Two & Four Barrel Carburetor Best Carb for Chevy 350

2 Barrel Carburetor for Best Carburetor for 350 Chevy

There are many 2-barrel carburetors with very similar designs to each other. Some of the real two-barrel carburetors are the Holley 7448 and the 4412. In this case, these are two options that are between 500 and 350 cfm.

These data are at 3 inches of vacuum. A common feature of the carburetor is that it can provide excellent performance at high rpm.

In fact, when a high level of efficiency is required along with high rpm, then through each orifice of the carburetor, the fuel can flow more adequately.

However, nowadays, there are very few 2-barrel carburetors left because it is a model that does not offer as much performance as other options.

Specifically, this is because a two-barrel carburetor is a much smaller option than a 4-barrel carburetor. In particular, the carburetor allows a certain amount of air to enter the engine to produce the mixture with the fuel.

Holley 2 Barrel Carburetor Identification

On a great number of occasions, it can be really necessary to replace some components of the carburetor. This happens especially when the life of a carburetor is well advanced.

So this allows us to acquire the necessary parts to be able to apply excellent repair and maintenance. However, the different 2-barrel carburetors have different designs.

So it is necessary to know the list number after correct identification of our carburetor. Here it is necessary to find the list number that must be printed in some of the parts of the carburetor.

On many occasions, this number is located in a very visible way. Some of the most commonly used standard 2-barrel carburetor models are the 4160 and 4150.

All people who have this carburetor will be able to check the air horn throttle lever. Of course, between all carburetor models, some differences can be found here.

The oldest models include an R and are the models before the 1960s. Models after the 1960s include the letter L after a set of numbers. All carburetors with a more modern adaptation include the 0. 

Beyond that, it is possible to find four numbers, followed by a dash and a fifth number. This code is important as other codes are often included in the various parts of a carburetor.

However, codes that include letters usually refer to a particular code used by the manufacturer during the assembly process.

Thus, knowing this code will allow us to acquire the most appropriate parts that can be installed on this carburetor. If this code is missing somewhere on the carburetor, it could be due to some type of repair over the life of this part.

When the list number has disappeared, then it is much more difficult to identify a particular carburetor. In these cases, it will be necessary to consult a professional to determine specifically which carburetor is on your vehicle.

4 Barrel Carburetor for Best Carburetor for 350 Chevy

Unlike a 4-barrel carburetor, 4-barrel carburetors have the same characteristics but are larger. The 4-barrel carburetors have been specially designed to be able to achieve a higher power output.

In particular, a 4-barrel carburetor has 2 primary barrels and 2 secondary barrels. In principle, only the primary barrels open when the vehicle is idle and at low revs.

So the secondary barrels start to open and operate as the revolutions per minute increase. This is particularly important as more air can be drawn in for a better mix with the fuel.

On many occasions, a 4-barrel carburetor can be incorporated when a 2-barrel carburetor was previously used. However, this requires the installation of some special adapters.

Beyond that, 4-barrel carburetors are usually much more modern than 2-barrel carburetors. In the meantime, it is useful to think about the best way to obtain the list number of a given carburetor.

Nowadays many people wish to modify some cars to offer them more power. 

Holley 4 Barrel Carburetor Identification

Beyond the fact that this type of carburetor can present greater functionality and efficiency in a vehicle, it is also necessary to know the list number.

In this case, a specific number is also incorporated in some parts of the carburetor. In this way, it is possible to identify the exact carburetor model so that the user can replace certain parts.

Unlike the 2-barrel carburetor, the 4-barrel carburetor is a much larger unit. So this may increase the difficulty of finding the list number on some of the carburetor parts.

However, laser printing of the carburetor numbers is always included. Depending on each carburetor model, we will find the list number in different places.

However, it is most likely that the list number has been printed in a place with easy access or with a good level of visibility. When purchasing different parts for the carburetor, it will be necessary to have the list number.

On most Holley carburetor models, one of the front parts is usually considered. In particular, it is considered the choke tower. Generally, it is often a very popular place to stamp the number of the list.

Besides, a suffix can be incorporated on the back, although this is not always included in all cases. As with the 2-barrel carburetor, this carburetor can have a four to six-digit list number.

