The Ford 302, also known as the 5.0L Windsor, is among the most rebuilt and modified small blocks ever made, and the carburetor you bolt on top of it makes or breaks how it idles, cruises, and pulls. A stock 302 makes around 220 to 300 cubic feet per minute of demand depending on cam and compression, so a carb sized between 500 and 650 CFM is the sweet spot for most street builds. Go too big and you lose throttle response and low-end punch. Go too small and you cap top-end power.
We pulled together seven carburetors that genuinely fit the Ford 302 and that real builders run every day, from the famously easy Edelbrock Performer to the track-bred Holley double pumpers. Every pick below works with a standard square-bore intake manifold, the most common setup on a 302. We focused on tuning ease, out-of-the-box driveability, and how each one behaves on a stock or mildly cammed engine, because that is what most 302 owners are actually building.

1. Edelbrock 1406 Performer 600 CFM Carburetor: Best Overall
If you want one carburetor that simply works on a Ford 302, the Edelbrock 1406 is the answer most experienced builders give. The 600 CFM rating lands right in the middle of what a stock or lightly cammed 302 wants, and the electric choke means it fires up cold without you babysitting a manual lever. It comes pre-calibrated on the lean side, so a fresh 302 with a clean fuel system usually idles smooth and cruises efficiently the day you install it.
The real strength here is the tuning system. Edelbrock uses metering rods and jets instead of a power valve, so you can richen or lean the carb in minutes with the engine running and no gaskets to replace. The honest weakness is that this is a calibrated street carb, not a race piece. If you have built a high compression, big cam 302 that screams past 6,500 RPM, the 1406 will start to feel restrictive and you will want a more aggressive double pumper from the list below.
- 600 CFM rating ideal for a stock or mildly modified Ford 302
- Electric choke for reliable cold starts with no manual adjustment
- Calibrated lean from the factory for better fuel economy on the street
Pros: Bolts on and runs with almost no tuning out of the box; Simple metering rod and jet system anyone can adjust; No accelerator pump diaphragm or power valve to fail
Cons: Not aggressive enough for a heavily built race 302; Aluminum body can be fussy about over-tightened fuel fittings
2. Holley 0-1850 Street 600 CFM 4-Barrel Carburetor: Best Holley for Street
The Holley 0-1850 is arguably the most installed performance carburetor in Ford history, and it suits the 302 perfectly. At 600 CFM with vacuum secondaries, it gives you crisp throttle response off idle while the secondaries open only when the engine actually demands air, which keeps a 302 driveable in traffic. Decades of Mustangs, F-100s, and street rods have run this exact carb, so the knowledge base behind it is enormous.
Because the Holley platform is so modular, you can tune it endlessly with jets, power valves, and squirter changes, and parts are available anywhere. The trade-off is that the 0-1850 ships with a manual choke, so you will need to route a choke cable into the cabin or swap to an electric choke kit. Beginners should also learn to protect the power valve, since an unprotected one can blow on a hard backfire and cause a sudden rich condition.
- Legendary 0-1850 platform with decades of proven 302 use
- Vacuum secondaries open progressively for smooth street manners
- Single fuel inlet keeps plumbing simple on a stock 302
Pros: Huge aftermarket parts and tuning support; Vacuum secondaries forgive an oversized carb on a small engine; Time-evaluated center hung float bowls hold tune well
Cons: Manual choke needs a cable run to the cabin; Power valve can blow on a backfire if not protected
3. Edelbrock 1405 Performer 600 CFM Manual Choke Carburetor: Best for Carbon Carb Swaps
The Edelbrock 1405 is the 1406’s twin, with one key difference: it uses a manual choke instead of an electric one. For a 302 living in a hot rod, a vintage truck, or any build where you do not have a clean switched 12-volt source, the manual choke is actually the better choice because there is nothing to wire and nothing electrical to fail. You get the same well-mannered 600 CFM Performer body that has earned its reputation on the small-block Ford.
Tuning is identical to the 1406, with metering rods and jets you can change in minutes, and the dual fuel inlets give you flexibility on fuel line routing. The only real downside is the learning curve of the manual choke itself. On a cold morning you have to set it by hand and back it off as the engine warms, which takes a few starts to get a feel for. Once you have the routine down, it is genuinely a non-issue.
