Does anyone know if a Carter WA-1 will bolt onto a stock 235 intake? I'm trying to upgrade from my leaky Rochester. Thanks
nope - it has the narrow bolt mount pattern for a 216. Everyone hogs them out ruining the carb. Plug and redrill the manifold (or put dual carbs on it)
Thanks for the info 6inarow, I didnt realize there wa a difference. I guess I should look for a YF from a 235 or 250?
In my opinion the YFs are good carbs had one on my 56 for years and never gave a lick of trouble. the other one to look for is a Stromberg BXOV-2 - probably the best carb made for us inliners. Hopefully Jon will chime in soon......
Didn't know about the Stromberg, thanks! I'm having a hard time finding the right YF, I'll add the Stromberg to my search.
The Chevrolet 216 and pre-1950 235 engines used S.A.E. size 2 carburetors. The 1950 and newer 235's used size 3 carburetors: http://www.thecarburetorshop.com/Carbshop_carbsizesandCFM.htm On a Stromberg, the number following the letters is the S.A.E. size: http://www.thecarburetorshop.com/Strombergcodebreakdown.htm For some reason I have never understood, and the engineers at Carter that I asked didn't have the answer; The number following the model letter on a Carter is one less than the S.A.E. size. So, examples: Carter W-0 is a size 1, W-1 is a size 2, W-2 is a size 3. The WA-1 is a size 2. Carter discontinued the coded size about 1950. The only way to know the S.A.E. size for a Carter YF is to look up the carburetor identification number in the Carter Master manual. Examples of Stromberg: BXOV-2 is a size 2, BXUV-3 is a size 3. THE ABOVE ARE PHYSICAL SIZES! Once one determines the physical size to fit the manifold, one needs to determine the internal (venturi) size to properly run the engine. Stromberg and Zenith both published charts to help with this; but in the absence of a chart, one can GUESS that a carburetor from a similar engine of similar displacement may be used. Here is a list of the Carter YF's for Chevrolet that I compiled from the Carter records: Carter YF carburetors produced for use on Chevrolet 756s – 216 engine aftermarket 1937~1952 787s – 216 engine aftermarket 1937~1952 788s – 235 engine aftermarket 1950~1952 789s – 235 engine aftermarket 1950~1952 890s – 235 engine aftermarket manual choke (number assigned, no production) 891s – 235 engine aftermarket auto choke (number assigned, no production) 964s – 216 engine aftermarket manual choke 1937~1952 965s – 216 engine aftermarket auto choke 1937~1952 966s – 235 engine aftermarket auto choke 1950~1952 967s – 235 engine aftermarket manual choke 1950~1952 2008s – 216 engine aftermarket 1937~1952 2046s – 206 engine aftermarket 1932~1936 2100s – 235 engine aftermarket manual choke 1953~1956 2101s – 235 engine aftermarket auto choke 1953~1956 2104s – 261 engine aftermarket (number assigned, no production) 3055s – aftermarket (number assigned, no production) 3211s – 235 engine aftermarket 1957~1962 3379s – 153 engine original equipment manual trans 1962~1966 3402s – 153 engine original equipment auto trans 1962~1966 3711s – 194 engine aftermarket 1962 3760s – 230 engine (number assigned, no production) 3770s – 230 engine (taxi) original equipment auto transmission 1964~1965 3771s – 230 engine (taxi) original equipment manual trans 1964~1965 3772s – 194 engine auto transmission (number assigned, no production) 1964 3773s – 194 engine manual trans (number assigned, no production) 1964 3821s – 194 engine (van) original equipment 1964 3946s – 194 engine aftermarket 1964~1965 3946s – 230 engine aftermarket 1964~1965 3975s – 230 engine (van) original equipment manual trans 1965 3976s – 230 engine (van) original equipment auto trans 1965 4043s – 194 engine (van) original equipment manual trans 1966 4043s – 230 engine (van) original equipment manual trans 1966 4044s – 194 engine (van) original equipment auto trans 1966 4044s – 230 engine (van) original equipment auto trans 1966 4048s – 230 engine (van) aftermarket experimental 1963~1966 4072s – 194 engine original equipment auto trans CALIF smog 1966 4072s – 230 engine original equipment auto trans CALIF smog 1966 4073s – 194 engine original equipment manual trans CALIF smog 1966 4073s – 230 engine original equipment manual trans CALIF smog 1966 4080s – 194 engine original equipment (pass) auto trans CALIF smog 1966 4080s – 230 engine original equipment (pass) auto trans CALIF smog 1966 4080s – 250 engine original equipment (pass) auto trans CALIF smog 1966 4085s – 230 engine original equipment (truck) manual trans CALIF smog 1966 4085s – 250 engine original equipment (truck) manual trans CALIF smog 1966 4086s – 230 engine original equipment (truck) auto trans CALIF smog 1966 4086s – 250 engine original equipment (truck) auto trans CALIF smog 1966 4145s – 194 engine original equipment (truck) manual trans 1965~1966 4145s – 230 engine original equipment (truck) manual trans 1965~1966 4202s – 250 engine (taxi) original equipment auto trans 1966 4203s – 250 engine (taxi) original equipment manual trans 1966 4278s – (export to India) 4339s – 194 engine aftermarket 1963~1967 4339s – 230 engine aftermarket 1963~1967 4339s – 250 engine aftermarket 1963~1967 4367s – 230 engine original equipment manual trans CALIF smog 1967 4367s – 250 engine original equipment manual trans CALIF smog 1967 4368s – 194 engine original equipment auto trans CALIF smog 1967 4368s – 230 engine original equipment auto trans CALIF smog 1967 4368s – 250 engine original equipment auto trans CALIF smog 1967 4369s – 230 engine original equipment (truck) manual trans CALIF smog 1967 4369s – 250 engine original equipment (truck) manual trans CALIF smog 1967 4370s – 230 engine original equipment (truck) auto trans CALIF smog 1967 4370s – 250 engine original equipment (truck) auto trans CALIF smog 1967 4371s – 230 engine original equipment (truck) manual trans CALIF smog 1967 4371s – 250 engine original equipment (truck) manual trans CALIF smog 1967 4371s – 292 engine original equipment (truck) manual trans CALIF smog 1967 4372s – 250 engine original equipment (truck) auto trans CALIF smog 1967 4373s – 153 engine aftermarket manual trans 1963~1967 4374s – 153 engine aftermarket auto trans 1963~1967 4375s – 230 engine original equipment (truck) manual trans 1967 4375s – 250 engine original equipment (truck) manual trans 1967 4376s – 230 engine original equipment (truck) auto trans 1967 4376s – 250 engine original equipment (truck) auto trans 1967 4377s – 250 engine original equipment (taxi) manual trans CALIF smog 1967 4378s – 250 engine original equipment (taxi) auto trans CALIF smog 1967 4387s – 194 engine original equipment (truck) manual trans CALIF smog 1967 4480s – 230 engine aftermarket (all Federal) 1963~1967 4480s – 250 engine aftermarket (all Federal) 1963~1967 4492s – 194 engine aftermarket 1962 6213s – number assigned no production Jon.
