VCCA Home Forums TECHNICAL - 1945 AND NEWER 1949-1954 Intake manifold #

I was unable to find my intake manifold casting number in the parts book the number is 3836922 OR 3838922 I'm not sure if the 4th digit is an 6 or an 8. I was able to locate the exhaust number without any problem. I was also trying to find witch carburetor I need but the book has a note "except COE" Do you know what this means?

"COE" means "Cab Over Engine".

Ok,I don't have a cab over but what about the casting numbers and carb ID Thanks

It all depends on what year car you have as to which carburetor would be correct. You never listed the year of your car in your posting. :( :( :(

I have a 1952 235 with a 3 speed trans in a 1951 sedan delivery.

You should have a Rochester single-barrel carburetor. The number on the ID tag is 7004476. The number cast on the throttle body is 7002128 and the number cast on the float bowl is 7004497.

I D tag???, after 52 years most of the ID tags on any Rochester carbs I have seen have vaporized!...Well anyway they are gone......fortunately there often are numbers cast into or stamped into the cast throttle base. I just try to get the correct size throttle base bolt hole spacing for the engine a 216 is different than a 235 and the 51 3 speed 216 used a manual choke carb, at least the two 51 three speed cars I have are manual choke. If your 235 was a powerglide engine it probably had the larger bolt pattern Rochester with an auto Choke originally. Your engine may be a Utility engine (truck) which uses the carb JYD listed and it should have either a #56 (one step lean) #57 (standard) or #58 (one step rich) metering rod jet.

we conclued that my nos 235 engine is a truck engine
per topic CASTING NUMBERS dated Sept 21 04 so it looks like I need the Rodchester. This is turning into a nightmare now Buster Brown (UPS) has lost the tool I sent for to align the oil dipper troughs in the pan.Whats next? the wife finds out and kills me and sells my SDL?

Lets start from square one.

Intake manifold
There is only one intake manifold made for 1950-58 235 engines-car or truck.Its casting number 3835590.............The1959-62 manifold will also fit and work OK-there is not a casting number listed for it but the part number is 3754644,The only difference is that the manifold is contoured lower to lower the carb. due to the lower hood line on the newer cars.Exhaust Man. fits all 235s from 1950-62.I find no reference to the casting number you listed???

Carburetor

Any 1950-56 passenger car (with 235 engine) or 1950-62 truck (with 235 engine) will fit and work perfectly well...1952 Power Glide and all 1953 and up cars had an automatic choke so an intake manifold heat stove would be required..
.If you purcahsed a new carb. for a 1952 PG in 1961 it would have been a 1956 (improved) carb....same for the hand choke jobs.All original carbs were Rochester.A Carter YF was sold by Carter for replacement but never installed from factory.

Good luck with lost shipment-at least UPS shipments are insured

Insulator block
Very important to have the bakelite insulator block under carb-available from Chevs of the 40's.

Identify carb.

235 carb (and intake manifold) has the wider stud spacing (wider than 216)...2 15/16" center to center on studs (or holes)...Also the throttle bore (and plate) are 1/16" larger-1 7/16" on 235.

As a note-yes a COE truck (and DD=duble duty+=stand up and drive)has a different intake and exhaust manifold due to the up-draft carb. used.....but these are seldom seen and look like something from 1929

On the lost tool from UPS, did you ever run the tracking number on your computer to find out where the package was last seen? UPS has an excellent tracking system and when a package is shipped you can track it on your computer daily. :cool2:

Yes, The package found a new home near Chicago last Friday.

Thanks Chevgene;I'm glad you were unable to fine the number either, I though I was looking it up wrong or something. I'm not sure what I have now. The exhaust manifold has the right casting number for a 235 and they seem to bolt up to the head OK together.

Like Gene said a 235 intake is a 235 intake unless it is an updraft, or an after market for multi carbs, which are very easy to detect. I have a couple of 235s and even a 216. My problems with manifolds are broken or cracked exhaust manifolds, with the heatrizer frozen ot missing.When I try to seperate the intake from the exhaust after they have set outside or been on the engine for 50 years and the connecting bolts and capscrews are rusted in and twist off. When that happens sometimes it is better to take them to a machine shop to drill out the dutchmen.
