These Carbs any good for 235?

Are these Carbs a good choice for a dual or triple carb setup for my 235? I'm kind of new to the inline six world so I'm not too familiar with this stuff yet. They are Rochesters but look like they are for the later 235's ? Not too sure so i figured I'd ask the experts!

In my opinion these B's are the most practical for your application. They just look, perform, and tune better than Carter's.

 

I'd recommend going with Carter W-1's. The 574s is a great carb for your application. Lots of info on this site, do a search.

Thanks for the input fellaz. Yeah I tried to do a search but I just didn't know the name of these carbs. Anymore input would be great

 

Dick is one of the undisputed intake experts on this board, in fact I just had him set-up 4 deuces for me. The reason I like the W-1's is that they use a mechanical power system which for me, is much easier to tune on multiple carb set-ups than those carburetors with a vacuum power system.

When selecting carburetors for a multi-carb system, the SIZE of the carburetors is the first criteria.

As to brand, pick a brand with which you are COMFORTABLE, because you are going to have to modify virtually any of them for peak initial performance.

Brand does matter when you consider reliability. And (my opinion, others may differ) while Rochester made "bullet-proof" two barrel and four barrel carbs, I cannot recommend the Rochester single barrel units. This statement following almost 50 years of working on carbs.

Carb king has the experiance and good advice. And a good link.

However, two years ago I put a pair of B's exactly like them on my 235 with an Offy manifold.

I replaced a 2GC that I had on a modified stock manifold. I really liked the 2GC, but the stock manifold was hurting me when I startred drag racing the car. Street driving was great, and 21 MPG hyway, too.

Anyway, had some trouble with the B's. The biggest item was leaking from the accel pump slots. fixed this by lowering the fuel level. I think 1/8 in from the spwc is where it's at now and no leaking.
Drivability is OK, but not as nice as the 2GC was. Did the modifications that the Rochester book recomended, drilling out some of the internal passages. And finally needed to rejet to get them rich enough to have a tan plug reading.

Gas mileage is now in the 16 to 18 range. Idles nice at 800. pulls good off idle. Drives well.

Now the 1/4 mile times with the 2GC were 20 seconds. With the B's it's been to a 17.36 @ 80mph.

MY opinion surely doesn't differ!!

THIS book?

YES. good info, in there, helped me with the 2GC's over the years and the B's.

 

Those are B's from the later chevy inlines. 230 or 250 maybe.
Bigger than those for the 235/261.
I had a pair of those on my 235, many years ago, which was way too much carburetion for a stock street motor with headers.
Even a pair of 235 carbs were too much for this engine.
I ended up with a pair of late 1940s 216 carbs on my 235 and 261.

 

I like the Carter W-1 ....

 

...

 

I run a pair of Stromberg BXOV2s on a McGurk intake on the 235 in my '53 BelAir, and couldn't be happier with both performance and fuel mileage.

 

One of my favorites, actually.

thats just because you are a rich parts guy and the rest of us can't afford parts like that. I hope you are happy.

 

You're such a hateful boy.
