I don't have first-hand experience but Cliff literally wrote the book on Quadrajets. I've had that book for at least 20 years.

 

Sorry, but Cliff's book is not 20 years old, the copyright is 2006. The Doug Roe book is the one that's over 20 years old.

 

Coming from the Pontiac community, he is the man for Q-jets. A few have complained about his work, but the vast majority love his q-jet mods. Most of the complainers are mechanical secondary Holley fans, which, for racing you cant deny the benefits.

 

As of July 2019 Cliff is downsizing and is no longer doing rebuilds. Just concentrating on sales and minor repairs.

One of our moderators here does excellent rebuilds to what you need.

$250 and that includes the rebuild kit

What Ed said. I need a Qjet to support a 600 hp rat , so I called Cliff this summer and that is the reply I got.

BTW, has anyone here heard of Harold Bettis? I happen to have a race Qjet built by him on loan from Mark Jones. My transmission folks ( AutoGear M23z) knew all about him. Called him a "flow guru".

 

If Cliff isn't doing them I would look into Sean Murphy Induction.

 

I've heard nothing but good about his q-jets

Cliff took a while to get the carbs done, but I needed one done on my truck pretty quickly. I drove there with the intention of leaving it there, but with a little nudging to try to persuade him to get it rebuilt quickly. He rebuilt it while I waited, and he did a nice job. Nice guy.

The MAIN problem was that the car talk stuff started and I totally forgot about about the wife in the car. That did not go well...

 

Are you looking to have your carb rebuilt or fully restored?

Tom can take care of you if you're looking for a rebuild. If you're looking to have the carb restored, I can help.

Here's a 7040204 I restored.

 

Do you do any performance stuff or do you concentrate on factory correct?

What amount of power do you consider a Quadrajet capable of?

 

I will do mild performance work on Quadrajets, but I don't get into full race type builds on them.

Properly set up, a QJet can support 600+ without trouble, but at that point the modifications required start to detract from its driveability manners.

 

Yes I've bought a few things from them. I once bought a built up Pontiac 462 that I flogged for 75,000 miles without any issues. Its still running out there today.
He topped my motor off with a special Brad Urban/Cliff Ruggles built Quadrajet. It had all the cool little things like adjustable TPS.

Cliff is straight up, your not going to do better..

You might want to have him install a "ported" vacuum port for vacuum advance. Many people out there mistake the timed port as ported.

Also see if you can get the TPS adjustment..

You will wait though..

He sells a book with his rebuilding tips..

 

By TPS do you mean APT?

 

I think that's what he meant. APT comes on all edelbrocks and on 76-78 quadrajets. They are also all 800 cfm.

 

The older Qjets had it in the base. not sure of the years 68-74-5 maybe. Newer had the plug you can knock out of the top & thread in a screw or plug.

 

The ones with the APT in the base usually have the tiny screw frozen tight and very difficult to get loose. Cliff says he has some success getting them out by his method.

 

Thanks to those who posted kind words about me. You're appreciated, believe me.

I don't do restores because of the chemicals needed for coloring. not home shop stuff.

Von is right about the little needle screw. I've kinda given up those. I did get one loose a year or so ago. Used oxy-acetylene torch, with much time and WD-40. ran my oxygen bottle dry. I can usually get about anything apart but the time is the killer. I had like 4 hours in that baseplate APT screw, no real good way to bill out anything like that.

Beth, see PM from me.

 

Re: cliffs high perforance



Saw it and email sent

 

Nice pic of the Adjustable Part Throttle feature.

I wonder if Edelbrock used stainless screws on this ?

 

Are those upper rear flaps modified? I have only seen that kind of thing on Pontiacs, and they were square.

 

you can, I have, but it won't necessarily work. I've had them to where a low viscosity fluid like WD-40 would run right through but I still can't get the screw to turn. I've broken the screwdriver slot in a couple trying, not to mention a few nice pocket screwdrivers.

 

If you want quick turnaround, likely ten days, I use and suggest www.customrebuiltcarbs.com Your carb will look and run like new and he'll do some custom work as well, the shop is in NJ. Click on the link and give them a call!!

 

So I sent a Qjet to Cliff in Feb 2019, he would never actually ever verify if he ever received it,,always tell me he was running behind,
then he told me all his employees quit on him, so he was solo,,,he has had my carb for 8 months now and has not started on it.
I finally told him to just send it back to me. He said maybe Mark at Quadrajet Power could help me and he supposedly sent it
to him. I looked at Marks website and he is saying 10 week lead time..... I dont really even know where my carb is at this point!
since no one has ever had the common courtesy to tell me!

anyone have experience with Quadrajet power?

 

I have another question, is 1500 dollars too much to pay for a "restored" 7037203?
I need one badly

 

Absolutely. Just send your carb to SMIcarburetor.com and they will do it for about $500

 

Click on the link I provided and call, I'm sure they can help you!!

 

yes, too much. way too much.

 

let me clarify,,this is for the carb all restored and ready to bolt on,,I currently do not have a 7037203

 

Just be patient; they show up on ebay all the time.

Here's one !

https://www.ebay.com/itm/1967-Chevy...=13022969666&hash=item5b55fd4176:g:-MgAAOSwmvtcmTjM:sc:USPSPriority!37206!US!-1

And another one :

https://www.ebay.com/itm/1967-CHEVY...JET-4BBL-CARBURETOR-7037213/132889721215?hash=item1ef0d8397f:g:STgAAOSwADxcFbFq

Once you have a carb it's about $400-$500 to have it restored.

 

Thanks Beth but those are both 7037213,,i need 7037203
and those look like later service replacements
I need an original with the disc containing the P/N not stamped into the body
there is one on Ebay but he wants alot for it:
https://www.ebay.com/itm/1967-Chevrolet-Camaro-Rochester-Quadrajet-Carburetor-Remanufactured

 

"13" and "03" are both Chevrolet. Is the 13 a service replacement that isn't suitable for a show car ?

I'm glad I'm not into show cars LOL

 

true, however the parts catalog clearly states my 67 AIR, Manual trans shall have 7037203
so thats what I'm putting on!:wink2:
even though my car is a documented 1 owner car,,the carb thats on it is clearly numbered for a '68 BB
the owner tells me he never changed it.....??? go figure:surprise:

 

I see that in mid-68 they switched from a circle tag to a stamped vertical number so the "13" has to be made after 1967.

Keep looking, I'm sure one will pop up on ebay at a reasonable price.

You could also just buy one just for parts and just use the body with the correct circle tag on it and use the parts from other carbs.

 

I have been looking for a year have only seen 2 come on ebay,,this one for 1500 and some other rusty piece of rubbish for like 600 dollars
yes a nice disc would be good to transfer! although I have been told most of them have been sandblasted when overhauled back in thday
both of the ones I have seen suffered from this
