5 Best Carburetors for Chevy 350

The role of a carburetor in an engine is to provide the engine with the correct mixture of fuel and air. This is important for ensuring that the engine can run properly and generate power. Without a carburetor, the engine would not be able to function properly.

Though the engine comes with a pre-installed stock carburetor, some car owners are always looking for ways to boost their engine performance. One such way is adding an aftermarket carburetor to the engine.

If you are in search of an aftermarket carburetor for your Chevy 350, look no further. I have gathered some of the best options you will find in the market.

Things to Consider When Buying a Carburetor

Lastly, I would like to mention a few important things you surely have to consider when looking for a carburetor.

Carburetor Size

You need to pick up the right size for the carburetor. This size is measured in terms of airflow through the carburetor, CFM (cubic feet per minute). To determine the right size for your car you can use the following formula,

CFM = (Engine Volume (cc) x  Engine Max RPM) / 3456 CFM.

For instance, if we consider the case of the Chevy 350, the engine volume is 350 cc, and the rpm is about 5500 rpm. On substituting the values, you get the estimated carburetor CFM you need for your engine is 557 CFM. So, any carburetor offering more than 550 CFM will work fine in this case.

CFM = 350 x 5500 / 3456 = 557 CFM

Choke Type

You also get to see a choice in some carburetors where you can either go with an electric choke or a manual choke, as seen in motorbikes. The electric choke is much easier to control in my opinion. However, you can go for the one which you are comfortable with.

2-Barrel or 4 Barrel

You may have seen 2 -barrel or 4 -barrel on the carburetor specification. The 2-barrel is smaller in size and defaults on most vehicles. Whereas, 4 -the barrel is bigger, offers more air volume, and significantly raises the engine power.

Final Words

Finding the right carburetor for an engine like Chevy 350 is hard. You need to have sound technical knowledge of carburetor sizing and other factors that come into play. In this article, I tried to make things simpler by listing down a few best carburetors and sharing how you can find the right carburetor for your engine.
