The Edelbrock 1906 AVS2 with electric choke is the best overall carb for a Chevy 350, offering smooth drivability and modern convenience. For those on a tighter budget or wanting full control, the 1905 AVS2 manual choke version delivers the same solid performance at a lower price. Both are 650 CFM four-barrel carbs with annular boosters, making them ideal for stock to mildly built engines.
Picking the right carburetor isn’t just about bolting on a shiny piece, it’s about matching the right airflow and fuel delivery to your engine’s needs. Too often, people over-carb their 350 and end up with sluggish throttle response and poor low-end torque.
This guide cuts through the noise by focusing on real-world specs and owner experiences to find the best Edelbrock carbs for the most common Chevy 350 builds. I looked at CFM ratings, choke types, and key features like annular boosters and build quality to recommend options that deliver both performance and reliability.

Edelbrock 1906 AVS2 Carburetor Electric Choke
Strengths
- Electric choke
- 650 CFM ideal
- Annular boosters
- Satin finish
- 4 barrel design
Trade-offs
- Higher cost
- More wiring
- Not for purists
The Edelbrock 1906 AVS2 stands out in the carburetor game because it blends modern convenience with classic muscle.

Edelbrock 1905 AVS2 Carburetor 650 CFM
Strengths
- Manual choke
- Easy tuning
- 650 CFM ideal
- Satin finish
- Annular boosters
Trade-offs
- Cold starts harder
- No electric choke
- Requires choke cable
If you want to keep it simple and in control, the Edelbrock 1905 AVS2 is my go-to recommendation for a raw, mechanical feel. No wires, no fuss, just a cable-connected manual choke you operate yourself. That might sound outdated, but for weekend drivers, hot rods, or show cars that live in garages, it’s a reliable, time-tested setup. The 650 CFM flow matches well with performance 350s running headers, hotter cams, and dual-plane intakes.
Reviewers note it tunes easily and holds settings well once dialed in. The annular booster design gives it an edge over older carb designs, delivering a smoother fuel curve and better off-idle response. Compared to the 1906, it’s slightly cheaper and cleaner under the hood, fewer connections, less to go wrong. I’d pick this over the electric version if you value tuning transparency and don’t mind a two-pump start in winter.

How We Tested edelbrock carbs for chevy 350
Rather than a hands-on lab test, my research for these recommendations centered on a detailed comparison of published specifications and features across the Edelbrock AVS2 line. I then weighed owner reviews from forums and retail sites alongside assessments from respected automotive publications. Years spent discussing performance with fellow enthusiasts informs my understanding of what truly matters when selecting a carburetor, and I used that knowledge to evaluate each model.
For a Chevy 350, consistent drivability and reliable performance are key. I prioritized models with properly sized CFM ratings (around 650 for most builds) and the type of choke – electric versus manual – as those impact daily usability. A carburetor’s ability to deliver a consistent air/fuel mixture directly translates to how enjoyable a vehicle is to drive, and that’s what I focused on. You can find more discussion on 350 Chevy carburetors on my site.
Specifications clearly define a carb’s flow rate and choke type, but real-world performance depends on how well it’s received by owners. I paid close attention to feedback regarding ease of tuning, cold starting, and overall reliability. While specs tell you what a carburetor is, owner experiences reveal how it performs in practical applications – and whether it pairs well with other upgrades like a Silverado cold air intake.
Choosing The Right edelbrock carbs for chevy 350
Finding the right carburetor for a Chevy 350 can feel overwhelming, but focusing on a few key aspects will get you pointed in the right direction.
A quality Edelbrock carburetor for a Chevy 350 balances airflow (measured in CFM), fuel delivery, and choke operation. Look for models with annular boosters for improved atomization, a four-barrel design for versatility, and a CFM rating matched to your engine’s horsepower and intended use. Consider the choke type (electric or manual) based on your climate and tuning preference.
CFM and Engine Matching
The Cubic Feet per Minute (CFM) rating is where many people start, and for good reason. It directly impacts how your engine runs. Too little CFM, and you’ll starve the engine for air at higher RPMs. Too much, and you’ll sacrifice low-end torque and fuel economy. For a stock or mildly modified Chevy 350, 600-650 CFM is generally a sweet spot. If you’ve significantly increased horsepower through substantial modifications (camshaft, heads, etc.), you’ll want to move up to a 750 CFM or larger unit. Don’t just guess; consulting engine build sheets or a reliable source for recommended Edelbrock carburetors is always wise.
Choke Type: Electric vs. Manual
This is where personal preference and driving conditions really come into play. Electric chokes are incredibly convenient, especially in varying climates. They automatically adjust to temperature, providing consistent cold starts. Manual chokes, on the other hand, give you ultimate control. They require a bit more finesse to dial in, but allow for precise tuning, which can be beneficial for performance or if you live in a consistently cold environment. I’ve seen many enthusiasts prefer manual chokes for their ability to fine-tune the mixture, but it does demand more attention.
Beyond the Basics: Features and Finish
While CFM and choke type are crucial, don’t overlook the smaller details. Annular boosters, a hallmark of Edelbrock’s AVS2 line, are fantastic for improving fuel atomization and throttle response. The finish is largely aesthetic, but a satin finish is common and durable. More importantly, consider the overall build quality and reputation of the brand. If you’re also looking to upgrade other components on your truck, exploring Silverado 1500 parts can help you maximize your vehicle’s potential.
A properly sized carburetor is like a well-tuned instrument: it doesn’t just make the engine run, it makes it respond.
Here’s a quick breakdown of what to consider when looking at features:
- Adjustability: A secondary adjustment for power valve blow-out is a nice-to-have.
- Metering Block: Look for a removable metering block for easier cleaning and rebuilds.
- Fuel Inlet: A threaded fuel inlet (rather than a press-fit) is more secure and less prone to leaks, especially with modern fuels; this helps prevent issues down the line and makes the carburetor more durable.
