I think you needed to look for a 32-36 Dgev 336b or 38-38.

If you are asking if it will fit the adapters that are sold for these engines, then yes. Otherwise, any Weber carb could be made to fit. DGAV, DGEV, DGS, DFV, and Holley 5200s - all have the same bolt patterns.

I prefer the DFV or the Holley 5200. The primary throttle plate is on the left hand side of the carb instead of the right. This position makes the adaptation of the throttle rod to carb much easier.
As far as using a 32/36 the 38 it depends on the use. The 32/36 will provide the additional economy if you want it.
Have fun, Ric.

what are the differences between these DGAV, DGEV, DGS, DFV?
Throttle size governs numbers. First primary, second= secondary.
Most venturis are the call size for the throttles, less 14%.
A= water operated choke, E= electric. S = synchronised (opening at the same rate both throttles).
32/36 and 38's share a lot of the architecture. They are all related. The 32/36 is a staged opening version, the 38 is synchronized (opening at the same time). You can make a 32/36 flow almost as well as the 38. 93 mm x 46.5 mm bolt spacing
DFV's are the big Euro 40 mm 2-bbl, rather rare, synchronized. 93mm x 46.5 mm bolt spacing
DMTL are 2-bbl Euro Ford 2000 OHC 93 mm x 46.5 mm bolt
ADAS, 2-bbl French Chrysler C180/Centura, both staged 93 mm x 46.5 mm bolt
ADM, 2-bbl Euro FIAT 131/132 in 32 mm, Aussie Ford Falcon in 34 mm, both staged, 93mm x 46.5 mm bolt
DCNF, 2-bbl pre 1986 Simca, Ferrari, Matra, Maserati. Syncronized. 85 mm x 52 mm, Bore Center-to-Center 1.889 " (48 mm), like the Holley and Rochester 2-bbl
DCO/DCOE are side draft 2-bbl , Bore Center-to-Center 3.54" (90 mm), four bolt with 15 degree slew, at 90 mm spacings.
IDA down draft, Bore Center-to-Center 4.72" (120mm)
IDF drown draft, Bore Center-to-Center 3.54" (90 mm), really a down draft DCOE
IDF 3C, 3 choke, 94 mm bore centre to centre spacing
I don't speak Italian, but I'm sure it makes sense to them!

For American market, with as little hassle, you can't go past the DGAV, DGEV, DGS. The Holley Weber 5200 version is better if you can get one cheap, but a new Weber 32/36 DGS or 38DGAV, DGEV is going to be an easy swap. Then the bigger Holley 2300, Motor craft 2150, Autolite 2100 2-bbls are better in the higher performance area.
In Australia, where detachable manifold 2V's and cross flows predominate, the ADM 34 is the best eccono and sub 175 hp carb around. It was raided for the Aussies by Borg Warner, who had access to Fiat and Chryslers un-used carburettor inventory. It has a return line, and gets over 30 US mpg in a 3000 pound 80's Falcon. Then the next step up is Holley 2300, Motor craft 2150, Autolite 2100 2-bbls, 4-bbl Holleys, and then DCOE 45's on a Lynx or Redline or other intake.
The ultimate has to be what the Argentines do...a brace of three Weber IDF's.
The passion of a little round Falcon compact 221 hauling the revs with these, unmatchable at any price!

so THIS CARB will get me around 30mph?
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2484794967
what do you think? is this an easy econo swap? is the linkage on correct side and everythinG?
this is ofcourse assuming I get the 1v to 2v adaptor plate....and an air cleaner

Yes it will, maybe more!
The stock auto with air conditioning 4.1 XE.
Did well over Imperial 22 mpg on average in a 3600 pound car, on chip seal roads. In America, your roads are often smoother asphalt or concrete, and the US mpg figure is about 25% better. Chip seals consume up to 10% more power.
The 3.3 XE can do 25 to 27 mpg Imperial on average with a 5-speed and 2910 pounds. The best fuel consumption can go over 33 mpg if you go easy.
Aside from the locked in idle fuel mixtures, the 3.3 and 4.1 carb are the same.
The only issue is that you MUST use a return line, and the Aussie fuel pump. Addo was saying the lever differs slightly due to the lever arm and cast in boss, which alters the total stroke, and therefore the peak fuel delivery. This is a feature very important with Webers, as the stock Carter fuel pump delivers over 6 psi, and the ADM will leak at that pressure. There is a 50 thou bleedback line, which lowers the float level and pressure for much better fuel economy.

on a final note...where would that return fuel line go to?...and I assume the perfomance is still aceptable with this carb...its not an econo slow carb is it?

right? wouldnt it be crazy if basically all we had to do to get 10 more mph is call on our austalian brothers....
that would about double my gas milage. I am at 14-15
I had a conversation with Addo...who said the 3.3 is better than the 4.1 here...less gas being shoved thru
(i think thats what he said)
so I gues sthe 4.1 is good for a mod application...
I need a smaller one...I think
plus, he said a cliford adaptor is needed...because of orientation...

I don't know my mileage yet (not road worthy) but I can imagine it won't be all that great. Currently my YF is running too rich. And there isn't much I can do to correct this problem - except a carburetor swap!

I'am not running the Holley 5200 any more as I have upgraded to a Holley 600 CFM 4V for my Aussie headed six, but when I was running the Holley 5200 I was getting 28 mpg and still driving it as hard as I wanted! Stoveboltengineco.com sells the Holley 5200 for about $75.00 for a rebuilt new rebuilt carb. Quite easy to adapt to our sixes.. Good Luck!

i have seen that whole thing about the 5200 and adaptor. I guess I wanted to do something different...
so answer me this Mustangeroo...did you have to fab a accelrator rod etc? or did it hook right up?
and what were you getting befor ethe 5200? MPG wise...do you remember?

I can tell you as far as making the 32/36 work with your stock accelerator rod, you will have to fabricate a few small aluminum stock pieces in order for it to work. Do a search on TheDude's setup for his 5200. His adaptation looks pretty straight forward. He answered all my questions I had as far as this conversion is concerned. Very helpful!

chazthephoenix,
On your 1968 Mustang none of these carbs will bolt right up to your existing linkage without some changes, or a complete replacement of the linkage. IIRC my milage was 17-18 mpg before using the Holley 5200.

Thank you Sir!
we have proved the point that doing a 2bbl conversion will gain approx 10pmg...with a little linkage work
Thats why I asked you....you have done it
so to everyone out there...do the conversion, save some oil!!
