Buyer’s Guide
In order to choose the perfect carburetor for your Chevy 350, look into the following factors.
CFM
The CFM needs to be balanced. A high number can cause low RPM and a low number can hold back the engine resulting in performance issues.
There’s a formula used to choose an ideal CFM carburetor for your car. It is:
For instance, 350ci X 6500 RPM)/3456=658.28 CFM
Intake Manifolds
Carbs can have various intake manifolds such as a dual plane, single plane, etc.
If you want low-mid range power then dual plane intake manifolds are perfect. These units produce less overlapping between the induction pulses, feed 4 cylinders in a v8 engine from two separate plenums, and have longer intake runs as well.
As for single plane intake manifolds, they serve all the cylinders via a single plenum which can cause overlapping between induction pulses. So, dual plane intake manifolds are a better fit.
Chokes
They help warm up an engine when it turns cold. There are two kinds of chokes: manual and electric chokes.
An electric choke is connected to a circuit and operates automatically. There’s no effort required in decreasing the air flow. On the other hand, manual chokes require manual control, which can be a bit tricky for some users.
Body
A carburetor with a corrosion-resistant, metal body is ideal as it prevents leak and remains durable due to no risk of corrosion.
Barrels
For extra acceleration, a higher RPM is required. However, a two-barrel carburetor won’t be able to handle higher RPM and might stall. If you wish to have better acceleration then you need to buy a carb that has 4 barrels.
They work in this way: When low-RPM driving and idling, only two primary barrels open up, while the throttle blades on the secondary barrels remain closed.
This is because two barrels are enough to handle the power and control air when the RPM is low. However, things can get ugly when the accelerator is pressed and you do not have a 4 barrel carb.
Therefore, if you need to drive at high speed then get yourself a 4 barrel carburetor.
Conclusion
These were three of the best carburetors for Chevy 350. You should pick one keeping your budget and requirements in mind.
If you a big and powerful carburetor that can control high speeds and acceleration then a 4 barrel Edelbrock 1406 EPS can be a wise option. It has a durable body with corrosion resistance and some amazing features. However, it’s a bit costly.
If you need a budget-friendly option then you can consider Auto Parts Prodigy ROCHESTER 2GC. It’s good for fuel economy and provides good horsepower as well. However, it doesn’t have a choke.
For users looking for the most value, Holley 0-7448 can be the perfect choice. It offers a mix of features and is quite reliable as well.
