Honestly, bob you're becoming one of my favorite members now. The fact that you took the time and effort to get your q-jet running right instead of just jumping on the bandwagon earns you much respect in my book.
Funny comments like that will keep you there.
I've actually been kind of curious if I can make a bunch of Mikuni carbs work with my C3... now THOSE are the best carburetors you can get.

As far as the "Mahoneys"
go...your talking to a life long Snowmobile rider... The mikuni has always been the staple of any sled I have owned, 90% Arctic Cat

As I understand, this means that is it a 79 quadrajet for 49 states, off a manual vehicle, though I don't know what the second row of numbers is. As a side note, it has another sticker on it that states it was rebuilt by Holley, with these numbers:
7160AA
1403-8506B0
17059203

I have heard that Holley has a habit of screwing up their reman 'Jets.
When you have the carburetor open record the numbers on the rods and jets.
What sort of engine is this carburetor on?

Weber are even better and there are kits made to fit. As close to FI as you can get.

I would love to see you meet Lars face to face and let him show you how to make your bastardized Corvette run properly with a Qjet
ps: Nice hole in your hood

The Lars paper lists the proper jet as a 77, but that I should start about 2 above that for the headers, so 79?

:there is no way you are increasing 104hp from a simply a carb change unless the Qjet was set up so poorly the car barely started and ran at all. You can tell me that until you turn blue in the face and the cows come home I won't believe it.
Either the Qjet was incredibly poorly set up or there were other mods in addition to just the carb.

I don't know what this Quick Fuel thing is you're talking about but it sounds like a third party smoked over Holley that has had a little tuning done to it. Kinda unfair putting this thing up against just a rebuilt 'Jet. I guess you just have to settle for this kinda stuff when you can't tune it yourself. I'll bet they sold you this thing because THEY couldn't figure out how to get the airhorn off the 'Jet didn't they?

Lets put it this way, I'm 21, work in IT, and have only had my vette for a year and a half and I got an EDELBROCK q-jet (1904) and got it to work on my '81. Granted I had a few adjustments made by Lars to make it run even better, I still had to do a few things myself first. If someone that's been working on cars for longer than I've been alive can't get a q-jet to work, they must have some serious mental disability.
BTW grats to bob on making that old core of a q-jet mostly work. Twas really cool basically watching as you came back and forth asking questions about it.
Oh and since mikunis and webers were mentioned. Both are AWESOME carburetors, I'd love to run either on a vette, actually. Motorcycles run them and they work great for those. I just wish there was a 4 barrel or a big cfm version so you wouldn't have to use so many at once.

KMA? Listen to yourself... I dont appreciate that at all.
How old are you. 17?
At least I am open minded enough to appreciate Holleys and Rochester for ther ups AND downs
Go race with your quick fuel 750
I outgrew that tough guy stuff years ago....
Goodbye.

You are correct about the carb, it was literally pouring gas out of it and flooding all over the intake manifold. I had a 1/2" puddle of gas on my intake manifold. I imagine if my Q-jet was rebuilt correctly they would have been closer to each other.
I didn't mean that all Q-jets are junk, my buddy has one on his 72 Granville and loves it. My father in law is still running his Q-jet on his 80 vette and it runs ok. It idles irratically but I think that is more timing(dist gear) then carb. I just prefer the 4150 style double pumper style of carb and some of you seemed upset about it. If I was keeping a stock Corvette I would run it, but as you can see from my pic I am not.

Heres what I said
"I would love to see you meet Lars face to face and let him show you how to make your bastardized Corvette run properly with a Qjet"
Lookup bastardized in a dictionary. : to reduce from a higher to a lower state or condition :
There you have it.

If that is what you meant, then taken from a higher to a lower state is a matter of opinion. Since before in the original state I could not go faster then a Honda Civic Si, I would say I have moved to a higher state since I have 2 1/2 times the HP, twice the TQ and a one of a kind set up. If I had a C2 with a 396 or 427 I would have left it stock.
Where you like many are more concerned with the original state no matter how poor the performance. Personally I obviously prefer the performance aspect of it. I feel a Corvette should perform like a Corvette. The base 350 Corvette engine was no different then the 350 in a Chevy pick up truck. Now I have a 11.7:1 compression ratio, 383
Stroker, 65 cc Aluminum heads that goes right up past 6000 RPM no problem. To me that is performance. So I guess we will just have to agree to disgree.

To each his own
Like I said, If I want to go fast and dust every ricer in town (which I have no desire to do anymore) I would take out my 70 ElCamino SS LS-6 ..which was 425 HP before a few add ons.

Next will be a L88 hood and a paint job. The scoop was a temporary thing until the paint job money was stored up. All I wanted to achieve was over 400 hp, now with the ZZ 383 hydro roller cam, heads, Keith Black flat top pistons & 383 I am at over 450hp. There were a couple of racers in 1972 that had the same pipe set up as mine with a L88 hood. When I do my paint I think I am going to do a retro of one of those cars. Here is the one i am leaning towards, also this is in the corvette hall of fame so I dont see how a retro of it could bring down the value. http://www.motorsportcollector.com/CAR57Corvette.html
