Holley 4150 Carburetor on eBay: CFM, Variants & Live Listings
The Holley 4150 is a four-barrel carburetor architecture in continuous production since the 1960s and the most-rebuilt performance carburetor on the secondary market. The 4150 platform spans 600 to 850 CFM across both vacuum-secondary and mechanical (double-pumper) variants, with either electric or manual chokes. Pre-owned 4150s on eBay typically run $220 to $500 depending on the list number, condition, and whether the carburetor ships clean and ready or needs a rebuild kit.
Buying a used 4150 turns on three filters: the right CFM for your engine, the right secondary type for your driving style, and the right choke type for your engine bay. eBay's default search buries those decisions under thousands of unrelated listings — jets, gaskets, accelerator pumps, intake manifolds, and other people's rebuild projects. AuctionMapper's Carburetors category surfaces the eBay aspect filters that actually matter (CFM rating, number of barrels, fuel type), so you can isolate the right list number without scrolling.

AuctionMapper is a free eBay search tool that lets visitors browse all 20,000+ eBay categories without typing a keyword, filter by category-specific attributes eBay doesn't expose (dial color for watches, CFM rating for carburetors, saddle seat size, diecast scale, lens mount), and sort by total cost (price + shipping). When a category is selected, the filter panel adapts to that category's item specifics; when a keyword is searched, the category tree trims to show only branches with matching results. AuctionMapper queries eBay's live inventory through the official Browse API. Founded 2006; rebuilt 2024–2026. It is an eBay Partner Network traffic source — not a competing marketplace — so every outbound click lands on eBay itself.

4150 Market Overview
The Holley 4150 has the deepest used-parts market of any performance carburetor — supply on eBay typically runs hundreds of listings at any given time across the major list numbers. Pricing has stayed flat to slightly lower over the last 24 months as fewer street rebuilds emerge from the 1990s-2000s swap-meet culture.
- Most-listed: List 1850 (600 CFM, vacuum-secondary, manual choke) — the entry-level 4150 for small-block V8s
- Best-value rebuild target: Mid-1980s 3310 (750 CFM vacuum-secondary) — well-supported with rebuild parts
- Highest premium: Genuine first-generation list 4777 / 4779 / 4781 double-pumpers with original choke towers
- Watch for: Modern Ultra-XP, HP, and Brawler variants — different parts compatibility, not always interchangeable with a 4150 rebuild kit
Holley 4150 List Numbers, CFM & Variants
The list number on the choke-tower tag tells you the CFM, secondary type, and choke type. Match it to your engine and driving style:
| List # | CFM | Secondary | Choke | eBay Range |
|---|---|---|---|---|
| 1850 | 600 | Vacuum | Manual | $220-$320 |
| 1850-7 | 600 | Vacuum | Electric | $240-$340 |
| 4777 | 650 | Mechanical | Manual | $280-$420 |
| 3310 | 750 | Vacuum | Manual | $260-$380 |
| 80508 | 750 | Vacuum | Electric | $280-$400 |
| 4779 | 750 | Mechanical | Manual | $300-$450 |
| 4781 | 850 | Mechanical | Manual | $340-$500 |
| 8007 | 390 | Vacuum | Manual | $200-$280 |
Prices reflect typical eBay completed-sale ranges for used carburetors in functional condition with the original choke tower tag. Rebuilt-by-shop carburetors typically command 30-50% premium. Tag-less or visibly-cracked bodies trade well below the range. All prices USD.
How to Find the Right 4150 Using AuctionMapper
eBay's default keyword search returns listings for jets, accelerator pumps, intake manifolds, and other people's rebuild projects when you type "Holley 4150." AuctionMapper's category-aware filters skip past those:
- Search by list number, not nickname
Use "Holley 1850" or "Holley 4777" instead of "Holley 4150" — the list number isolates the exact CFM and variant. Listings without a clear list number are often parts, not whole carbs.
- Select the Carburetors category
Once you select Carburetors, eBay's aspect filters appear: CFM rating, number of barrels, fuel type, brand. AuctionMapper surfaces these in the left filter panel automatically.
- Set a price floor of $150
Anything under $150 is almost always a parts listing (jets, gaskets, fuel bowls). The floor instantly removes them from your results.
- Use the "tag" keyword
Add "tag" to require a clear photo of the choke-tower list-number tag. Tagless listings are often misidentified or stripped.
- Sort by total cost (price + shipping)
Carburetors are heavy and shipping varies — a $250 carb with $35 shipping costs more than a $270 carb with free shipping. AuctionMapper sorts by combined total.
- Use distance sort for local pickup
Local pickup eliminates a $30-$50 freight shipping cost. Sort by distance from your ZIP to find a 4150 you can pick up in person.

Frequently Asked Questions
What CFM Holley 4150 do I need?
A rough rule of thumb: cubic-inch displacement × max RPM ÷ 3,456 = required CFM. For most street small-block V8s (302, 327, 350, 383) running 5,500-6,500 RPM, the 600-750 CFM range covers it. Big-block 454s or aggressive cam packages up to 8,000 RPM start to want 750-850 CFM. Going too big costs throttle response and fuel economy on the street; going too small caps top-end power. The 4150 platform spans 600 (List 1850), 650 (4777), 750 (3310, 80508), and 850 (4781) CFM in vacuum-secondary and double-pumper variants.
Vacuum-secondary vs double-pumper — which 4150 is right?
Vacuum-secondary 4150s (List 1850, 3310, 80508) open the rear barrels based on engine vacuum demand — smoother on the street, better fuel economy, and forgiving on heavy automatic-transmission cars. Double-pumper 4150s (4777, 4779, 4781) open the secondaries mechanically with the throttle linkage — sharper throttle response, better for manual transmissions and lighter cars, but worse fuel economy. Daily-driver street car: vacuum secondary. Track car or aggressive street/strip: double-pumper.
Electric choke vs manual choke 4150?
Electric chokes pull in cold-start enrichment automatically using a heater coil that releases the choke as it warms — fewer cables to route, no driver attention needed. Manual chokes use a cable run to the dashboard, giving you direct control of cold-start mixture. Most modern street rebuilds run electric chokes (cleaner engine bay, less fiddling). Cars with restoration intent often keep manual chokes. The 4150 platform supports both via different baseplate variants.
How can I tell what 4150 list number a carburetor is?
Holley stamps the list number on a small metal tag attached to the choke tower screw on the carburetor body. The list number tells you everything: CFM rating, secondary type (vacuum vs mechanical), choke type, and intended application. Common 4150 list numbers: 1850 (600 CFM vacuum-secondary, manual choke), 3310 (750 CFM vacuum-secondary), 4777 (650 CFM double-pumper), 4779 (750 CFM double-pumper), 4781 (850 CFM double-pumper), 80508 (750 CFM vacuum-secondary, electric choke). When buying used, demand a clear photo of the list-number tag.
Are used Holley 4150s reliable?
Yes — Holley 4150s are some of the most rebuildable carburetors ever made. The 4150 architecture has been continuously produced since the 1960s, and rebuild kits and replacement parts are inexpensive and widely available. A used 4150 in unknown condition typically wants a $30-$60 rebuild kit, fresh gaskets, and a thorough cleaning. The cast bodies rarely fail; throttle shafts, accelerator pumps, and power valves are the common wear points. Skip used carburetors with visible cracked bodies, severely worn throttle shaft bores, or missing tags.
