Who do you recommend/ who is better for a prepped Holley street/strip carb.. The Carb Shop or Quick Fuel Technologies?

Quick Fuel's people are ex-Holley engineers.

Patrick at pro-systems is better than the 2 you mentioned.

My experience with the carb shop was they could not handle a std rbld on my stock 88 monte ss with L69 305 HO & electronic original to to car/motor q-jet.,ran like crap/terrible when i got it back from them.

I then had to take the time (which i didnt have much of at the time) to do it myself and it ran great after that,i was trying to save time by having the carb shop do it which backfired on me to the tune of $200. The problem was they had the MCS & part throttle mixture adjustments out of wack. Also,one of the idle mix screwes was not affecting the idle either way when adjusted and the motor idled on 4 of 8 cyls but other idle mix screw would kill the motor when i leaned it out. Once i got all that corrected the carb worked good but then i had to loosen the upper secondary air valve spring adj because it would not open much at all untill over 5k rpms,then the carb was working great all around after that,put a little kick back in the mioni mouse.

I would try Sean Murphy Induction or one of the other people recommneded in above posts.

i agree with bb485 unless you are in the habit of just giving money away id use patrick at pro systems if i was you . i have one of the dominators awaiting my new engine and from past exp with the carb shop im surprised they still in buisness and quick fuel is more like a band aid carb if you want true performance and a carb that done right the first time and a company that stands behind what they sell click this link here http://www.pro-system.com/or get in touch with mike lewis at lewis racing engines or leave a message for WOLFPLACE at team chevelle. i can promise you wont be dis satisfied at all and should you have a tech issue with your carb patrick himself usually picks up the phone . his carbs are top notch his service is first rate and his prices are verry fare considering all the knowledge and service that comes with a pro system carb purchase. after all its only your hard earned dollar your spending why not spend it in the right place the first time.

And the pro-systems looks purdy :D

I have heard bad about quick fuel, do not know about the carb shop, but have heard nothing but good about Patrick and Pro Syatems.

I know that Patrick will do my carb as soon as I have an engine to go with it.....lol

BTW, Jerry that engine looks sweet!

wow, interesting, I didn't know that the Carb Shop and Quick fuel had such a bad rap, and that Pro Systems was the place now.

And the pro-systems looks purdy :D

that whole engine compartment looks purdy . wish mine would stay that clean . :thumbsup:

One guy who "heard" bad things about Quick Fuel does not constitute a valid bad rap.
This is a problem with the internet boards.

Myself and 2 friends have had excellent results with Quick Fuel dominators. Excellent after sale service as well.

My engine builder uses them as well. With excellent results.

Don't know about carbs. but i have a quick fuel fuel pump, and i love it.

For what it's worth, My combo is.....470 cu. in., 10.5 compression, mild ported E-heads, 5200 rpm stall, TH400, 4.10 gear. 3625 lb. race weight.
I launch the car from idle, and shift around 7000 rpm.
I have run a 750 Race Demon, an 850 Mighty Demon, a Pro Systems 1050 Dominator that Patrick built for my combo, and a 950 Pro Systems built for a car similar to mine. All but the 750 ran the same ET and MPH. (the 750 MPH was 2-3 mph slower)
I recently installed a Q950 Quickfuel with no other changes. At Commerce 2 weeks ago, was the first time on the track with the Quickfuel. Literally, right out of the box, and in 3600 ft. nasty air, I posted a new best 60 ft of 1.42, and ran 6 hundreths and 2 mph better than it had ever run before. I never even set the idle screws! I'm sure it will pick up more with proper jetting/tuning.

I feel that technology as good as it is now, everyone makes good stuff. My car just likes the Quickfuel best right now. And it was $300.00 less than the Pro Systems.

This may surprise you, but there are a number of shops who call themselves "The Carb Shop" - so you will need to be more specific.

With great success I have used http://www.customcarbs.com/ they have dyno mule engines capable of testing just about any carb.

I know nothing about http://www.thecarbshop.com/
Or http://www.carb-shop.com/
Or http://www.thecarburetorshop.com/

Ain't that the truth!

No Kidding Bomber67. What carb shop are you guys talking about. The Guys that say they are no good are from the other side of the country. "The Carb Shop" in Ontario Calif I know about totally kicks a$$ IMO.. I have custom built 572 BBC and they tuned another 41 HP out of that Rat. Customer Service was great, They let me watch the entire dyno experience, Were very pleasent and bought me lunch!

WOW....did I open up a can of worms....LOL...
You are correct, one person does not constitute a bad rap.
As well as one person does not make a carb supplier the end all to perfection.

I was merely pointing out what I know to have heard from another person that has said he got very poor cust service, and a piss poor carb.
I have also heard that BG carbs come full of metal shavings, yet another guy I know has two of them setting atop a blown 383 and he can say nothing bad about them.

So, I guess someone needs to do their research and decide for themselves...and I see no problem with internet boards....you get a varied set of ideas and opinions, some good some bad, but one thing for sure, if we did not have these boards no one would have the opportunity to learn and pass their knowledge and experiences to others.

I wouldn't say that you opened a can of worms.

The internet and the forums are invaluable research tools - but one still must make their own decisions. No single vendor of custom built carburators can deliver 100% spot on carbs 100% of the time, but most quality shops should get real close on their first try. Its just that some shops have more data on different engine combos, making the first shot more likely. I know that www.customcarbs.com dyno tests 100% of their carbs on an actual engine before delivery to a customer. Their dyno mules are not a duplicate of your engine, but they do allow for a dynamic real world test.

