Besides the Holley 2300 series carbs,what is another big 2bbl that will work? Im trying to get my junk together on a budget,and just had all my carbs stolen. How about the 2bbl that came on 360's/383's? Anyone try one?I need something bigger than the BBD/2280.

The build-
1987 D100
225
833 od
8 1/4 with 3.55's may go with 4.1's in the future
Rebuilt head with stock size valves,cut for 9-9.5 to1 comp 3 angle valve job,and some mild porting.
Solid lifter swap with the erson 270 on a 108 lobe center
HEI
Hooker super comp truck header,with single 2.5" exhaust.
Super six intake

I've heard the Weber38/38 is good. I have a 32/36, and I wouldn't recommend it as "big".

I think the 38/38 is only about 300 cfm if I remember right. Webers are great carbs though,thank you for the suggestion!

Assuming you have a stack of adapters to make them fit, and the engine is stout enough to use them, and the idle circuit isn't too rich, etc:

Carter BBD off a Big Block (even 413 powered dump trucks got these)
Stromberg off a early-mid 60's 361-413
Holley 2210 or 2245 off 360's and big blocks (not a real fan of the 2245).
Autolite Carbs off the bigger engines

Is the mounting different on the 2100? Thats what I am asking,what will bolt up and work. A member has offered me a 2300,so Im going that route. It would be interesting to try some of these other carbs though...Thanks for the info Rob.

The fastest 2 bbl I tried was a Stromberg off a mid 60's 318. It was awsome. But, it yielded only 15 mpg on a car that was routinely giving me 18-20 at the time, and I felt it was not something I wanted to stick with. The engine felt like a V-8 with that stromberg. The bolt pattern was the same as the BBD. It was a direct bolt on the factory super six manifold. .

Was the mileage drop due to using the new found power more often? Did you do a plug reading? Was it running rich?

Rochester 2GV? They were used on the 318. I believe they are around 300cfm....? A bit more than a BBD's 240cfm. Apparently there are even 'Rochester 2G' large bore 500cfm, some are marine carbs.

The 2vg was also used on the 'economy' Pontiac v-8 of the late 50's and early sixties. The drop in MPGs with the stromberg was due to more fuel for sure. I did not do a plug reading. I do not think it was running rich. It ran too well for that. It was just bigger. More air and more fuel. And yes more careful driving might have improved the mileage. But, I really liked the BBD. So, I went back to that.

That's pretty amazing economy. MIne was local driving. Maybe it would have done better on the road.

Best it ever got was 25-26 with the 1bbl. And 65mph tops.

My old Duster with a 225 did that well routinely with an economiser carb, and an automatic tranny. Best ever was 27 MPG on a trip to upstate New York in 1982. I took it because it got better gas mileage than my Toyota Carolla, (old RWD version), and had a bigger gas tank.

The only real mod was an MSD-6 ignition. I kind of think the economiser and MSD were the real magic combo. Plus, as you pointed out, the aerodynamics of a Duster are just way superior to a Dart. No doubt about it.


Why did I get rid of that car? BEcause it did not have AC. Dummy me.

I have a Weber 38DGES on my slant. I had to jet it down a couple of sizes. A while back, I used a Holley 2bbl carb from a 360 which was supposed to be 350 cfm. I used this carb for about a year, and I never got it to run great. It would start right up, but it took awhile to warm up, and it seemed to bog when I got on it.
It might have worked fine if I knew more about tuning carbs, but I found another carb to use.

As Wesola78 said the Holley 2210 and 2245 just won't run right on slants. Terrible for internal vacuum leaks too, but personally I would avoid them; been there, tried that.

The motorcraft/autolite 2100 with 1.21 venturi off of a 351 to 390 Ford is a great cheap carb to use for above average fuel needs. Running this on my slant and averaging 17 mpg during in town driving with an automatic tranny.
