1. Edelbrock Performer 1406: Best Overall
In our evaluation of the best Edelbrock carburetors for Chevy 350, the Performer 1406 stands out as the top pick for most owners. Based on manufacturer specs, this 600 CFM carburetor is designed for stock to mild performance small-blocks, offering an electric choke for convenience and manual secondaries for driver control. Aggregated owner feedback highlights its straightforward installation and reliable operation, making it a favorite for restoration projects or daily drivers.
However, the manual secondary can feel less progressive compared to vacuum-operated carbs, and some enthusiasts prefer a more aggressive tune. If you have a heavily modified 350, consider a higher CFM model. But for a balanced, reliable upgrade, the 1406 is hard to beat.
- 600 CFM flow rate ideal for stock to mildly modified 350 engines
- Electric choke provides reliable cold starts without manual adjustment
- Durable aluminum construction with a proven track record from owner feedback
Pros: Easy bolt-on installation with no major modifications needed; Smooth throttle response and reliable idle out of the box
Cons: Manual secondary can be less responsive than vacuum secondary for some builds
2. Edelbrock Performer 1407: Best for Mild Performance
The Edelbrock Performer 1407 is our pick for mild performance builds. With 750 CFM, it delivers more airflow than the 1406, making it suitable for engines with aftermarket intakes, headers, or mild cams. Owner feedback indicates that it provides a noticeable power increase when matched with proper modifications, and the electric choke simplifies daily use.
That said, on a bone-stock Chevy 350, the 750 CFM can lead to a slight loss of low-end torque and potential drivability issues. We recommend this carb only if your engine has supporting upgrades. If your 350 is mostly stock, the 1406 is a better match.
- 750 CFM capacity suits mild to moderately modified 350 engines
- Electric choke ensures easy starting in varying temperatures
- Aluminum body with a reputation for consistent performance based on owner reviews
Pros: Increased airflow supports cam upgrades and headers; Tuneable metering rods allow fine adjustments
Cons: May be too much carb for a stock 350 without supporting mods
3. Edelbrock AVS2 1906: Best for Street Performance
The Edelbrock AVS2 1906 introduces annular flow boosters for improved fuel atomization, which we found to enhance throttle response and fuel economy based on manufacturer claims and owner reports. The vacuum secondary automatically opens based on engine load, making it very street-friendly. For a daily-driven Chevy 350, this carb offers a great balance of performance and drivability.
However, some owners noted that the annular boosters require stable fuel pressure; a low or fluctuating pressure can cause hesitation. If your fuel system is stock or aging, you may need a fuel pressure regulator. Also, the 650 CFM may not satisfy high-horsepower builds.
- 650 CFM with annular flow boosters for better fuel atomization
- Vacuum secondary automatically adjusts to engine demand
- Electric choke for reliable cold starts
Pros: Smooth transition from idle to full throttle; Improved fuel efficiency compared to manual secondary carbs
Cons: Annular boosters can be sensitive to fuel pressure
4. Edelbrock AVS2 1910: Best for Tuning Flexibility
For enthusiasts with a built Chevy 350, the Edelbrock AVS2 1910 offers 800 CFM and extensive tuning options. The vacuum secondary can be adjusted with different springs, and the annular boosters provide excellent atomization. Owner feedback from track users indicates strong top-end performance when the engine can use the airflow.
However, this carb is not for everyone. On a stock 350, it will likely cause drivability issues and poor fuel economy. We recommend it only for engines with aggressive cams, high-flow heads, and intakes. If your build is milder, stick with a 650 or 750 CFM model.
- 800 CFM capacity for high-performance or stroker 350 engines
- Vacuum secondary with adjustable spring for tuning
- Annular boosters for precise fuel metering
Pros: Supports high-RPM power on built engines; Tunable secondary spring for custom response
Cons: Overkill for stock or mild 350 builds, can hurt low-end torque
5. Edelbrock Thunder Series AVS 650: Best for Classic Look
The Edelbrock Thunder Series AVS 650 combines the proven 650 CFM performance with a polished finish that looks great on a classic Chevy 350. Based on owner reviews, it delivers similar drivability to the standard AVS2 but with added visual appeal. The vacuum secondary and electric choke make it a convenient choice for street use.
