Weber DCNF carbs

[Sonus]

I am considering replacing the two SU HD6 carbs on my Daimler 2.5 V8 with four Weber DCNF 40s. But before I shell out a redicioulous amount of my hard earned I need to know if four DCNFs will actually fit the rather small Daimler V8. The port spacing is 95mm even between the four inlet ports.

So does anyone have a DCNF they can measure or know the following measurments;

1. Overall height from base to top of carb without any extension/trumpets?
2. Overall width
3. Overall length
4. Length from center bore to both front and backside.

And the reason for chosing the DCNFs is that they supposedly are the smallest dual barrel carbs. Smaller than both the IDF and Dellorto DRLA. Oh and the fit across the V instead of along it.

If you have access to some scaleable software, approximating dimensions should be fairly straightforward. That's a Maserati V6 from a Citroen SM. Import the pic into a drawing, scale, dimension, and go. If you can't do it, I can help.

It sounds like a worthwhile adventure, but where are you getting a manifold from?

Best,

Thanks

Top pic is as Ephemera says DCOE/IDF. DCNF is Square 48x96mm as used by Jenvey for the TB - http://www.jenvey.co.uk/home/twin-throttle-bodies/...

I will try to scale the picture, but do the SM use 36/40/42 DNCFs?

Thanks to Slow M and Ephemera I have bben able to make this rendering of a DCNF40 carb ontop of a Daimler V8. I also found a side sectional drawing and have indicated the top of the DCNF in comparrison to the original SU.

In the side view you can also see that the rearmost inlet will place the rearmost carb where the distributor is. The dynamo will have to be changed or moved aswell.

Probably have to make something from aluminum, but have toyed with using carbon fibre.

I have had a look at Weber IDF40s tonight and they look like they can be stacked closer, but Idon't know if they can be mounted across the V8? They are also a bit bigger physically I believe.

I know that the engine is commonly used with Weber IDF40s for racing. But IDFs are quite a bit bigger than IDFs I believe. Engine has been ported and a 270 cam fitted. The original manifold is strangeling the engine somewhat because it is rather convulted.

That's impressive. I'd love to know how to use 3d software properly. I've tried simpler programs like Sketch up etc. but have had no luck. So I have ended up trying to find parts that are pre-made that can be cobbled together to make what I need. However if you really wouldn't mind I might ask for some help when I have gotten a bit further in my planning.

Just received a pair of 40DCNFs from a MG Maestro I won on Ebay. Not quite correct as the idle set screws aren't angled like the 13-versions so will be tricky to get at when the carbs are placed after one another. Slight issue is that the center to center dimension for the throats will need to be 115-120mm and the port spacing on the heads is 95mm. Also need to somehow step the throats down from 40mm to 29mm at the heads.
