Did the 67 GT350 with auto trans use the holley 715 or the Ford Autolite carb?

Both. It was supposed to have the Autolite carb like autos in the majority of 66 GT350's were meant to have but for some reason not clear at this time some still ended up with the 715 carb. The few auto 67 GT350 that received the 715 carb also would have a added bracket and throttle dashpot like the Autolite carb if original to the car.
Thanks for the info.
here is an original 715 that was on an early '67 Automatic (Black) car, the yellow arrow dash pot unit on the bracket Bob is referring to. (red call-outs are just original features)
Are the choke plate and choke plate shaft universal among the 9510 carburetors?
Seems they would be.
What does the red circle inside the port represent any difference from one 9510 to another?
Not sure what you are asking. 9510 is the base number for all Ford carburetors of any size be they 1 barrel, 2 barrel, 4 barrel etc of any year or brand.

Ok, Let me see if I can re-phrase, did
"4V carburetors" that were used on any Shelby big block or 428CJ,
4 barrel that is, share the same choke plate and shaft?
i.e., Holley list:
4174, 4168, 4129, 4279, 4280, 4511, 4456, etc,etc...
These List carbs, did they share the same choke plate and shaft?
I believe so since a Holley 2v is essentially 1/2 of a 4v.

Not talking about 2V's, look these list numbers up that I posted and you'll see they're all 4V's ;)
Let me phrase it this way, I have 1848, 1849, 1850, 4118, 3259, 4779, 4778, 4776, 3300, 3301, 6619, 4180, all use the same choke plate and choke plate rod.
I can't speak for all but I would think highly likely.
The only Holley 4v I can think of with a different choke is the street Dominator. I can't remember the list number now
Yea, may put a 4V on my 2V mustang with 4V adaptor plate :o JK ;)
Thanks SD
That would be the best money spent on upgrades for your car. A great performance addition for little money. Back in the day I converted many 2v to 4v applications and can say you will feel that upgrade . Good stuff
On early factory carbs there are 3 different choke flaps, 4 different rods, all shafts are dimensionally the same, but there are many distinguishing features.
I often show these comparisons on my AirFuelSpark page.
If you ever want pictures of all the differences of something, just ask and I'll collect the images.

OK ,I will ask please.
Drew, you don't take carbs out on the boat with you do you? :o
Don't forget your sun block. Gotta be pretty hot out on the water right now?
Just let everyone know that Drew done a superb job on my Holley 2V. The Mustang runs GREAT👍🏻
Thanks Drew😎
There is only so much uumph that a 350 cfm 2v can offer. A 600 cfm 4v will be a welcome addition to your ride. Drew does great work, most can attest to that.
This is a cruising Mustang. 2V is all I need. Would be no use for me to have 4 barrels cause I barely open the 2 barrels😆
This is the way my (late) Dad in Law wanted it and that's the way I'll keep it👍🏻
I drive it in his honor🇺🇸
+1 there are several and some are still available from Holley. Others are not so easy to find.

IF you are restoring a valuable carb accurately, then that is important. Functionally they are larely the same.
The early carbs use slotted head screw on the chokes, after some point, they are Phillips heads.
"Different but the same".
I think the choke flats are strait early then switch to bent shape around 1970 or so.
I think there are some choke rods with straight arms, then switch to a dog leg shape.

No,"same thing only different" ;D ;D
Um yes it is hot. Boat is running loads in the gulf.
My engineroom is 122 degrees at the moment.
Day 4 of 42.
Pictures below which detail some of the stuff
The second photo is a 1963 dated list 2919 with bent flap and cutout.
Bent choke plate. Bent plate with cutout, flat plate.
Choke rods:
Nearly straight, very bent, and one that needs cotter pins to retain
This is just Ford stuff, there are more variations with chevy stuff. More still when you get out of the 60's. Blah blah blah
Other fun photo
67 dated 3259-1 with later over the counter 3259-1
I did a highly detailed comparison on my afs page last month.
Dang, thanks for the info.

Catch me at home sometime and I can show better pics. This is just what is on my phone.
Most photos are on my laptop, at the shop I have a ton of the carbs around, seems a good idea to detail everything as they come in. Currently have 500 or so files on factory carbs. Trying to triple/quadruple verify them all.
Drew did these carbs for me and car runs great, feel so much more power, no hesitation at take off now.
Drew does excellent work. He doesn't just slop a kit in them. He caught several manufacturing issues and corrected the two different sized holes. The dual quads run night and day difference. I would highly recommend Drew to anyone.

Just received my 715 Tuesday. The car had always run rich, Drew figured out the problem and now it runs better than it ever did.
I am very happy with the rebuild.
