Post subject:  Weber Progressive on a 225
I have my '72 Scamp at school right now, I fixed the carb (thanks Slantzilla!) and then found out it had a compression problem, which ended up being a bent valve.

I was thinking of using my Weber Progressive in the near future...

I have heard of adapter plates for the one barrel intake.
Where can I get one of those?

If not, what would you guys recommend? A Super Six intake manifold?

What about linkage? Thanks for any help! :D

HERE'S an article about using the Holley/Weber on a Slant Six, which might be of some use to you. He used a Clifford manifold with different mounting plates, though.
The one-barrel manifold would be restrictive as it comes, negating the advantage of the Weber. I'd look at either a Super Six manifold with an adapter, or modify the one-barrel manifold to fit the carburetor.

Hi

Due to the Airflow requirements A 38DGAV or 38DGAS =- V is is staged, S is Synchronous Nothing smaller I f using Dual Carbs the 36 DCD is an option

Problem is you need a Weber guy or be one your self to get them spot on - everything, or nearly everything can be replaced on these carbs for tune ability

Good luck

I have a progressive 2bbl Weber and 2bbl iron intake if interested.

I have to look and see what model #, I know it's says Holley and is a remake of a Weber though.

Then this is not weber, it's holley 5200 (early ford) or 5220 (chrysler). Bit small still. This is what guy recommands for DGAV 38 as staged means you can have MPG and have power at top end.

Weber 32/36 is about the max on 2.8L size. On 225 (3.7L, you are undercarbureting it.

Getting the holley version of weber dual barrel carb is ill-advised as rebuild kit is much expensive and quirky than geniune weber. Used low miles webers are plentiful on ebay, if the throttle bushing is worn, it is easily done with a good carb repair shop for not very much. Weber rebuild kits are not that expensive (around 25-40, vs 60 to shockingly 80 for grabage brand of rebuild kit for those 5220 carbs!) Plus you can get jets and vitally the idle jets that you can change as needed where holley you cannot do.

I dumped my holley 5220 and put in Weber DFAV 32/36, worth the trouble.

Cheers, Wizard

Sweet. Looks like I need a new intake manifold.
And yeah, I plan on sticking with the Weber DFAV 32/36 that I have.
Thanks a lot for the tips guys! I'll stay away from the Holley... :D

PS: So I would have to re-adjust the Weber to work with a 225 right? Where do you guys suggest me getting a kit for it? It would need to be re/jetted too, right? Thanks again SL6!!!! :D

Some of the Jeep forums mention this carb; you might want to check them out. I had one on my wife's Horizon and I gota tell ya, it's a very amazing carburetor! But you have to set them up, and it's a PITA. Once set, you can forget it. It'll run fine for years without touching it.

Nice, I'm in the process of getting a super six manifold and linkage, hopefully I can get this carb to work. I'll keep you guys posted, thanks and happy holidays! :D

Is your set up using the super six manifold and linkage?
It is a progressive, split throttle plate?

Thanks,

This is kinda oxymoronic on your part isn't it? Where do you base your facts that a 32/36 is to small for a /6? You'd be very hard fetched to convince me that it is. Prove it to me! Thanks

Take a look here: Weber data

Even with the larger chokes, the flow maxes out in the 245 cfm range.

For a stock 170 that should be adequate, anything more it's under carbureted.

So am I better off selling the Weber and getting a Carter then? :?:

You may also want to look at the possibility of a Motorcraft 2100/2150 (Ford carburetor); see this thread and this one

i put a 32/36 DGEV on my sons 86 D100 with stock engine (less lean burn) and exhaust, so far have put a bigger primary idle jet in it which is the first step in tuning these, i believe the next step is the main jet. used a offy 4 barrel intake and adapter plate and 2 of the heat insulator spacer plates to keep the carb from getting too hot. his truck runs great. good drivability, great milage 20+ mpg. the 38 would give more power, but the 32/36 works just fine. andy.

I had a progressive weber on my 200 ford inline 6. It ran fine until you were over 60 mph and accelerated then you could hear detonation. Lack of fuel.

I've seen a set-up of twin progressive webers on a slant using the 2x1 intake. Always thought that was awesome. Probably nice performance too.
