Well, I knew it was going to drink a lot but this is silly. I have a 2nd gen. with a 400 Pontiac and a Holley. I drove 20 feet up the drive, 20 feet back and let it idle for about half an hour to warm up before checking the transmission fluid and setting the idle. It used 2 gallons of petrol (gas)!!!!!! that's big English gallons at about $7 each!!!! Time to strip the carb.
Yes, and most of the guys here think its dear reaching $2 a gallon.
Seriously, are you sure it doesn't just need setting up? I put a LT-1 motor in a friends Camaro and that drunk 2 pints just firing it up and running several seconds. Just check that the needle/seats aren't leaking. I found a backfire could cause Holleys to stick, and excess fuel weeps into the motor. It Idles real rough. Look into the carb while it is running, and check the secondaries also. HTH
One way a Holley is far inferior to a Q-jet:
Fuel economy. The small primaries on a QJ lend themselves well to good fuel economy.
Not to mention better performance, overall idle quality, etc, etc, etc, etc, etc. Joe--ASE Certified Parts Specialist & 10th Ann.Club Tech Director '80 Carousel Red Turbo T/A, 26k orig.

Not to argue, but if you know how to set a Holley up, it will far and away exceed that performance of a Quadrabog. One of the old 440s we had got almost 17MPG with a vac secondary Holley 750, and a 396 Chevelle I had as a first car used to get a carb a paycheck it seemed to play with..ended up with 4 carbs for it, and the Holley, far and away outperformed and sipped the least fuel. You dont just take them out of the box and bolt em on...:)

--Which is the primary reason they suck in the first place :). It's trying to be everything to everyone :).
Well known that a Q-jet outperforms any Holley hands down. There were a handful of GM products that used Holleys originally.
Newsflash: Mostly marketing. Back in the hey day it was cool to have non-OEM equipment. In the same way the Hurst logos were put back on shifters after being removed a year or two due to corporate edict.
The fact is that a Q-jet is a superior carburetor for 99.9% of the GM vehicles it is original equipment for. My Q-jet will outperform, outidle, pass the gas station more and look correct than any Holley.
Take the 17059263 out of the box, put it on, adjust it and it just fits. No hokey linkage problems, fuel line issues, hardware store bolts/adapters, or any of that crap. It fits because it was designed to go there. Period :).
Something to be said for a company that sold 5 million carburetors a year without advertising :).