Chevy fan attic, Bob and George Vrbancic are a couple of old time street racers made good who just love building horsepower. When they do dyno pulls I'm not sure if it can be said who is having more fun: Bob and George or the customer! I originally contracted with the Vrbancic Bros. for tuning on a blow through supercharged 468 that another shop said was maxed out because the 830 carb was too small. Without going to a different carb they "found" another 243 hp from about 6 simple changes!

I'll bet that if I looked further on the internet that I could find more than the four close to the same name The Carb Shop that I already listed.

Now that IS talent!!!!
Besides sweet!

Another vote for Pro-Systems here. I got a 780 cfm (4150 series) for my 377 and it pulls harder than ever. In fact, until I bolted on the Pro carb, I didn't realize how slow the recovery was after each shift with the old carb. I might add that Patrick's customer service has been great so far also.

**Disclaimer**
I have not run any other custom carbs on this vehicle. Therefore I can not tell you that one brand is better than the next. I will however continue to deal with Pro-Systems based on my personal experiences.

So Bomber67 We are on the same side Right? LOL

I hear so many great things about prosystems here, while I don't doubt there great carbs, it reminds me of the whole ultradyne thing. Not many people here have real data to compare too(a few do) and also how many people started out with an untuned carb to start with? Just like Ultradyne I think a lot of people fall into the hype easily ALSO on internet forums.

Saying this; any of the recommeneded carb tuners are a great place to start if you CANT tune a regular carb. Also if I was looking for a custom carb, it would be through pro systems as their price isn't bad and I have heard good stuff. Just seems like people tend to hop on bandwagons, but sometimes its for a good reason :)

FWIW, I have time slips with my old carb and some with the new. The Pro carb has netted me almost a tenth. I am not saying they are the end all be all, but because of my experiences with them, I will continue to give them my business. I will add a disclaimer to my post above........;)

Guys I know who use Quick Fuel swear by them, and all say it drives like a new car with them on. I know a guy who runs BG and will not switch he spent 4 hrs at engine dyno tweaking every ounce out of it. They are all about the same just what you expect is the variable.

wow, interesting, I didn't know that the Carb Shop and Quick fuel had such a bad rap, and that Pro Systems was the place now. We bought one from The Carb Shop and one from Pro Systems at different times and frankly neither worked as good as a stock Dominator carburetor. I think that Patrick's carb is only an air bleed mismatch but it sure makes the thing undriveable. Patrick's service is definately unmatched in the industry and he is always willing to answer any question you have. I'm going to try to get his carb to work on my engine when i put it my old '67 SS. The Carb Shop carb lost two tenths of a second when used on a 481" BB in my son's Chevelle.

OK I will sum this up from my point of view. Ready, I think what some of the poeple were upset with was there might be several companies across America that might use the exact same name. So if we are going to blanket party on a vendor just say which one "IE The Carb Shop in Montana" Thats all. Imo. I had a good experience with the guys in Ontario Calif. There are no doubt several places that are well qualified.

cody, what are you trying to say about ultradyne? Hype? Don't think so the the cams work as stated

I means The Carb Shop at 1461 E. Philadelphia, Ontario, CA 91761, the one you come across in magazines, etc. ..naturally. Not an obscure shop with the same name, that only a local would know, regardless of how good they are.

It has been an interesting thread, though people seem over-sensitive of others comments. It seems there is no strong consensus and everyone has a story that contradicts another's. Would still like to hear more experiences though.

Have any of you guys tried Allstate Carbs?

cody, what are you trying to say about ultradyne? Hype? Don't think so the the cams work as stated

Yes they work, but so do Isky, Comp, Crane, Lazer, howard etc etc etc cams. Personally I think ultradyne/voodo cams are great but people tend to praise them like they are so much better than all the others. Truth is I never once saw a legitimate dyno comparison independently done with an ultradyne cam v other aggressive cam. Yet there are loyal followers that swear that they are the most powerful cams available. Anyway not to argue about it but my point is that prosystems is a great company with a great product but don't get caught up in "too" much hype. People tend to hop on bandwagons, there are other great companies also sometimes people like to feel like they have the best, and think that it is so much better even if its all in their heads.

well harold has posted many times about his cams vs comps and they seem to do better. I agree there are many good cam companies out there that for 99.9% of the people couldn't tell the difference in the seat of there pants.

Mike,
I was going to mention All State carbs but, I didn't want to get involved. I have two of their blower 750 Holleys on my engine, they are great. They have great customer servive as well. I have suggested them to other people as well and everyone has been impressed. They have a "new" version of blower carb out and I am debating on "upgrading" not sure why because, mine work great. I would bet most people have never heard of All State Carbs. They are up in your neck of the woods, it might be worth a trip over to see and talk to them.

Carbs are one item that almost never are agreed upon. It comes down to tuning 95% of the time.

For what it's worth, My combo is.....470 cu. in., 10.5 compression, mild ported E-heads, 5200 rpm stall, TH400, 4.10 gear. 3625 lb. race weight.

Ken thats interesting, do you know what the differences are between your pro systems carb, and the Quickfuel?

I'd be interested in what quickfuel uses for air bleeds and jetting out of the box.

That combo runs! what are the cam specs, and whose converter are you using?
thanks
Brian
