Yea, two 97's are overkill, but two carbs (81's) are cooler than one. It'll give you as much additional HP as painting it red. In fact, three carbs is even cooler yet. I think secrets of speed sell a progressive linkage that lets you cruise on one and kicks the other(s) in when you accelerate.

That's what I was thinking too, a progressive seems like the better of both worlds, as long as the manifold design doesn't affect it

Some have said that, Red and Green, is fine at Christmas.
But, Orange is all year long.
More farm boy stuff.. Jeff
Yes I had one of those also. A WD it was a tuff one.
Along with 4 JDs 720, A, 2010, and a H. They all had there place on our Farm.
As far as two carbs on a stock engine it will probably be more trouble than it is worth.
Any of the two barrels you talked about should work fine for one carb.

Where do these Stromberg carbies you guys are talking about come from?
I run an Australian Stomberg but it is different from the ones I see pictured.

Here's a point to consider: I ran a pair of original 97's that were rebuilt by the gurus who sometimes post here. Performance sucked. Bit the bullet and installed a pair on the "new" English 97's and great performance. So, the question is are the new 97's better than the the original?
For the record, switched from a pair of 97's to the Weber 32/36 because it's easier to tune for different attitudes.

My engine builder reccommended the Stromberg 97 over the Weber, so I bought the new English 97 and sold my Webers. Now you have both sides.

You should buy Jim Brierley's book. He's the guru of hot 4 Bangers. I couldn't wait get it in the mail so I drove down to Temecula to pick it up. By the way, is that Alviso in the Bay Area?

Now I'm really confused - English Stromberg as well.
What cars were the 97's fitted to? (Assuming they were)
The Australian Strombergs I use have exactly the same mounting flange, bore diameter and bolt spacing as the original Model A Carbs, only they are downdraft. The Holden engine they came from, required a little more air at max revs than a Model A at 3,000 rpm so they are ideal.

I think that the "English" Strombergs are actually US models, just that manufacturing was moved from the US to the UK. I don't have access to mine at the present, but I believe that it is molded into the casting the original US address of Stromberg. Parts & pieces are suppose to be interchangeable with the original Strombergs.
As far as their original usage, my understanding is that many of the early Ford v8 engines came equipped with them.

Progressive 2-barrel. More than likely, same as yours.

Is my 29 Tudor green close enough to be JD green?
I call it puke green, but at least the metal under the paint is very nice.
BTW, if you ever get a chance to ride in a Ford Tri Motor, go for it.

Not even close! One of the guys in our club has 31 Tudor that is genuine JD Green, even has the yellow wheels to complete the illusion. He bought it from someone in the farm country of the midwest and decided to leave it that way.
As far as a Tri-Motor, closest I got was to step into the cabin of one at an air show at Boeing Field in Seattle years ago. Did get to see it fly, but that's all. As a kid, I was totally enamored with that airplane.

Orange? You mean the tractors with the turkey roost?
We had one that two 97's on it that was a little much. It ran much better with one
97, but we wanted it to look cool. We plugged one side of each carburetor and it ran
it with just two of the barrels working.
Looked cool and ran great.
We did this on a flathead V-8 with a 4x2 manifold that everyone said would never work,
they were amazed at how well it ran, but didn't know it was running only on 4 holes instead of 8.
