather to clear the hood.

IMHO the Performer RPM is too big for your combo as long as you have the stock 416 heads, especially if they are unmodified.

BTW if you have the oil pan off, you should lose the high volume oil pump. It's doing more harm than good by aerating the oil and using up horsepower and gas that could be better used pushing the car around instead of wearing out distributor gears. Use a regular M55 with the Mr Gasket high-pressure spring in it instead.

What cam have you got in there? That may impact the other choices.

Carter is owned by Edelbrock! Of course they are damn near the same, In fact the new ones are almost the exact same. I think the only difference is plated or polished.

I like the Predator carbs. I've got a holly on my truck and it's ok but I'm not going to mess with another one ever again! I borrowed a friends predator for a week to see how I liked it. I didn't want to give it back. I have never had that kind of power out of that motor and got 3 mpg better than the holley too. Damn things aren't cheap though

 

Carter was not always Owned by Edlebrock. The two carbs look the same on the outside primarily because they share the same aluminum body originally manufactured by Weber. Many parts such as jets, rods, etc do interchange for that reason. They are however different enough to be classified as different carburetors. The Edlebrock line was made for performance applications on modified engines, where the Carters were originally factory replacements.

Bor, sounds like a shootout is in order? I am willing to do controlled vericom testing on my camaro with any Holley carb of your choosing vs my Edlebrock carb. I will also soon be able to perform an accurate fuel mileage test when I finish constructing a custom fuel tank. I am willing to do a fair test, and I would personally go with the carb that performs better. What do you think?

I'd consider joining that one too. I'm not going to go so far as to insist that you change carbs; but I'm fairly sure I can get a Holley to run better (more HP etc.) at the same gas mileage.

WOW!!

Seems like you guys are really torn between carbs. I have been going to the local performance shops around here and they have almost all reccomended Holley for the best all around performance. They agree with some of you that they dont need all that much adjustment after the intial one to get it to match the car. They are going to give me a good deal on a 650 double pumper and a performer intake so i think thats the way to go. They also reccomended the spacer plate but i dont think ill have room for it. maybe a low profile dood scoop or something?? what do you guys think?? worth it or not?

thanks again


BTW the cam is a mild one. I dont have the specs on it right now and i didnt know much about motors when i had this one built. (I did a lot of the work myself but had my mechanic friend help on whatever i didnt know)
