new manifold set not quite the same as the old but perhaps this is what I really need

My 36 Plymouth has a T310 230 CI Dodge engine (from 52 dodge truck).

The manifolds and carb that my engine had when I got the car appeared to be the original manifolds from the 1936 Plymouth 201 CI engine. The original carburetor is a 1bbl Carter B+B. My machine shop told me that there was too much corrosion between the intake and heat riser box and that it would be more cost effective to get a reconditioned one. I got a set from vintagepowerwagon.com that was supposedly compatible with my engine.

It does appear that it will bolt on to my engine and mate with my exhaust flange (correct manifold that will fix stock exhaust flange position).

In the pictures below, the one with the new carb studs is the newer one that I just bought.

However, ther eare some things that are different about this manifold that appear to dictate that if I keep it I will have to change my carburetor. I have pics below. The two studs for the carb were closer together on my old intake (appears to be 2 11/16 inch spacing on the old one and 2 15/16 on the newer one). Also the diameter of the intake is a little wider on the newer one (old one looks like about 2 1/2 inch and the new one looks like 2 5/8 inch). Also, on the old one there is a flange that sticks up on the intake manifold that the newer intake does not have. The mount points that were provided are similar but they are at a different height (but it seems to be same after you account for the lack of hte extra flange height on the old intake. The heat riser box flapper design is different on the newer one.

The newer intake appears to have a lot of extra vacuum ports.

new intake date stamp appears to say 6/5/62 - casting num: 1066051.

I don't know what it was from but it is clearly newer.

old intake has this number on it: 651259-16

Does anyone knmow what carburtetor is recommended for this other intake manifold?

Here are some various angle pics:

I had an idea, was this intake from a propane carb fork lift?

Is there any dissadvantage to this? I was thinking that I would mount a vacuum gauge on one of the extra ports.

Rebecca , I came accross one of those carburators that had the smaller spacing on the mounting bolts and ended up switching the top portion of the carb to an older base that was wider . VPW sells a lot of dodge truck military stuff from the 1940 's . NOS , used , and reproduction .

the new manifold has wider spacing not narrower spacing. What I mean is my old manifold which is a much older one, has narrower spacing so my old carb won't bolt on. however, since my engine is a newer engine, perhaps it is just as well that I use the newer manifold and get a bigger carb but I don't know which one. also, I am curious to know more about this new manifold. was it from a natural gas driven fork lift? How does that hook up?

Pre 40 (201) had a smaller carb with a different base. Later models these were used on taxis andother comercial vehicles as an economy measure. They also had a smaller throttle bore. Perhaps you machine shop can make a spacer block that will adapt the olde carb to the new manifold. The extra height won't be an issue with your tall hood and If they make it out of aluminum the insulation factor will be a bonus.

the new intake is shorter (missing the taller flange), has a larger bore, and larger spacing. What carb should I look for?

There are a lot of ports on this new intake. What were they for? Was this from a natural gas fork lift or something else?

Would you agree that this manifold is better than what I had before because I should have a larger carb with my non stock larger engine?

A standard ball and ball Carter 1 barrel from 1946 and up should work. As for the propane question, not too many of us here have discussed that topic, asking 3 times in such a short amount of time isn't likely to bring a quicker answer.

I think you're right Rebecca. If your motor is a newer one, like a 218 or 230, It might benefit from the larger carb. The Ball & Ball carbs show up pretty frequently on ebay. I'll pm you.

just last month i had a ply friend come up to get a pre 40's carb....and he had the manifold with the slightly closer carb studs.....

rebeca...SCRAP THE WHOLE SET-UP......sell it off.! get the right one that works with the carb you ahve . saw one on ebay last month for 50 bucks, the set. i think there is one now... search..."plymouth flathead manifold"

lots of us have extra manifolds......especially intakes.

It would seem more likely that the extra ports are for vacuum pwered accessories and or a gauge. If you contact George Asche ( he is in the vendors list on the main page of this forums host site. He will sell you a remanufactured carb or perhaps the number of the later style carb.

I've not heard this before. Dads 39 had the "normal" sized carb like the 40s and up cars. His car still had the factory 201 in it. I do know they had an accessory economy package which interestingly enough usually got you a 3.73 rear end. I've got an intake in my truck that I took out of a 35 and I have the "normal" sized carb also. Granted that was a junkyard car and I didn't check to see if that one still had the original intake or whatever. It did have those 2 ears in the correct spot for my throttle linkage.

My 35 Dodge with it's original 218 engine came to me with the smaller bore carb.

I replaced the carb with a larger bore Stromberg and had to have the mounting holes elongated inward to fit the smaller bore intake studs.

You can see the outside of the original hole in this photo. Working fine.

It may be an illusion but your new manifold looks longer than your old manifold. It may be for a long block (Crashler, Desoto) engine. Do the ports line up on both manifolds?

As far as a natural gas fork truck I would think such an animal would not have been driven past the end of a driveway (Norms Coupe should pay attention here as he may want to convert his car to natural gas) as the fuel line length would be the limitation. :D

Now if it were a propane fork truck the manifold should be the same as a gasolene powered vehicle as the only difference was the carburetor.

Claybill, why do you say that?

Rebecca, I have a 230 in my '35. When I replaced the older manifold with the smaller carburetor with a newer manifold with a larger carburetor, the engine ran better.

The larger engine definitely benefits from having a larger carb, just as it benefits from the larger exhaust just as it would benefit even more from dual carbs and exhaust.

ha ha. yes, propane. I almost fell off my chair laughing.

The ports seem to line up exactly. It is definately not fr a long block.

Yes, my ultimate plan is to do get it to breath better but for now I just want to get it running. I must need to find a carb.

Jim, what carburetor do you have on your 230?

I did some checking around today. I thought it would be easy to find a cheap carb. I did bid on a couple things on ebay but there was not a lot of info so I am not sure what I bid on.

My carb is a B&B D6G1 ('42-'48).

If I remember correctly, the carb has the same bolt spacing for the base of both carbs. It is the throttle body that mounts to the manifold that has the different spacing. If you can't find a new carb, you may be able to find a throttle body that would let you use your old carb on the new manifold.

Hi Rebecca, I've got several carbs you can choose from, and have your pick. I'm in Maynard, on Nason Street. Stop by some time. Send me a PM.

Don, our local natural gas company which supplies residential and industrial natural gas runs most of it's large fleet of service trucks on Natural Gas :eek:

They compress it and store it in a tank similar to an automotive propane tank.

A few people have private CNG vehicles with refueling ports at home as well.

So, not as far fetched as it seems :D

Our local power utility also runs many trucks on CNG. Most of the ram tractors, fork lifts, sheet carriers, and shop mules at US Steel ran on CNG too. I remember a few years ago there were a lot of CNG powered taxis in Las Vegas.

The oil stays clean forever and they have a sweet smelling exhaust.

Pat S. back when Ann Richards was Governor of Texas we Converted most of the motor pool fleet to Natural Gas and gasoline. The Natural gas gave lousy mileage. After she left office they swiched all of the cars to Propane which gives much better mileage. One problem with compressed natural gas is that it is only available in limited places dues to the specialized equipment required to compress it while propane is available everywhere in Texas already compressed.