Beyond that, the date code is always included just below the list number. The date is not always as useful as the list number for purchasing a spare part.

In case you are not sure what the list number is, it is preferable to write down all the codes included in the carburetor. When purchasing the various parts that need to be replaced, all of these codes will be useful.

People who work selling carburetor spare parts can identify which is the correct code.

Buying Considerations About Best Carburetor for 350 Chevy

To complete our decision, we must mention the fundamental aspects of a carburetor. This is a set of aspects that will allow us to obtain a carburetor much more conveniently according to our needs.

Otherwise, you could easily make the wrong decision. 

Carburetor Materials

Of course, the materials from which the carburetor is made are very important to take into consideration. Especially a carburetor should be highly resistant and durable.

All those options that fail to deliver a good result deteriorate too quickly. In most cases, aluminum alloy is used with the addition of other metals to improve durability.

Here, it should be noted that high endurance to prolonged operation as well as high temperatures are required. With proper durability, the carburetor will have a long service life.

Fuel Consumption

In many cases, carburetors can increase engine power. However, in many cases, this also means higher fuel consumption. The carburetor is specifically responsible for incorporating a greater amount of air into the engine.

So the wrong carburetor could increase fuel consumption too much. So it is necessary to have a carburetor that is compatible and does not require a large amount of fuel to operate.


Beyond the materials used to manufacture a carburetor, the structure is another fundamental aspect. In this regard, the right structure can resist corrosion and various damaging factors.

Otherwise, the wrong structure offers not only poor durability but also a complex installation.

Manual or Electric Choke

As you may notice, there are two types of chokes that you may notice on the same carburetor. In principle, the electric version can offer a simple adjustment. Therefore, it is not required to regulate the airflow at any time.

On the other hand, the manual choke requires the labor of the vehicle user. So for some people, this may be somewhat complicated. Also, electric chokes can provide the ability to start a vehicle cold or hot.

Final Design

Of course, the final design of a carburetor is another of the most important aspects of getting a nice shiny finish. However, it should also be noted that this glossy finish is obtained with a bichromate finish.

Here it is not only a matter of enjoying a nicely designed carburetor. The dichromate finish avoids the problem of rust and corrosion. Even this feature also allows for longer durability. However, few options include this type of finish. 

Number of Barrels

As we have mentioned, there are two types of carburetors that you can choose from. When it comes to incorporating a low amount of air and power, then a 2-barrel carburetor will be more than enough.

However, this carburetor will not be enough when you need to reach high revolutions per minute. Therefore, this type of 4-barrel carburetor enables you to obtain outstanding efficiency.

Even this option also allows you to add some extra horsepower to the vehicle’s engine. Thus, it is a great alternative for anyone.

Throttle Response

One of the main tasks of a carburetor is to optimize the throttle response to complete the functionality and air intake. So the throttle response should be more adequate when you install the precise carburetor.

In other words, the response should be quick and without any delay. So the best carburetor will allow you to increase engine performance as well as potential and durability.

Even the right carburetor gets the engine running in a much better way to get a rich mixture of air and fuel.

Tuning Level

Any carburetor should be tuned to get the exact performance you need from your vehicle. Most of the time, we have considered carburetors that provide easy and quick tuning for most users.

So this means that any user will be able to have easy access to certain components such as fuel and airflow adjustment, filters, screws, and other parts.

Even in this way, the user will be able to adapt and get to know the carburetor better.

Possibility to Avoid Leaks

Finally, leaks can be very problematic when the user does not know how to deal with them. In this sense, leaks can sometimes occur from some faults inside the carburetor.

This is also related to the durability and the quality of the structure of this component. Therefore, the most appropriate carburetor can avoid the problem of corrosion and therefore decrease the probability of leaks.

So for this, it is necessary to have the most suitable budget.  Here it is not necessary to buy the most expensive carburetor on the market. However, the cheapest carburetor you can find will not deliver the performance anyone can hope for. 

Common FAQ’s of the Best Carb for Chevy 350

Q: What type of carburetor do you require for Chevy – 350?

