Holley Weber 2 barrel on a 235?

Well Ive read good and bad reviews on this switch offered thru Langdon Stovebolt 6. Its a cheap way to add performance and mileage. It's about $125 thru Landdon's with their 2 barrel adapter and linkage kit. For a stock Rebuilt engine with Fenton headers and mallory electronic distributor, it seems like a good next step.Any opinions, reviews, alternative ideas? This is for a 53 3100. Has 12 bolt rear with saginaw 4 speed. Anythings better than the rochester B, but is this good bang for my buck or just something I'll want to replace later?

 

I have not used this carb on a 235 Chev, but I have many miles with one on my 200 ford six in my Falcon. I have always thought that this would be a pretty good swap on one of these. The only time I have ever seen one used on a Chevy was on Pat Ghannal's '52 years back when he ran two of them.

 

the only problem is that it is uglier than sin

 

It will work but they are pretty small cfm wise. Ford had them on Pintos.

 

They are supposed to be good for about 125 hp. Should offer good economy and snappy low end performance.

My son had one on a 200ci six and it was a little lean. I do not know if you could bump up the jetting a little.

 

I bought one and couldn't for the fucking life of me get it to work. I tried everything. The linkage they sell and all that was fine, bolted on with a little figuring out (they don't give you shit for directions) and she fired up great, idled very smooth, but I couldn't get ANY power out of it, I was lucky if I could take the car up to 30 mph.

 

Wow Kojak, that's a bitch. The Langdon"s are rebuilt, and that can be kind of a crap shoot. If I ever add a different cam and get some valve work done, I could add a 2x1 intake with another adapter and add a second holley weber or switch to better one barrels.

 

Guys I put one on my 235,its in a 51 3100 with a T5.I runs a little lean 17 mpg on the hiway.The linkage kit did not work for me,went with Lokar cable and pedal assembly.I went with this setup cause I was on a budget I know this motor would run better with a larger or multiple carbs since the cam is not stock.

 

Tuning the Weber is different than most other carbs. For example, your first step is to select the proper low speed jet and idle adjustment! Here is a good place to start, there are other sites on line that are helpful.

I do have to agree with butt ugly! And yes, you will have to jet one properly for your application, that kinda goes with out saying. AND, yes a Weber or Holley Weber is a bit more complicated to tune, But you do have a much larger range to be able to tune for. You do need a book to get the most out of these things. The one I have been using for the last twenty years is "WEBER carburetors" by Pat Braden. It was put out by HP books. Every VW shop out there has a copy for sale, and I'm sure Barnes and Nobal could order it for you as well. This book and a couple others have a kind of step by step approach to jetting these things, that starts with what displacement you are working with. It will make your life allot easier.

 

That's helpful information Thanks.

 

There is also another HP book, 5200 Holley handbook which is pretty helpful. I foud one on E-Bay.

 

The Weber 36/32 DVG is the carb the Holly was copied from. The Holly's have internal warping problems , were the Webers are trouble free. I ran a single 36?32DVG on a dynoed 2.0L Ford and put out 200HP in a road race car and the Weber is very tunable.

I had a pair of them on my 250. Three time winner at "Run what ya brung". They worked good enough for me.

 

And they were too small for the Pinto's, a 350 2bbl Holley could really wake up a Pinto.

 

I ran one on a 235 inch Mopar flathead and was very happy with it. It did require bigger jets to run right. With a manual choke it was very dependable, eliminated hot start problems and would get 20 mpg with overdrive. The smaller primary provides better low to mid-range torque.

 

Stopped in at my local parts house and asked for a holley weber from the pINTO sAID THEY COULDN'T GET ONE . Haven't tried NAPA or anyplace else. $75 from Langdon plus shipping. Anybody buy one somelpace else?

 

Butt ugly yes.Two of them work well on a 230-250 cube inline 6.One carb can reduce part throttle performance because it runs on the small primary bore.When both barrels open the power should be better than a stock single barrel carb.What you get from the Holley Weber depends on how good or bad your stock carb is and what your expectations are.For a Chevy,A Holley 1920 from a Slant Sled Mopar with minor modifications to the throttle lever or a Carter YF 2100 repalcement carb is a big improvement over a Rochester.

 

The 2000 CC cammer in the Pinto took a deeper breath than a stock 235. It will draw more than enough air when you need it. You'll need to rejet accordingly but that's normal with about any carb swap, I think.

As far as performance the only setups I'm familiar with were twin carb setups. They seem to work real well once properly tuned.

 

got mine off ebay 2 weeks ago, he has more. $75. Langdons has been out of them for a while. Got the adapter from summit.

 

they were the tuning carb to go for in England for 1600 and 2000 ford xflow if you were on a budget,if memory serves me the pre emmissions ones were the ones to get. once you get used to them you can tune the crap out of them.Look on uk site,s for older rally type cars, escorts, cortina and capri (all ford)

 

I also seem to remember you could change the venturi"s (spelling) on the older ones.

 

I'm not sure about the venturis, but I do know that you can jet many different functions of these carbs to make them suit your needs. I just walked out in the shop to check some thing, the difference in venturi size. Now I have the Weber, which is a 32/36. And, I did these in metric, so don't shoot me ( that's not normally how I roll). The Rochester that came off one of my 235 Chevys was 38 mm that's about a 1/4" bigger. The Autolite single that came off of my 200ci ford checked in at 35mm. I did that just for comparison. So yes, the Holley/Weber, and the Weber are a bit smaller than the carbs they replace, but the originals were also both single barrels too. That second 36mm opens up, and you can feel the difference big time. If your still concerned about the size issue, Weber also makes the 38/38 DGAS carb, which is a synchronous two barrel that fits the same adapter.

 

I just put one of these on my stock 230. Got it from Langdon's, made up a linkage for it and its works pretty good. Idles nice and has decent low end power, but like mentioned earlier, no mid range or higher speed power...tough to get it over 40mph. hell my old rochester ran like crap but had no problem goin 65.

figure its running lean. anybody know what primary/secondary jets size they're running? idle jets?

 

A bit to small cfm, it seems. A friend w/ Dodge 218cid is well...hesitates hard on hill starts...On a other friends 54 Chevy 235cid it didnt function well, NO power in the midrange, great idle, and full speed was,well functional... but a big hole in the powerrange midways. 2 carb setup is great, but one.....No as we found out. It was the same carb tryed on both, and the Chevy guy tested and tryed tuning it with all efforts on the dyno, at a workshop as a mechanic
on one of Norways biggest carrepair..

 

I have a 2X1 set up from Langton thats been running for two years now. I have 0 complaints. I can't speak as to the power, but it idles fine and runs clean.

 

okay thanks alot for the info fellas. Sounds like I need to either go back to the rochester or buck up for another one of these carbs and a 2x1 intake.
