Hi ; I've just picked up this carb and would like to use it on a 462 fresh build . I see it has a rebuild sticker on it with a Quality Re-manufacture tag with a # 16-249 and a date of 9/14/15. Is there a company named Quality Re-manufacture or is this a generic sticker used by rebuild comp.? I know it ran great on a 79 T/A w/a 400 but engine blew on it . Any info on this would help greatly !!! Thanks

It might be a rebuild by Champion Parts Inc.
A google search on that tag number returns a hit for 77 to 79 Trans Am, Including 77 with 2.93 Rear Axle.

Thanks for that info , from what I've found it appears to be a 800 cfm ? Is that possible ?

Nice carb except been thru a commercial builder.  I use the same part number on my own engine and to date NOTHING will make more power on the dyno or out-run it at the track.  There has been many contenders over the years but the ugly 1977 Pontiac Q-jet is the winner.

It actually flows 850cfm if you set the air door angle as shown in my book.......Cliff

Thanks Cliff ; I did notice the sec throttle plates look like they don't open up at full throttle but that was just a quick observation . I haven't had a chance to look at closely but I assume they should open all the way ? Also I have to put an E/choke on it . Will one transfer from another carb that is nearly the same model by chance ? Thanks again Cliff and I cannot wait to get a chance to run it on my 462 .

Stock it's emission calibrated and would need some help to work well on your 455 build.

Remanufactured who knows?  They can be OK to PATHETIC in quality control and often "butchered" up some with lead plugs driven into the bypass air passages, and even the threads drilled out for the N/S assembly and some POS double "O" ring deal pressed in there.

I try to avoid anything commercially remanufactured if I can help it.

I would not mess with used E-chokes.  Every one I've installed has taken a dump so we quit putting them back in place several years ago to save customers a little money.  The few times I did they crapped out within a months or so and we ended up having to replace them with new ones.......Cliff

Thanks a bunch Cliff . It worked great on a 400 T/A but someone shipped the car to Mi. in the dead of winter and failed to put any A/freeze in it before it left Texas . It ran a very short time a couple times until the steam started . That's how I came up w/the q/jet . I wanted a carb to test my 462 on the dyno that I was pretty sure it ran . I don't have a car for the engine as of now but I wanted be sure it would run when I do get it in something . I was already getting the engine ready when I sold my Bird and I need something to get in and out of a little easier .

Hey guys : I have another question about this carb . I want to use it on a 72 iron intake and I would like to know if I should use a base gasket from the 77 or a 72 base gasket ? Thanks again !!!

[Sonny]

I would first try the base gasket that matches the carb.

[Cliff Ruggles]

I would use our 1/4" thick open gasket.

The later gasket isn't a good fit as it has the "D" shaped openings, and the 72 gasket is thin and 4 hole.

I used the 1/4" thick open gasket for those set-ups as it allows one side to see the other which helps some much like having an X or H pipe in the exhaust.....Cliff