- Same 600 CFM Performer body without the electric choke wiring
- Manual choke preferred for hot rods with no clean 12V source
- Dual fuel inlets accept a wider range of fuel line setups
Pros: No electrical hookup required, ideal for stripped down builds; Identical easy metering rod tuning as the 1406; Strong cold-weather control with a manual choke
Cons: Manual choke takes practice to set on cold mornings; Slightly less convenient than the electric choke 1406 for daily use
4. Holley 0-80457S 600 CFM Electric Choke 4-Barrel Carburetor: Best Balanced Pick
The Holley 0-80457S takes the proven 600 CFM Holley street platform and adds an electric choke plus dual feed fuel bowls, which makes it a smart middle ground for a 302 owner who wants Holley tuning without the manual choke chore. The vacuum secondaries keep it docile around town, and the dual feed bowls feed both float chambers directly, so fuel delivery stays stable when you launch hard or corner aggressively.
This is the carb to grab if you like the Holley ecosystem but want modern convenience. It idles and cruises nicely on a stock 302 and still has the headroom for a mild cam and headers. The catch is that the dual feed plumbing and the electric choke both ask a little more of you at install time, since you need a properly routed fuel log and a switched 12-volt wire. For builders comfortable with basic wiring, that is a minor price for the added stability.
- Holley reliability with the convenience of an electric choke
- Vacuum secondaries tuned for street and light strip duty
- Dual feed fuel bowls for steady float levels under hard launches
Pros: Electric choke removes the manual choke hassle of the 0-1850; Dual feed bowls handle aggressive driving better; Wide tuning support like every Holley platform
Cons: Electric choke needs a switched 12V source wired in; Slightly more complex plumbing than a single feed carb
5. Quick Fuel Technology Slayer SL-600-VS 600 CFM Carburetor: Best Value Performance
Quick Fuel built the Slayer series to give you a Holley-compatible carburetor with a few meaningful upgrades, and the SL-600-VS is a strong fit for a 302 that has moved past stock. The standout feature is four corner idle, which lets you dial in the idle mixture at all four throttle blades. On a 302 with a choppy performance cam, that extra control makes the difference between a rough, stumbling idle and a clean one.
The billet aluminum metering blocks are more durable than stamped parts and hold their calibration over time, and the vacuum secondaries with an electric choke keep the carb friendly for daily street driving. The honest drawback is support. Quick Fuel is well respected but does not have the sheer parts availability of Holley or Edelbrock, so in a pinch at a small-town parts store you may not find Slayer-specific bits on the shelf. Plan your tuning parts ahead and this carb rewards you.
- Holley-style design with upgraded billet aluminum metering blocks
- Four corner idle for a smoother idle on cammed 302 builds
- Electric choke and vacuum secondaries for easy street use
Pros: Four corner idle helps tame a lumpy cam; Quality billet metering blocks resist warping; Drops onto any square bore 302 intake
Cons: Smaller dealer network than Holley or Edelbrock; Needs a switched 12V source for the electric choke
6. Holley 0-80508S 750 CFM Double Pumper 4-Barrel Carburetor: Best for Built 302s
When a 302 has been pushed well past stock with high compression, a big cam, and a free-flowing intake, a 600 CFM street carb starts to feel like a cap on power. That is where the Holley 0-80508S double pumper earns its place. The mechanical secondaries and dual accelerator pumps deliver instant fuel the moment you stab the throttle, which is exactly what a built, high-revving 302 wants for hard launches and strong top-end pull.
This is a focused performance piece, and you should treat it as one. At 750 CFM with mechanical secondaries, it is genuinely too much carburetor for a stock 302 and will make a mild engine soggy and hard to drive at low speed. It also runs a manual choke and a richer calibration that costs you fuel economy. But on the right combination, a stroked or seriously worked 302, this carb wakes the engine up in a way no vacuum secondary unit can match.
- Mechanical double pumper for instant throttle response
- 750 CFM for a high compression, big cam 302 that revs hard
- Dual accelerator pumps eliminate the bog on aggressive launches
Pros: Razor sharp throttle response for performance builds; Ideal for a 302 stroked or heavily cammed; Classic double pumper proven on the strip
Cons: Too much carb for a stock 302, hurts low-end driveability; Manual choke and thirstier calibration for daily driving
7. Edelbrock 1411 Performer 750 CFM Carburetor: Best Big CFM Street Carb
The Edelbrock 1411 is for the builder who wants more airflow than a 600 CFM carb but is not ready to give up the easy street manners of the Performer line. At 750 CFM with vacuum secondaries and an electric choke, it bridges the gap between a docile street carb and a full race double pumper. On a stroked 302 or one with serious head and cam work, the extra CFM lets the engine breathe at the top without the harshness of mechanical secondaries.