Ans: When it comes to a stock Chevy 350, it can be very helpful to incorporate 600 cfm. In most cases, this amount can be more than adequate to be able to get a great amount of power and performance.

However, this carburetor can only be useful when a vehicle is kept with the stock parts. Conversely, the user will need a more powerful carburetor if he or she decides to increase power from other engine components.

Specifically, this could happen if aluminum headers, a dual-plane performance intake manifold, or a hotter cam are incorporated. All of these components optimize engine power on their side.

When this happens then, people will need to have a 700 cfm carburetor or even a carburetor up to 750 cfm. 

Q: How much performance does a carburetor of 650 cfm offer?

Ans: As we have considered, the right carburetor allows you to match each of your engine’s needs. When a 650 cfm carburetor is chosen, then this component can support the functionality of a factory Chevy 350.

So the amount of horsepower built into this factory vehicle will be supported by the carburetor. However, when a factory, Chevy 350, has other parts that increase horsepower, this carburetor may not be enough.

Many users can improve horsepower with a wide variety of additional components on the engine. When this happens then, a 750 cfm carburetor is probably needed to obtain the most suitable fuel/air mixture.

Q: Which option is more efficient, Edelbrock or Holley?

Ans: Either of these two options can offer convenient and affordable results to users. At first, it is necessary to consider that Holley carburetors can generate more power out of the box.

It is also one of the most reliable manufacturers in the market that many users choose to have a convenient carburetor. For its part, Edelbrock can provide adequate performance when a good performance at high rpm is needed.

In this regard, the latter option can offer a carburetor that is much more compatible with most Chevy engines. At the same time, the structure of each carburetor has excellent characteristics for formidable service life.

Q: What aspects are important to obtain the best carburetor for 350 Chevy?

Ans: To choose the right carburetor for a given vehicle, it is possible to take into consideration some basic aspects. Before anything else, it is worth taking into account the type of carburetor that is needed for a given vehicle.

So when only a carburetor replacement and an average performance is needed, a 2-barrel carburetor is more than enough.

On the other hand, a 4-barrel carburetor can be better adapted to users who want more power for their vehicles. In this regard, the latter option allows a large amount of cfm to be obtained.

Other important considerations in a carburetor are the structure’s durability and the grade of materials. This is fundamental to avoid the problem of corrosion or oxidation of the carburetor.

Finally, the installation procedure can be easy or complicated. When the installation procedure is easy, then it can be done by an amateur mechanic with the right tools.

When this procedure is not easy, then it requires the labor of an expert.

Q: How much power does a carburetor provide?

Ans: As we have mentioned, a high-quality carburetor has the potential to increase some horsepower to the engine. Here the experts assure that between 5% and 10% of additional horsepower can be obtained for adequate power.

Therefore, it is useful to analyze the amount of horsepower each vehicle has. Knowing the amount of horsepower of each vehicle is that it is possible to make the necessary calculations.

In any case, not all carburetors can provide between 5% and 10% more horsepower. However, when a carburetor increases horsepower, it means that it is a 4-barrel carburetor.

Usually, 2-barrel carburetors cannot increase horsepower.

Q: Is a 750 CFM too much for a 350?

Ans: When it comes to a stock Chevy 350, a 750 cfm carburetor may be too much. The wrong carburetor can draw too much air and end up choking the engine.

Instead, it is preferable to have a carburetor that delivers 600 cfm maximum. In this case, the engine will have an excellent amount of air but not an exaggerated amount.

However, engines with some modifications could have a 750 cfm carburetor. In these cases, it is a carburetor that manages to adapt to the higher power levels that the modified engine handles.

So this allows obtaining the most suitable mixture so that the carburetor can adapt specifically to the new engine parameters. 

Final Words

To have a vehicle that is much better suited to different light or heavy-duty tasks, it is necessary to have the best carburetor for 350 Chevy.

It is one of the fundamental components for the engine to have the right balance of fuel and air. In this sense, the right balance of these two components allows an engine with great performance and power.

Also, on many occasions, it is really necessary to replace the carburetor with a new and efficient one. So, this can be an excellent opportunity to opt for the 4-barrel carburetor that offers a higher level of power.
