A strong choice for a Chevy 350 balances airflow with the engine’s build and driving needs; for a typical street-focused setup, a 600–650 CFM carburetor is a useful starting point. The Edelbrock AVS2 1906 leads this roundup with 650 CFM, an electric choke, and annular primary boosters, while the 1905 AVS2 offers the same listed airflow with a manual choke. The lineup also includes 500–600 CFM Performer models for milder combinations and 750–800 CFM choices that may better suit engines with greater airflow demands.
Before choosing, verify the carburetor flange, choke preference, fuel system, and engine modifications against your vehicle and intake manifold. The listings do not establish universal compatibility with every Chevy 350 installation.
The Edelbrock AVS2 1906 is the leading choice for a street-oriented Chevy 350 when 650 CFM and an electric choke suit the setup. Its annular primary boosters are listed as improving fuel atomization, and the product data describes smooth throttle response and dependable street performance. The 1905 AVS2 is a close alternative with the same 650 CFM rating but a manual choke.
Engine modifications, intake compatibility, and the driver’s choke preference can change which carburetor is the better match.

#1 · Best Overall
1. Edelbrock AVS2 1906
- Weight: 3.8 lb
- Compatible with Vehicle Type: Car
- Dimensions D x W x H: 4.1"D x 5.5"W x 5.5"H
Best for: Street driving with automatic choke.
Why it ranks #1: Its 650 CFM rating suits a common street-focused starting point, while the electric choke and annular primary boosters add useful everyday features.
Annular primary boosters are the defining feature of the Edelbrock 1906 AVS2, promoting fuel atomization for street use. Its 650 CFM rating, electric choke, and four-barrel layout make it a candidate for a Chevy 350 build when that airflow and automatic choke operation suit the setup.

- Compatible with Vehicle Type: Car
- Dimensions D x W x H: 7.38"D x 13.25"W x 6.75"H
Best for: Manual-choke AVS2 street setup.
Why it ranks #2: It pairs the same 650 CFM rating and annular primary boosters as the top pick with a manual choke for buyers who prefer one.

10. Edelbrock Thunder AVS2 1913
- Weight: 8.8 lb
- Dimensions D x W x H: 7.4"D x 13.4"W x 6.6"H
Best for: 800 CFM AVS2 street builds.
Why it ranks #10: Its 800 CFM rating is the highest in the lineup, making it a specialized option rather than a default match for an otherwise unspecified Chevy 350.
An 800 CFM rating sets the Edelbrock 1913 Thunder Series AVS2 apart from the smaller-flow choices in this roundup. Its square-flange layout and electric choke are also specified, giving Chevy 350 shoppers a high-flow AVS2 option with automatic choke operation.
The 800 CFM rating is the primary decision point for a build that calls for more listed airflow than the 650 CFM AVS2 models.

