Hi I'm doing a 1973 Dodge Dart Full Kustom, with the 225ci Motor. I'm using a pair of Twin Side Draft Webers on a Custom Manifold. Also Split Headers from austraulla. Has anyone tried it yet. If so any Problems with it. I need to put it in Before I spend 3 to 4 Grand for my Paint Job. I also have a High Output distributator for it also. I Hope running TWO Mufflers I can Have a Good sound, But Not like a Chevy 6 Low Rider Sound. I really Haven't Heard a Slant 6 with Split Headers. If It sounds as Good as my 86 Fiero Gt V-6 I'll be Happy. It has about 235hp. I'm not sure what a 225ci Motor with a Stock Cam with 2x2bbrs Webers & 2 Mufflers will produce HP of?? The Webers are 2bbr Carbs. 36mm Webers. They are on a Edelbrock Manifold. Going to run an Electric Carter 72gpm Fuel Pump. Ron of Ron's retired Fiero Repair of Fontana, Ca.

I'm sure someone has done it, once you start thinking that you've come up with something unique, it just means you have to look harder back in time. The webers should be fine, people have run them before, and there is a triple weber carb system you can purchase out there also. Performance wise I would say it should be a 20-30 increase with the webers and exhaust from the bone stock engine. No doubt it will be cool, but for all out performance you'll have to tear into her a little more.

Yup, it's been done. The company (Pro Line Fuel) that used to offer the ready-packed kit are no longer in business, but the parts to put it together yourself are still on the market.

Careful with Australian headers, which are made for RHD cars. Our LHD cars have much less clearance on the manifold side of the engine, because that's where our steering box and shaft are. You may want to look at Dutra Duals, which have the added bonus of not needing costly shipping from Australia.

Too many people who were born on third base actually believe they've hit a triple.

The increase isn't much (about the same as bolting on the 4 barrel and having at it, but with other headaches... like synchronizing the carbs and dealing with front/back fuel issues, and having to order your carb jets and parts, instead of getting standard parts over the counter...)... You could also look up 66Dart's rig as he's done this and it moves, but the rear carb always has fuel boiling issues, and I think going to dual progressive carbs over dual standard carbs would help mileage and 'control' much better, and a set of phenolic spacers would keep the carbs from cooking over the heat stove area...

-D.Idiot

I dont know if there is room for spacers on this setup with Webers. I have the duel Weber setup but have not installed it yet, but when I measure for clearance it looks very tight on clearing the hood. Until I install it I just cant say for sure but it appears that even the air cleaner used will have to be payed close attention to.


The clearance problem has pushed me into getting the intake welded so the Webers can be bolted straight down instead of using adaptors. Its very close to being able to just drill the intake and bolting the Webers straight down but its not close enough because of the way the base of the Webers are made will cause vacuum leaks if it does not have enough surface area to cover the complete bottom of the carb.

If I was to use adaptors, or spacers it measures out that I would then have to run the real then air cleaners and this will cause problems in the running and tuning of the carbs because the air cleaner top is just to close to the bowl vents in the carbs. This will cause all kinds of tuning problems and makes the carbs very inconsistant. Plus they are restricted flow at WOT.

I have the Pro Line Fuel setup that SlantSixDan mentioned. I've had it on my nearly stock Volare for a few years now. I have never changed jets, or fine tuned it that much, but it's been a reliable setup, and driveability is good.

What other carb/intake setups had you run before installing the Pro-Line Weber setup ? How did it compair on power , both bottom and top end ?


If I am remembering right they didnt use the 32/36 carbs, there may have been something like a 30/30 or something else. Do you know what carb series & size they are ?



With the setup being a supplied kit for the slant it should not have needed much on tuning, but chances are its setup a little rich and tuning could gain you some power and economy. OFcourse being two carbs = double the amount of jets just to try, so that could get into some money quick. AT todays gas prices it could be worth it though.



Jess

Actually that's why the guy went out of business, he assembled the components and dialed them in for BF Idaho... so when guys near sea level got them they were rich as all get out and it cost a bundle of $$$ for a new set of venturies and jets to set it straight... (In Doc's case, he was going over the pass and it leaned out and died, if I recall his early tuning troubles...)

Another problem with the setup was the carb were non-progressive... so a stab at the acc. pedal was like opening all 4 bores on a 600 cfm Holley... you got pressure drop, lack of good signal... each build being different, a 'general' setup wasn't broadband enough... it works OK on Wes's 'stock' setup, but was a bit tempermental on a 'better than stock' setup...

Once you get a set of carbs that you can get parts in cheap and sort the problems out, it'd be a fun setup... I had much more fun sorting through getting a hyperpak to run on the street than I did trying to fish for problems on one of those things (and the original owner didn't like any 'feedback'...)

-D.Idiot

D.I. pretty much hit the nail on the head. This setup has worked fine for cruisng, daily driving, but there has always been a bog under hard acceleration. This hasn't been an issue for me, since I'm not racing. My car idles smooth with this setup, and it looks cool, but for acceleration, it leaves something to be desired. Tuning would help I'm sure, but I'd rather go to a simpler setup, which I probably will this Summer.

Oh yeah, I'm not sure which Weber carbs these are. The first two digits look like "36", then "DV" I think.

Snap a picture of your dual weber carb setup?

If possible clean and rub a black marker over the "36....." lightly to see identification easier and report back?

Cheers, Wizard

The Dual Weber setup on the Dart has worked well with the engine build that D.I. and I performed back in 2004. As D.I. stated, there is an occasional problem with heat soak on the back carb (near firewall) in the heat of the summer. Overall, the setup works well and I can easily cruise or jump on it with quick response. I have fine-tuned (to the best of my ability !) the carbs with different jets and venturies to achieve good engine performance and adequate mileage. I am achieving approx. 16 mpg city and 18 highway. Oxygen sensors are installed under each carb and this gives me the ability to keep and eye on general carb operation. The Weber carbs are model DCNVH36.

Hi

I am doing one now based on stuff done in the sixties over here with twin 36DCD7's - they are progressive and very tunable

It's never junk, it's just a part you're not currently using

Just say I own a few Mopars

That is one good looking car 66Dart. You meantioned having O2 sensors. Just wandering what A/F ratio's you have at a cruise with that setup ?


One think I have noticed with WideBand O2 setup is when at WOT and you go to shift that almost every setup I have tried would go lean when I shift. When the RPM's recover and as the RPM climbs it levels back out to the A/F ratio. Does this system do like with you ?



Jess

Hello, hey this is Chris from, the now dead, Pro Line Fuel.

I just got curious to see if anyone was still running the dual setup and found this thread. Good to see so many familiar names here.

As for the issues some people had with the setup, I apologize... it certainly did have a problem at WOT. with the synchronis carbs, it was jsut too much of an air hit at once....and it was hard to find the right jet/ venturi to give a guy something that would behave correctly in all instances.

As for going out of business, it had nothing to do with this set-up.
I was dealing in more than just the dual weber kit, Jeep kits, MGs all that junk...
It had to do with Weber going on strike, and supply of carbs dried up fast and prices went through the roof.

Anyway, I hope you all are doing well... good to see a few of the set-ups are still there. Hey it was a Valiant effort!
