if I remember correctly, the 71 T/Qs are a one year only style carb with the canted idle screws, but I would think that carb kits are still available from auto parts stores. I think the manual transmission 340 carb number is 4972, and the 340 automatic is number 4973, in case you need the carb...

I have a holley 770 street avenger, but I did not come with a CD, mine had a booklet. What do you need to know? Maybe I can help.

I'm not sure about baseplate modifications, and thats exactly where I am at, trying to find out for sure what needs to be done if anything. The information that comes with the proform main body does not mention anything, but they do give you different air bleeds to install if there are no...

I also have a holley 4779-2 and mine did not originally have 4 corner idle, so the secondary metering block did not have a power valve. I am in the process of changing the main body to a proform, and adding a different secondary metering block with idle screws. I'm only going to use this carb to...

Summit sells a kit to rebuild carter fuel pumps. ( it's actually made by holley)

I used to own an AAR cuda, so I'm very familiar with six pack set-ups, and my superbird I have now is a six pack car. If your car has backfired through the carbs at all, I would almost bet the power valve is blown and leaking fuel... My AAR used to do this on occasion, so I always carried extra...

very nice ! and clever !! you do nice work too.

either brand carb. can work just fine. It's all in the tuning......even thought I like holleys.

oh ok, thats exactly what I am doing.....I have a 750 HP for the track (no choke), and I run a 770 street avenger on the street. I do love the street avenger.

so the 750 HP you have now has no choke? Has the choke tower been milled off, or is the choke simply not hooked up? Why not stick with the same carb, if your car runs good with it, and get a choke back on it, even if it means replacing the main body for one with a choke? You can find main bodys...

what intake manifold are you using this AVS on? Is it the correct 69 340 intake?

X2...other than A/C cars it was used as anti dieseling device, and is found on many original 68 to 70 cars with AVS.

I would have to guess, the when your gauge says it's empty, that there's probably 6 gallons or so left in the tank. Maybe you need to have your fuel gauge calibrated, or make sure the arm on the sending unit is not hung up on somthing inside the tank, or bent, etc....just a thought.

I totally agree......and lets not forget factory 440's also came with as much as 1250 CFM ( six pack), and you did'nt have to race them! They were daily drivers! I own one. LOL!

I'm thinkin the 650 CFM is a little small for a big block. I'd be looking for an 850 CFM holley if it were me, or the 870 CFM street avanger is a nice all around carb, for your application. JMO.

did you open your trunk, and look at the driver side wheel house? If there's a large tube protruding up through the trunk floor,that has a cap on top, fasten'd to the wheel house, then your car had the tank with the 4 vent tubes on the side. if not then your car did not have it. Most 71 cars...

ok Mitch, Heres some more pic's you requested. Hopefully they show what you want to see. if not let me know, and I'll shoot a few more. I have this carb, next to the computer....LOL!

no problem! rock on !!

so it looks as thouigh you are missing about 4 peices.....The solinoid, the choke pull-off, the linkage for the pull-off, and the small peice that the choke rod connects to. It looks as if someone as put the arm that contacts the solinoid on wrong ( 180 degrees off) ...no big deal.

Ok, I just ran out to my shop, and took one of my carbs off the shelf...here's a correct ( #4934S) 1970 340 automatic Non-AC carb. that has the original solinoid.

yes, It looks as if someone had a manual choke set-up on it. I have a correct carb with the idle solinoid, I can snap some pic.s of when I get time, if it helps

I worked in chrysler dealerships for years back in the era, and thermoquads have a tendency to warp the plastic fuel bowls. Especially if the screws work loose. I'v replaced a lot of fuel bowls on these over the years. I remember it was a big problem with the lean-burn era cars, ( cordobas etc.)...

I'd trade you a eddy 600 cfm manual choke verson ( #1405 I belive), and adapter plate, for your thermoquad. PM me if interested

Great thanks! I had no luck searching the holley website.....

Hi, does anyone happen to have a chart that tells which color holley accelerator pump cam is (the plastic cam) the least aggresive to most aggresive? I currently have a green cam installed in the #1 hole and would like to try the next one, which is more aggressive. Just expermenting. I have...

it's not normal.........sounds like the needle and seat are leaking by, or the float is bad, and overfilling the fuel bowl. It's probably time for a carb rebuild.

oh.but you'd probably need an adapter? spacer to square bore instead od spread bore

if it were mine I'd go with a holley 670 street avenger, with electric choke....they run great! I have a 770 street avenger on my 71 duster 340 with a mildily built engine, and I'm very pleased with it.

any pictures?

You say your filter plugs up a lot?? with what, rust ?? If so I'd consider replacing the fuel tank. You should not have a filter plugging up as often as you say. You need to get to the source of the problem.
