Adapting HW5200 2bbl to Aussie 2bbl intake

[Vin Man]

Anyone sell and adapter that will allow me to use the HW5200 with my stock aussie head? The pattern on the Aussie head is the small 2 bbl.
I can get a Mr. Gasket 1937 that adapts the Aussie head to a Autolite or Holley large 2 bbl such as a 2100. However, the pattern on the HW5200 is smaller than the Holley/Autolite, yet bigger than the stock pattern on the intake.

I tried to call Langdon Stovebolt which is where I purchased the carb, but they are on vacation until mid March.

Unfortunately, even classicinlines doesn't seem to sell this adapter. Mike has something similar to the Mr. Gasket adapter.

Let me know what you have or where to get one. Thanks.

I designed and had built an adaptor to install the 2100. If you’re interested I will ask the machinist what he would charge. The shipping would be from the Seattle, Wa. area. Check out the link below.

After the plate is installed, the manifold can be marked and ground to open up the bores. The nice thing is about this change, the smaller carb can still be used later.

That's a nice looking adapter you have there Ric. As you stated, it would be used to put a 2100 on the car. The Mr. Gasket 1937 will do the same thing. They are about $20 from Pep Boys here in the valley. It might not have the exact bore opening like the one you have, but it would be close enough for me.

My problem is I need to adapt a HW5200. The more I study this, the more I don't think it can be done.

The bolt pattern on the head is 3 1/4 by 1 7/8. The bolt pattern on the HW5200 is close to 3 3/4 by 2. I don't think there is enough room to both bolt to the intake, and then have mounting holes for the carb. I think some of the locations would overlap.

I was looking at a document online today that shows 2 different bolt patterns for the Rochester two barrell. I think what I've trying to do is mount a larger Rochester 2 barrel to the smaller intank.

See page 74 of this pdf file. Look at the last column.

I could have swore that I had made one or at least designed one for the 5200 DFV foot print as well. I will have to look for the drawing.

If you have one, I need it. Let me know. Thanks.

What about a 2 piece adapter? The lower one would adapt the original manifold bolt pattern to a pattern that was significantly larger than either the pattern on the manifold or the pattern on the carb. You'd use something like Allen-head screws that were recessed into the top of the lower adapter plate to attach it to the manifold so you'd have a flat top surface on the lower plate to which you'd then attach the upper plate. The upper adapter plate would mount to the lower plate and provide the proper mounting points for the carb, and perhaps attachment points for a throttle cable and such.

The one real problem I see with this approach is that you could end up with an adapter assembly that was pretty darn thick. That might create hood clearance problems.

Great idea! But I also believe you have nailed the issue on the head - or should I say hood? I already have barely enough room for a low clearance air cleaner.

There is a great picture on the classic inlines website of a car with this setup, but I can't see the adapter in the picture. Mike didn't have any info on the car itself so I'm hoping someone here has done this already.

Here is the pic I'm refering to:

Try the site below for an adaptor to fit your need. I came across this looking for dimension for the different gaskets. Take a look at 2086, this may work for you.

Good luck, Ric.

Thanks Ric. The TransDapt 2086 that you suggested is the same as a Mr. Gasket 1937. I did call Transdapt and ask if they made anything that would work for my application and they do not.

Appreciate the effort though!

They might have what I need. Unfortuantely, their website is void of any details.

I'm thinking I need something like what is pictured here from the redlineauto website:

http://www.redlineauto.com.au/products/product/10-112?category=GQGRYXUE

However, since there are no specifics other than "Adaptor - Weber D/Draught 2BBL", I'm not sure if it will be what I need.

I'll call them when they open.

Redline has the adapter I need. It is their part number 10-2216. The carb side of the adapter is 92 mm x 45 mm and the intake side of the adapter is 83 mm x 47mm

If I did the cost conversion right, it will cost me about $60 to get it here from Australia.

I'm still trying to find an equivalent here in the states, but it doesn't look good. The closest thing I have found is the Transdapt 2107. It has the right pattern for the carb, but the intake side is too small by 3mm in each direction. I'm thinking I can buy this adapter, and then slot the holes a little and get it to fit. It would only cost me about $35US to buy this adapter. Pep Boys sells it for $31.99 and Checker Auto will meet that price and have it here in 2 days. Only other concern is that this adapter is 1 3/4 inches in height which could lead to hood clearance issues.

With a little more web surfing, I may have found another adapter out of california. There is a company called JAM engineering that sell a 2 piece adapter that I believe will work.

http://www.jameng.com/products/index.phtml?section=13

99004.551: Jeep two piece carb adapter.
Adapts DGV series Weber carbs to some Jeeps. Manifold studs measure 3.250" x 1.890" (83mm x 48mm) center to center
Price is $33 plus s/h

I'll call tomorrow to see if they are still in business.

That's the same 2 piece adapter that I had on my CJ-7 when I was running my EMPI 32/36. In fact, I still have it. It's at my dad's house with my Falcon. If things don't work out with that company, let me know.

Yep - it's advertised for a Jeep, but the pattern is the same. I have a CJ5 so I know it will work.

Wish I would have talked to you before I ordered it. I'm sure someone else here on the board could use it.

Ah, I see what they did. Here is an image of the thing.

The lower plate (on the left in this image) attaches to the manifold using the 4 recessed corner holes, then the upper plate (on the right in this image) attaches to the lower plate using the 4 holes laid out in a diamond pattern, then the carb attaches to the upper plate using the 4 holes on the upper plate that are in the corners.

It's a clever design, really. The use of the diamond pattern for the screws holding the two plates together allows the adapter to be smaller than the design I had envisioned because it keeps them within the "footprint" of the carb itself. The result is a tidier looking carb mount.

Furthermore the fact that it is for a fairly common application (a Jeep) means they can afford to develop a way to produce it using a simple pair of castings rather than custom making them out of billet aluminum, and that greatly reduces the cost when you're making them in large quantities.

Brilliant!



By the way, if the thickness of the adapter creates hood clearance problems, then you could look at an additional adapter they show further down the page which enables you to use a side-draft Weber DCOE carb instead.

This one:

KC 172: DCOE to DGV adapter.
Lynx adapter adapts the DCOE series Weber carb to the DGV series Weber manifold flange.

Unfortunately that's not available at this time, but ...

Yes, I was also impressed with the 2 plate design. However, between the 2 plates and that fiber spacer, I'm concerned about hood clearance. They also sell the low clearance air cleaner (which I still need), but don't want to purchase until I install and see how much room I have available for the cleaner itself.

On top of everything, I also have a Jeep CJ5 so I know this adapter won't go to waste :roll:

I deal with them all the time so they should look after you.

Ken was very helpful. He sent me an email today with more info, however since I found something locally from California, I let him know I wouldn't be ordering one.

Thanks again for the lead.
