I have a 235 in my 53 chev 1/2 and I want to put a fenton intake with two carb set-up on it. My question is this whats the better carb to put on this set up? 1. Carter W-1, Carter Y-F or a Rochester? 2.Is there a other carb I should be looking at? 3.Should it be the carbs for a 216 or the 235 because I'm now going to be using 2 of them? Anyone with an opionion!!!!!!

Any suggestions would be Appreciated!

Whether you use 216 carbs or 235 carbs will depend on the manifold you are using. The bolt hole spacing is different.

As another option for the 235 I would suggest you consider a pair of Carter/Webers. I found that the supply of decent Rochester and Carter cores was fairly limited so I made the transition to a single Holley/Weber on my stock 57 235 in my 54 truck. It performed flawlessly out of the box. Totally eliminated the rich condition and leaking problems of the 50 year old Rochesters.

On my replacement 1960 "built" engine, I went with the dual Carter/Webers as I was building for low-end torque. As with the single H/W, the dual C/W's performed flawlessly right out of the box. Set and forget. I've put over 4500 miles on my 60 engine and haven't had the first hiccup!!! My truck will cruise all day at 70 mph@2000 rpm's and my AVERAGE fuel consumption varies between 18-20 mpg. I know it could be better if I were a bit more attentive to my speed and driving style.

If you were camming for a higher torque/rpm, you might be wise to consider a pair of H/w's as they are rated at a bit higher CFM. I've documented my H/W and C/W installs in my Webshots...you might take a look at the process and see if this combination would be something you might want to consider. Granted the H/W and C/W's are visually "different" from the stock style carbs but they certainly make up for it by being great performers, a reasonable initial cost, in the ease of installation and tuning and don't seem to be effected by the blended fuels we are faced with using.

Tom Langdon of Stovebolt Engineering Co. is a great source of information on this setup as well as other 235 related info. I wouldn't hesitate to use this C/W setup on any vehicle that I wanted to perform flawlessly.

I'll agree with Dave. I just swaped out a pair of Rochesters with a pair of Carter/Webers on my 235. What a difference, no more leaks, no more hesitation, just smooth running. Well worth the effort.

Are Carter Webers called Carter W-1 carbs? The reason I ask is thats what the listing is at "Jim Carters" Web site! And my Manifold is a Fenton Dual Intake Part # HP107 For a 235 and 261 High Pressure! Hope this helps with the advice!!!!

No...the Carter/Weber is a progressive 2 bbl carb that works well in pairs on a 235.

Forget the dual carbs and go with a single four barrel 375cfm Holley. Twins are just too hard to keep calibrated, don't add any real power, require adaptors from 2 to one barrel, unnecessarily ugly linkage and really only have the WOW factor in their favor IMO. I would not do it again but have a look see at my website if you insist.

Clear as mud eh Jason? Interesting to note two long time Dave’s running Langdon’s setup suggesting completely opposite directions. For sourcing a quality pair of rebuilt carbs in Canada I suggest Autoline. The pair of Rochester B’s I got thru a FLAPS ran great out of the box and were $90.00 each w/ $50.00 core. All the one barrel carburetors that directly bolt on are designed to be vertically actuated. Pressure should be from directly underneath where the rod attaches and at idle it should have a very small window where it will “float” or exert no pressure on the carb so that it is resting against the idle stop. This all becomes polluted with a floating linkage that firmly clamps the carbs together and exerts pressures against the throttle shafts that are not designed to be there not to mention flexing. Anyone who has an intake with a pivot rod does not have those issues and IMO most dual carb complaints are linkage related and not caused by the carbs themselves. If I ever wanted something other than Rochesters it sounds like Strombergs are the ultimate hot rod carb.

Wow! those Strombergs look nice and the "Price" seems to match(Expensive)!!! but Rochesters looks a little more reasonable in price for me!But are there any advantages or disadvantages for the carter carbs?

I think the intake I ordered takes a 235 carbs

Here's another option, the Holley 1904 single bbl. Uses the same jet at any later Holley 2 or 4 bbl, so they're easy and cheap to get, unlike the metering rods and whatnot for the Carter carbs. Also very easy to overhaul. Look for them on GMC and International trucks.