That said, the polished surface is prone to tarnishing and requires regular cleaning to maintain its shine. If you prioritize function over form, the standard Performer or AVS2 offers the same performance at a lower cost. This carb is best for show cars or owners who want a shiny engine bay.
- Polished aluminum finish for a classic engine bay appearance
- Vacuum secondary for automatic adjustment
- Same reliable internals as the Performer series
Pros: Aesthetic appeal with a shiny, show-quality finish; Good performance for mild street builds
Cons: Polished surface shows fingerprints and requires maintenance
6. Edelbrock Performer EPS 1405: Best Budget Option
The Edelbrock Performer EPS 1405 is the budget-friendly option in our lineup. It offers the same 600 CFM flow as the 1406 but with a manual choke. Owner feedback indicates it works well for warm climates or owners who don’t mind pulling a choke cable. The manual secondary keeps the design simple and reliable.
However, the manual choke is a dealbreaker for many daily drivers, especially in colder regions. If you want hassle-free starting, spend a little more for the 1406. This carb is best for budget builds or vehicles used in mild weather where choke operation is not a major concern.
- 600 CFM for stock 350 engines
- Manual choke requires driver input for cold starts
- Simple design with fewer parts for easy rebuilding
Pros: Lower cost than electric choke models; Reliable mechanical operation with less electronics
Cons: Manual choke can be inconvenient in cold weather
7. Edelbrock AVS2 1806: Best for Off-Road
The Edelbrock AVS2 1806 is a 500 CFM carb designed for off-road use. Based on manufacturer specs, it prioritizes low-end torque and throttle response on uneven terrain, making it suitable for 4×4 Chevy 350s. The vacuum secondary helps prevent bogging when hitting bumps, and the electric choke aids in cold starts at altitude.
However, the 500 CFM rating significantly restricts high-RPM power, so it is not ideal for highway driving or racing. If your Chevy 350 spends most of its time on pavement, a larger carb will perform better. This carb is best for dedicated off-road vehicles where low-speed control matters more than peak horsepower.
- 500 CFM for lower RPM torque in off-road applications
- Electric choke for easy starts in varied conditions
- Vacuum secondary to prevent bogging on rough terrain
Pros: Better low-end torque for crawling and trail driving; Tuned for durability in dusty environments
Cons: 500 CFM limits top-end power on the highway
Frequently Asked Questions
What CFM Edelbrock carb is best for a stock Chevy 350?
For a stock Chevy 350, a 600 CFM carburetor like the Edelbrock Performer 1406 is ideal. It matches the engine’s airflow needs and provides good throttle response without overwhelming the induction system. Larger CFM can cause drivability issues on an unmodified engine.
Can I use an Edelbrock carb on a Chevy 350 with an aftermarket intake manifold?
Yes, Edelbrock carbs are designed to work with most aftermarket intake manifolds. However, you must ensure the carburetor’s mounting flange matches the intake (square bore or spread bore). Most Edelbrock carbs are square bore, which fits Edelbrock and many other intakes.
What is the difference between manual and electric choke on an Edelbrock carb?
An electric choke automatically adjusts the choke plate based on engine temperature, requiring no driver input. A manual choke requires a cable and the driver to pull and push it. Electric chokes are more convenient for daily driving, while manual chokes are simpler and often preferred for off-road or race applications.
How do I tune an Edelbrock carb for my Chevy 350?
Basic tuning involves adjusting the idle mixture screws, setting the idle speed, and potentially changing metering rods and jets. Edelbrock provides tuning kits and guides. Many owners find the carb runs well out of the box, but fine-tuning can optimize performance for your specific engine and altitude.
Are Edelbrock carbs compatible with E85 fuel?
Standard Edelbrock carbs are not calibrated for E85, which requires different jetting and materials to resist corrosion. Edelbrock offers E85-specific models, or you can convert a standard carb with a rebuild kit designed for E85. Using E85 in a standard carb can damage seals and cause poor drivability.
