Twin Carby Manifold....Dodge

HI All
I am restoring a 1960 A3-59D Dodge Truck.
I purchased a part restored project.
I have never started the motor 'Dulux Overhaul' but was told by the seller that it was a goer. Have factored in a rebuild if necessary.
Am thinking of the posibility of fitting Twin carbies and extractors to it.
For the 'purists" out there I have seen a twin carby manifold in a Canadian Dodge Parts Manual.

SO...........Has anyone got one and how much????

Check out my Project on Restoration Chat.

Motor and manifold as/is.

No eBay APP ID and/or Cert ID defined in Kunena configurationSpeed equipmement such as the Twin carbie manifolds are quite rare these days for the Dodge engine but if you look around various places you may be lucky in getting one. Here in OZ they were mainly used on Marine engines in speed boats during the 1950's (both the inlet and exhaust manifolds were cast in alloy (the exhaust manifold was water cooled for obvious reasons!) I have seen a few marine engines come up on Fbay here in OZ so they are still around despite being fairly well obsolete for any boat these days.

I have both the inlet and exhaust manifold of these to suit a Dodge "Kew" engine (25 inches long). (Sorry NOT for sale! :'()

In the US twin carby manifolds have also been used as speed equipment (and dress up items) as well as finned alloy heads which look awesome and highly sought after. Most of these were made by 'Edmunds' and 'Fenton'. Good luck finding these too! Try Fbay US or Hemmings Motor News and I hope you have deep pockets!! :

Here is one: (note 230 engine - will it fit????).


Mopar And don't you forget it!

I have this set up I don't know what its off and the inlet manifold is broken and half it and exhaust manifold are missing but it may give you something to start on

HI Slantie and Elgindale

Thanks for your assistance Slantie..........I first heard of the Twin Carbie set-up off a Guy who had a complete motor out of a speedboat sitting around for so long he ended up dumping it at the Tip.........what a waste.

For Elgindale.......from phots's Ive seen yours mighten be off a Dodge/Fargo etc..........carbies look too close to each other. Could you please take another photo from the ports side with a ruler in view so I can compare to my engine.

Thanks

I have heard of Twin Carby Manifold for the Inter petrol engines also. But as I understand it was done generally on army vehicles not so much for Civilian vehicles.

I think the idea was that one standard carby across the fleet and when you have a bigger engines you put two on it!

Not aware of it being done to get more power or speed. (that is increase the designed output of the engine) Just a way of ensuring that the power plant is fed adequate fuel etc.

By the same token do you really want to go through twice the fuel? For example my AB Inter engine which is just the little 240 engine with overhead valve etc and single carby with extractors. So probably similar to your engine (except the valves so might be higher compression ratio?). Will use about 20Litres of petrol per 100km's with a small load. Empty it might go down to 15+ or so (depending on driving style and road of course). The worst I ever had was running near max GVM and running large hills at speed I hit 27 l/100km! So hate to think what a double carby would use! Especially looking at the current price of petrol! :'(

HI JBlair

Thanks for your insight. I think that put paid to the Twin Carby idea. Will get a set of extractors.

ummm ... two carbies don't mean double fuel. Ya gotta change the jets to suit.
Often a multi carb setup can give better fuel consumption along with more power. It's the extra air flow that counts.

Case in point, my old 180B SSS datto. Had 1.8 litre engine and twin SU carbs. While I was getting them rebuilt, I fitted a single carb from a standard 180B. Used the same fuel as the SUs before rebuild. (around 32 mpg) When the SUs went back on we consistently got better than 35.

Also had a X-flo falcon six in a XA that ran 26 - 28 mpg with triples ... about the same as my with stock weber.

Offenhauser in the states do a manifold for it. They do a lot of manifolds for old stuff evan a HYPERPACK for a slant :)6.
