Fiat Abarth or something... nothing less sure

Well, I would agree that one carb would probably be too small considering that the 170 slant six is something like 3.0 liters. However, running two of those carbs might actually work out okay. You would have to create some sort of throttle and kickdown linkage, but that would be the hardest part (after making the intake manifold). I don't know much about Weber carbs, or Fiats, or dual carb setups, but it sounds like it might work. The key factor here is determining what airflow each carburetor is rated at. The BBD flowed 280 CFM, the Holley 1920 flows around 200 (I think) As long as the combined airflow of the carbs is equal to or greater than that of the stock carb you should be able to make it work.

What would be most helpful is if you could post the model of Weber carb that you are trying to use and give some specifications such as one or two barrels, staged or synchronous opening throttle, CFM rating, etc...

I have seen some wierd weber setups, from the factory.
Like the 1.5l talbot, with a twin 40mm weber downdraft...
I am pretty sure it would flow enough, but tuning it to work as it should on a slant may be interesting...

hmm and i was looking for a project to do that was metal related (welding class) at least it needs cutting....hm maybe i should try it for the hell of it i got 2 extra 1bbl intakes laying around. I also have a cracked ex manifold....can i weld it and make it usable(i probably wont but for something to do) can i tig weld it?

One thing i just couldn't figure : is the stock intake manifold such a good design? With those inequal runners all connected together, the pulses are always interfering with each other, right? For minimal interferences a 2*1bl. would be better, but does it need any plenum volume? What size?

Blue195,

The first page of this post would be much easier to read if you edited your picture down to a width of 420 pixels wide.

The way I have done it in the past is to take my 240 volt arc welder, set it on max, use a grinder to clean the manifold areas to be welded, then just laid on a big fat slow wled. The metal heats up quick and seems to bond well. Of course, I have never yet run the manifolds I repaired/fabricaed this way....

I was bored today and made a big mess in the garage with a cutting torch, grinders and such. Still need to finish grinding the steel plate that will be welded to the cut open 1bbl intake, but then it's welding time.

I wonder, could you just smear JB Weld on it and bolt it down (with new holes, of course)?

Love me some a' dat JB Weld... fixed me a cracked cylinder wall in Don Garlits Swamp Rat XXXIV back in '61 wit it! LOL

I think I would use some sealant instead of JB weld, just to help seal any potential leaks, The bolts should be enough to hold it in place.

Excuse me, does this smell like chloroform to you?

I did a homemade "torker" style 4 bbl manifold for a 273, back in the '70's. Was based on a stock 273 single plane 2 bbl manifold. Hogged out the top of the manifold, and "glued" on a open carb spacer (2" I think), with Decon Plastic Steel. It worked great. I still have it on the shelf. Any one want to buy it?

Well, I don't roll like that. I can weld it so I will weld it.

That works. Your setup just got me to thinking about the spare 1bbl intake I have, but I can't weld (at least no on cast iron).

So, will you be able to use the 1bbl throttle linkage on this, since it's turned 90 degrees to the Super Six setup?
