hey i dont know a whole lot about carbs but i have a carter competition carb sitting on my edelbrock performer RPM manifold and i dont know if it is any good... heres a pic or 2.

heres another one... pretty much the same but maybe a better view... :lala:

From what i hear they are a cheap version of a 4 barrel carb. i don't know much about carbs. but thats my opinion

They're no Holley, but they're a pretty good carb.

It is the same thing as the Edelbrock Performer series carb. The part number on the bowl will tell you what CFM the carb is. It is a fairly high quality carb, easily tuned and just as good as holleys when it comes to reliability. The performance of it versus a holley is slightly worse, check out the other threads concearning Edelbrock vs. Holley carbs. These models are easy to rebuild, just use any Edelbrock carb part as long as the CFM rating matches. The part numbers for carbs can be found on Edelbrock's web site, the series is the 1400 series, and that one looks to be a 1405, but I could be wrong.

so.. its better then an edelbrock.

what does CFM stand for... i know NOTHING about carbs.. at all.

It is EXACTLY the same as an edelbrock. CFM is the flow rate of the carborator, meaning Cubic feet/minute. This is how much air / fuel mix the carborator can release into the engine in one minute. The higher the CFM rating, the more air/fuel mix the carb can potentially put into the engine.

Not true. Same design, but Edelcrocks are made with wayyy looser quality control and have several times over as many problems.

so im better then edelbrock and i should keep the carter and not switch over to edelbrock

I guess everybody has forgotten, but the Carter Thermoquad was THE carb of choice for many years, during the 60's they were totally the ****! A few years ago, Edelbrock copied THAT design for their "Performer series" carbs.

Since you have a real Carter, I would go to the store and get a book on it, and tune it up!

Just my $0.02! Hope it helps...

thanks! ill do that!


also

what would be the actuall difference between a stock manifold and an edelbrock performer rpm one...

SAY WHAT? The thermoquad is a TOTALLY different carb than the AFB that edelbrock copied. Thermoquads worked fairly decent when new, but the main body was made of a phenolic(plastic) material.. After years of use the phenolic would break down and you'd be stuck scratchin your head at all the problems it caused. Almost impossible to rebuild and have work right, cause the problem was with the actual carb body. Thermoquads were almost totally a mopar exclusive. They were a really strange carberator.

Now the AFB and edelbrocks are almost identical and most parts interchange. They are a very simple design and easy to tune. Very reliable. If its a daily driver you'll probably like either one.

You're absolutely right, I remembered (afterwards!) that it was the AFB that was copied, not the T-quad. Also, yes, the Carter's were almost exclusively MoPar.

Sorry for any confusion I may have caused, thanks for the catch chevymad!


Personally, I'm gonna get a JET modified Qjet for mine!!

man people hate edelbrock carbs on this board. I dont think carters suck...but like mentioned above its no holley

man i would love a phat holley with a MEAN blower sticking out my hood. i would just ****ing **** myself if i had one. i would probably spend 50 bucks on gas pulling out of the driveway.

(Note: Edited for previously noted improper reference to "Thermoquad".)

I'll add my "So what?" At the same time, dual point distributors and Polyglass tires were the hot ticket. Don't see many people running either of those these days.

Actually they're pretty simple to rebuild.

They have a reputation as a Mopar piece, but Ford used them briefly and International Harvester used them extensively. Carter even made the 9800 and 9810 Thermoquads (with and without EGR respectively) with Chevy linkage as Quadrajet replacements.

Thats rebuild AND work right.. Usually theres some kind of problem with the phenolic body that rebuilding won't address.

They're not too forgiving if they're abused, they'll chip and crack, etc. but I've played with a few of them now and never had a problem. They're just something different.

what about my other question.. whats the diff between a stock manifold and an edelbrock performer RPM one.

The idea with aftermarket manifolds is better and cooler fuel mixing and distribution to the cylenders. The stock manifold has uneven distances between the carb and the ports on the heads, which causes some cylenders to run leaner than others. It also hugs the block, allowing the manifold to heat up very quickly and very limited abilites to dicipate the heat. The aftermarket has seen fit to try and solve the uneven distances by using a higher rise design, or a systematic pathways for the A/F mixture to get to the heads. The mainly aluminum design on aftermarket intakes allows for better cooling, and some (like the Air Gap RPM) have an air flow passage to help keep the A/F mixture even cooler, resulting in a dencer mixture. The power gain will be noticable with any non-stock design aftermarket manifold, but my suggestion is the Air Gap from Edelbrock, as it is the best one I've seen for the money. It costs around $200, while the Performer is around $120, and the RPM at $150.

THANKS FOR THE TIPS!

If you put a thermoquad on your 301 chevy with polyglass tires, set the dwell on yer dual point distributor, all you would have to do to get traction is put on air shocks and shackles and you would have one grovy ride.

Sorry if this question has been asked a billion times, but why is Edelbrock not a *** choice? I've been told (by Ford guys) that Edelbrock is a much better choice than Holley as far as reliability and ease of tuning. I want a good carb for street and strip and can convert from my 305 I have now to a ZZ4 350 I plan on swapping in. Any suggestions?
