Talking to rebuilders I called National Carburetors and they gave me prices that appear good. Has anyone used these guys before? I know that sometimes inexpensive is cheap!
thanks in advance

I don't know them but be very careful about general rebuilder places. Almost every time you will get a carb full of mismatched and inferior parts. Its one of the drawbacks to the Qjet as its no longer produced.

Seek out one of the known builders who specializes. I know Cliff is booked solid but I believe there are a handful of others out there who can handle the job for you. Maybe others can chime in with suggestions on alternative places. Where are you located?

Bowties are for Pee-wee Herman. "Chevy": even the name sounds cheap, but not as cheap as your Pontiac will be with an LS transplant.

I've used benchwick carbs in youngstown, ohio for a lot of carb work. Never had any problems with his work.

I've had him do run of the mill work but i've seen some of his crazy six carb show setups too. Nice down to earth guy.

I wish I could put you in touch with an actual user, but I can't. But I'll share what info I can. Cliff Ruggles is considered by many the utmost authority on Q-jets--He wrote the book. And I have great respect for him. However, unless you are willing to get in line and wait, you'll have to buy from someone else, send your carb to someone else for a rebuild or do it yourself.

Until you are familiar with the Q-jet, I don't recommend doing it yourself. So, I've heard Cliff infer that many, if not most, large carb rebuilders, do not produce a good quality Q-jet. I can't say one way or the other. Of those who advertise Q-jets online. I have heard good reviews of two of them. One is Everyday Performance. One of their guys posts over on FBN. I really like the looks of the 800cfm 1971 Buick 455 Q-jet on their site. I think they will also rebuild customer carbs.

http://www.everyday-performance.com/quadrajet_carburetors.htm#!/~/product/category=578011&id=33759629

I've also heard good things about SMI. One of the resto parts dealers offers SMI Q-jets. I believe it's OPGI.

http://www.smicarburetor.com/products/sfID1/28/sfID2/9/sfID3/100/productID/841

http://www.opgi.com/gto/1969/air-fuel-delivery/carburetors/G240411/

Now, I've mentioned that we raced the '68-'70 model Pontiac Q-jets. That was before a lot of the smog laws took effect. So these carbs don't have a lot of the restricted passages which the later carbs do. Cliff shows in his book which passages need enlarging. But it appears that it would almost take the skill of a brain surgeon to do it right.
So, it is not likely that many of the big volume rebuilders would offer a Q-jet with these mods. However, if they have good rebuildable '68-'70 cores, there is no reason why they couldn't rebuild a decent quality product from one of these. TJ and I both rebuilt LOTS of these, which worked great for us, street and race. There is a picture of one of these on the cover of Cliffs book.

http://www.ebay.com/itm/like/380872845788?lpid=82

Having said that, I'll mention that, at least one rebuilder advertises these '68-'70 Pontiac Q-jets. And the picture they show for it is correct. Now, as to whether or not they actually have one of these in stock for sale or not, I don't know. And, if you order one of these, will you get the older carb or what they consider a suitable substitute ? I don't know.

Then there are 2 rebuilders who show the early Buick carbs at low prices. I know nothing about either one.

The following picture is correct for the early Buick carbs, with slashed vent tube.

Thanks cortcomp & bigD,
Big Bummer! the '69 Pontiac Quad must have been sold before I could get to it.

I talked with a guy at SMI Carburetor and liked what I heard. They are only a couple of hours away so next time I am that way I'll stop by. They are 4-6 Weeks out and about $400.00 for a mid 70's Quad.
I called National Carburetors, they had a great price and Lifetime Guarantee. The problem was that they wouldn't confirm the core. I was wondering if anyone had any experience.
I have a call into Cliff and should know more after hearing back from him.

The mid 70's carb have some real advantages. I'm running one from 76.
If you don't already have one, get a signed copy of the Book from Cliff.

Most '71 up Pontiac carbs have a huge "smokestack" vent tube, which requires a hole for it in your air cleaner base.

I'll post some links to pics of these.

The 800 cfm Buick carbs don't have this big vent.

I just position the air cleaner and drill an apporopriate size hole that lines up with the "ocean liner funnel".

I found a Quadrajet from a 1976 Olds #17056252. Sorry I have been busy with life, the restoration of the car & other projects but collecting parts again.
Thanks for the help!