It keeps the same metering rod tuning system as its smaller siblings, so adjustments stay simple and there is no power valve to worry about. The thing to be honest about is size. On a stock or only mildly modified 302, 750 CFM is more than the engine can use, and you will feel a softer low-end and slightly worse fuel economy. Match it to an engine that actually demands the air and it is a smooth, easy-living big carburetor.
- 750 CFM with the easy-tuning Edelbrock Performer design
- Electric choke and vacuum secondaries keep it street friendly
- Same metering rod system as the smaller Performers
Pros: More airflow for a stroked or worked 302 that stays streetable; Forgiving vacuum secondaries despite the larger CFM; No power valve to blow and simple to tune
Cons: Oversized for a stock 302, soft low-end response; Larger CFM can hurt fuel economy on a mild engine
Frequently Asked Questions
What size carburetor is best for a Ford 302?
For most Ford 302 builds, a 600 CFM carburetor is the sweet spot. A stock or mildly modified 302 only demands roughly 300 to 350 CFM at peak, and a 600 CFM unit with vacuum secondaries gives you headroom without killing throttle response. Step up to 650 or even 750 CFM only if you have added high compression, a big aftermarket cam, ported heads, and a performance intake. Going too large on a stock engine causes a lazy low-end, poor fuel economy, and a stumble off idle, so resist the urge to over-carb a street 302.
Should I choose vacuum or mechanical secondaries for my 302?
For a street-driven 302, vacuum secondaries are almost always the better choice. They open progressively based on engine demand, which makes the carb forgiving, smooth in traffic, and tolerant of being slightly oversized. Mechanical secondaries, found on double pumper carbs, open directly with the throttle linkage and deliver an instant hit of fuel, which is fantastic on a built, high-revving race engine but harsh and thirsty on a mild street motor. Unless your 302 is heavily modified for strip use, go with vacuum secondaries.
Is an Edelbrock or a Holley carburetor better for a 302?
Both are excellent, and the right pick depends on your priorities. Edelbrock Performer carbs are prized for bolting on and running with almost no tuning, thanks to a simple metering rod system and no power valve to fail, which makes them great for beginners and clean street builds. Holley carbs offer the deepest aftermarket parts support and the widest tuning range, so serious tuners and racers often prefer them. For a first carb on a street 302, the Edelbrock is the easiest path. For maximum tunability, the Holley wins.
Do I need an electric or manual choke on a Ford 302?
It comes down to your wiring and how you drive. An electric choke is more convenient because it opens automatically as the engine warms and requires no input from you, but it needs a switched 12-volt source that is hot only when the key is on. A manual choke needs no electrical connection at all, which suits hot rods and vintage builds without a clean power source, but you have to set and release it by hand on cold starts. If your 302 has reliable switched power available, the electric choke is the easier daily option.
Will these carburetors bolt onto my stock 302 intake manifold?
Yes, every carburetor on this list uses the standard square-bore flange, which is the most common pattern on Ford 302 intake manifolds. As long as your intake is a square-bore four-barrel design, these carbs bolt right on with a standard carburetor gasket. If you happen to have a spread-bore intake, you would need an adapter plate or a different manifold. Always confirm your throttle linkage, fuel line fitting size, and transmission kickdown setup match the new carb, since those details vary between Ford applications and model years.
Our Verdict
For the vast majority of Ford 302 owners, the Edelbrock 1406 Performer is our top pick because it bolts on, fires up cold thanks to the electric choke, and idles and cruises beautifully with almost no tuning, all while being the easiest carb on this list to adjust. Our runner up is the Holley 0-1850, the legendary 600 CFM platform that has powered small-block Fords for decades and offers unmatched parts support for anyone who loves to tune. Choose the Edelbrock for plug-and-play simplicity and the Holley for endless adjustability, and step up to a 750 CFM double pumper only if your 302 is genuinely built for the strip.