View on AmazonAvoiding a CFM and Compatibility Mismatch
A carburetor’s CFM rating alone cannot confirm that it will work well with a particular Chevy 350 or bolt onto its intake. This lineup ranges from the 500 CFM Performer 1403 and 550 CFM Performer 1404 to 650 CFM AVS2 models and the 800 CFM Thunder AVS2 That spread makes it important not to treat the largest number as an automatic performance upgrade: engine modifications and intended use matter.
The product listings identify several square-bore designs, but they do not give complete intake-manifold compatibility details for every item. Before purchase, check the intake flange, available clearance, throttle linkage, fuel inlet arrangement, and any vehicle-specific requirements.
Also confirm whether the chosen choke type can be connected and adjusted in your installation. These checks address fit and setup questions that the CFM figures by themselves cannot answer.
Choke Choice and Secondary Design Affect Setup
Choke preference and secondary design can make two similar-capacity carburetors behave differently in day-to-day use and installation. For example, the 650 CFM AVS2 1906 has an electric choke, while the 650 CFM AVS2 1905 uses a manual choke. Among the 600 CFM choices, the Performer 1406 is listed with an electric choke, the 1405 with a manual choke, and the renewed 9906 with vacuum secondary operation and an electric choke.
The 750 CFM Performer 1407 and 1411 both list air-valve secondary designs, with manual and electric chokes respectively. These product details help narrow a shortlist, but they do not establish what wiring, cable routing, linkage, or tuning a specific vehicle requires.
Confirm those installation details for the vehicle and intake rather than assuming a carburetor’s nominal airflow or choke label guarantees a direct fit.
How to Choose an Edelbrock Carb for a Chevy 350
Match CFM to the Engine Setup
Look for a CFM rating that matches the engine’s airflow needs rather than choosing the largest rating by default. These products range from 500 CFM on the Performer 1403 to 800 CFM on the Thunder AVS2 1913, with 550, 600, 650, and 750 CFM options between them. A typical street-focused buyer may begin by comparing the 600 CFM Performer models with the 650 CFM AVS2 choices.
The 500–550 CFM models are the lower-capacity end of this selection, while 750–800 CFM models warrant closer scrutiny of engine modifications and intended use. The product data does not calculate an ideal CFM for an individual engine, so use the engine’s actual configuration and needs to make the final call.
Choose Manual or Electric Choke
Choose the choke type that fits your preference and the vehicle’s available controls and wiring. The 1906 AVS2 is a 650 CFM electric-choke model, while the 1905 AVS2 pairs 650 CFM with a manual choke. At 600 CFM, the Performer 1406 lists an electric choke and the 1405 a manual choke; the 750 CFM Performer 1411 is electric, while the 1407 is manual.
The renewed 9906 also lists an electric choke. Buyers wanting the same listed capacity with a different choke style can compare the 1906 and 1905 directly.
Those preferring a manual control can focus on the manual-choke choices, but should verify cable routing and installation needs for their specific vehicle.
Consider Carburetor Series and Condition
Compare the carburetor series and whether the listing is for a new or renewed unit, since this changes what you are selecting beyond airflow. The AVS2 options include the 650 CFM 1905 and 1906, plus the 800 CFM Thunder AVS2 1913; the product details cite annular primary boosters for the AVS2 series. Performer choices cover 500–750 CFM, with multiple choke configurations.
The 9906 is specifically listed as a remanufactured, renewed Performer with vacuum secondary operation, rather than a new carburetor listing. A buyer prioritizing the described AVS2 booster design can compare the 1906 and 1905, while someone seeking a new Performer can consider the 1405, 1406, or other Performer models.
Confirm the condition and included parts in the listing before ordering.
Which Edelbrock Carb Fits My Chevy 350?
For a street-focused Chevy 350 and an electric choke, start with the Edelbrock AVS2 1906: its 650 CFM rating, annular primary boosters, and listed smooth throttle response make it the strongest all-around fit in this lineup. If you want the same airflow with a manual choke, choose the Edelbrock AVS2 For a 600 CFM option, the Edelbrock Performer 1406 has an electric choke, while the Edelbrock Performer 1405 has a manual choke; the renewed Edelbrock Performer 9906 adds vacuum secondary operation.
Consider the Edelbrock Performer 1404 or Edelbrock Performer 1403 for lower listed airflow, and the 750–800 CFM models only when the engine setup calls for higher capacity. Check manifold and vehicle fit before buying.

Frequently Asked Questions
How do I determine the right CFM for my Chevy 350’s modifications and driving use?
Start with the engine’s modifications and intended use, then compare the listed CFM ratings rather than choosing the largest option by default. The 650 CFM AVS2 models are the leading street-oriented choices here; the 600 CFM options offer alternatives, while 750–800 CFM models make sense only when the setup calls for higher capacity.
Will an Edelbrock square-bore carburetor bolt onto my intake manifold?
Not necessarily; confirm that the carburetor’s flange and mounting pattern match your intake before buying. Product titles identify some models as square bore or square flange, but that alone does not establish compatibility with a specific manifold. Check the intake and carburetor documentation, and verify vehicle fit and any required parts.
What fuel pressure and linkage adjustments are needed after installation?
Use the fuel-pressure specification and adjustment procedure provided for the exact carburetor and engine setup; no single pressure value is established by this lineup. Confirm that throttle and choke linkages move freely through their full range and return correctly. Follow the installation instructions, and have a qualified technician inspect uncertain connections or adjustments.
Should I choose an electric or manual choke for street driving?
Choose based on your preference and how you use the vehicle. The 1906 and 1905 share a 650 CFM rating, but the 1906 has an electric choke and the 1905 a manual choke. The 1406 and 1405 provide the same electric-versus-manual distinction among the listed 600 CFM options.
When should I consider a 750–800 CFM carburetor?
Consider the 750–800 CFM choices only when engine modifications and intended use call for greater capacity. The lineup includes 750 CFM models and an 800 CFM AVS2, but the higher rating alone does not make one the better match for a Chevy Check manifold and vehicle compatibility as well.
Final Words
For a street-focused Chevy 350, start with the AVS2 1906 if its 650 CFM rating and electric choke suit your setup. Choose the 1905 for the same listed airflow with a manual choke. The Performer 1406 and 1405 are 600 CFM alternatives, while higher-capacity models warrant consideration only when your engine setup calls for them.
Before ordering, verify intake-manifold compatibility and vehicle fit.
