225 v6 2bbl Intake?

Hi!
I have a 1965 225 V6 with the 1BC single barrel on it. It hesitates bad when your in the throttle and I've been through 2 rebuild units now trying to fix it. Something to do with the neoprene or plastic valve piece in the accelerator side of the carb. it keeps getting stuck. when unstuck, car runs fine. Read about the leather piece idea, but changing it every 1-2 years sounds like a pita.

So - I am trying to source a 2bbl intake and carb (probably will need an air cleaner duct as well? don't know if the single will fit on a double)
I found that the casting number (or at least one of the casting numbers) I can use is 1378704

I did find 4bbl intakes for my 225, but some people say they work with a 4bbl, some say they don't. I'd be fine with a 2bbl setup IF I could find an intake. I think the 225 went to a 2bbl setup in 1966-71 If I'm reading correct, so any buick/olds/jeep from 66-71 will have a 2bbl intake that can be used? I also read that perhaps a 231 2bbl intake can be used as well? (not sure)

I've already changed the coil out and went with a HEI setup, but could really use some help with what to do with the intake.
thanks!

Pretty sure all the Buick cars pre-66 were 1V, and all Jeeps got the 2V.

You should be able to find a 2V manifold.

 

What exactly are you trying to accomplish here? I'm not really following.

Sounds like you're trying to fix your stumble by getting a 2B carb instead of a 1B?

 

The car has a 1 barrel intake and a 1bc carb stock that doesn't run right

I'm looking for a 2 barrel intake and carb to make the 225 run better

Yes- after 65 Buick and jeep went with a 2 barrel intake and carb for the 225 v6 that will fit my 65, so that's what I'm looking for

 

You would think so yes
But so far I can't find a 2bbl intake for the 225

Aftermarket 4bbl intakes - yes, but nobody is reproducing the 2bbl, have to find a used one somewhere

 

I guess I'm not engine savvy enough. I was under the impression that the first 225s were 1B.

 

1965 Dauntless used Rochester BC .
In my estimation it's one of the worst carburetors ever built.

1966 Dauntless used Rocchester 2G or 2GC.
In my estimation it's one of the best carburetors ever built.

Apparently the single barrel manifold tends to limit the volumetric flow on this particular engine.

 

I have a 2bbl newly rebuilt Rochester carb and a 2bbl intake sitting on an engine stand. I have not checked the model number yet. I just sild the stock intake manifold so I cannot help you there.

Sorry about that, I should have said, just sold the stock air filter.

I sent you a PM

 

awesome! I'd be interested in buying the intake manifold and carb. please let me know, thanks!

 

yes, you are correct. my 65 HAS a Rochester 1 barrel 1BC carb on it, and it doesn't run right. I tried to replace the 1BC carb with 2 rebuilt units, but bothe the rebuilt units had the same issue. The accelerator side of the carb hesitates due to a sticking piece.

this is why I'm looking to replace the stock single barrel intake and stock single barrel carb with a 2 barrel intake and carb from a later model (66-up)

 

I thought the first year for V6s in CJ-5s was 1966? :? Any V6s in earlier Jeeps would be swaps, and should have the T-90, not the T-86.

If so, the OP's Jeep is a swap, and has a passenger car engine. What's the VIN?

 

V6s for Jeeps was 1966, correct, which is why I came here looking for the intake and carb

the V6 I have is in my 1965 Buick Special, which is a one barrel intake, 1BC carb setup. I guess this is where the confusion is. My apologies. I should've stated that this request is for my CAR, not my Jeep. My bad, sorry guys!

 

CJ-3B ended (domestic) mid 1965 model year.
Jeep Dauntless began production late in the 1965 model year.
All Buick 225 and 1965 Dauntless 225 had the Rochester BC.

 

Ok, I hope you have some idea of what they re worth. I was in error on the 2bbl carb, it has not been recently rebuilt, I confused the invoice i had for a starter rebuild. So if you have an idea of what they are worth to you , make me an offer.

If you are not going for a stock restoration and find a good deal on one of the aluminum 4bbl set ups, go for it. IMO, they work very well, even without a cam change and if you can keep your foot out of the secondaries, they will actually get better mileage than the 2 bbl.

 

I would think the 390 CFM Holley 4V would be fine for a 225 cid Special. And it would drop on to an aftermarket aluminum manifold. Easy to tune, lots of aftermarket support, cheap parts ... http://www.holley.com/0-8007.asp

 

I've heard the 4bbl is too much air for the 225 (some people say this, not all)
not to mention - 4bbl aluminum intake $250+ and a new 4bbl carb $400+
I think I could put a 2bbl intake and get a 2GC carb for less than that. Just want it to run well, not concerned with HP at the moment.

Someday I'll probably put in a 350..or even a big block

 

I guess its been a long week. Whenever I read a description of the issues you're having, I someone interpreted it as an issue of a undersized carb being swapped on. Definitely go for the 2G 2bbl as others have said. Excellent carb.
