Evil Energy STREET 650 CFM 4-Barrel Carburetor Electric Choke Mechanical Secondary

A purpose-built 4-barrel carburetor engineered as a performance upgrade for stock to mildly modified V-8 engines, striking the perfect balance between daily usability and spirited driving. With 650 CFM airflow, it delivers consistent air-fuel mixture to meet the demands of street use—whether commuting, cruising, or overtaking—ensuring reliable power across all RPM ranges.

Designed for responsiveness, it features a mechanical secondary throttle that opens in sync with throttle position, eliminating lag and providing immediate acceleration—ideal for street scenarios where quick power delivery matters. The factory preset electric choke adjusts automatically to temperature, ensuring easy startups in varying climates (no manual tuning needed), while the single feed fuel inlet simplifies installation, reducing the hassle of complex fuel line setups.

Calibrated for excellent street performance right out of the box, it comes pre-tuned with #70 main jets, #74 secondary jets, a 0.031-inch accelerator pump nozzle, and a 6.5Hg power valve—no extensive post-installation adjustments required for most setups. It also includes practical upgrades: changeable air bleeds and adjustable needle and seats, allowing for fine-tuning to match specific engine mods (e.g., intake or exhaust upgrades) if needed.

Built entirely from new components (no remanufactured parts), it boasts a square bore flange, 3.25-inch compact height, and integrated 700R4/200R4 transmission kickdown cable mounting—streamlining linkage setup for compatible transmissions. Designed for flexible fitment, it works with GM, Ford, and Chrysler automatic transmission shift linkages (note: specific setups may require additional fitment parts) and fits most standard intake manifolds, making it a versatile upgrade for street builds.

Why Choose Evil Energy STREET 650 CFM Carburetor?

• Outstanding Value with Comparable Performance: The 650 CFM Brawler Diecast Carburetor is priced at $499.95, while our carburetor is available for less than $379.99. Both offer core features like 650 CFM airflow, mechanical secondaries, and electric choke—we deliver the same street performance at over $120 in savings.
• Mechanical Secondaries for Responsive Street Driving: Unlike vacuum-operated secondaries that may lag, mechanical secondaries open directly with throttle position. This ensures immediate acceleration, making it ideal for street scenarios like merging or overtaking.
• Ready-to-Use Out of the Box: Pre-calibrated with #70/#74 jets, a 0.031-inch accelerator nozzle, and a 6.5Hg power valve, it requires minimal tuning after installation. Most users can install and drive immediately, saving time and effort.
• 100% New Construction for Long-Term Reliability: Built entirely from new components (no reused parts), it avoids the hidden wear risks of remanufactured units. This ensures consistent performance and reduces the chance of leaks or early failure, even with regular use.
• Flexible Fitment Across Brands: Designed to work with GM, Ford, and Chrysler automatic transmission shift linkages (with possible additional parts for specific setups), it fits most standard square bore intake manifolds. This flexibility reduces the need for custom adapters, simplifying installation across different vehicles.
• Practical Electric Choke for Daily Use: The electric choke adjusts automatically to temperature, ensuring reliable cold starts in winter or cool mornings—no manual adjustment needed. This makes it highly convenient for daily drivers.

FAQs About Evil Energy STREET 650 CFM 4-Barrel Carburetor

1. What makes this carburetor suitable for street use?
It balances performance and practicality: mechanical secondaries provide responsive acceleration for street scenarios, while the electric choke ensures easy cold starts—critical for daily driving. The 650 CFM airflow is also optimized for street engines, avoiding "over-carbing" issues.

2. Is it compatible with my vehicle?
It works with GM, Ford, and Chrysler vehicles with automatic transmission shift linkages. As with most universal carburetors, specific setups (e.g., unique linkage or intake manifolds) may require additional fitment parts—we recommend checking your vehicle’s specifications first.

3. Do I need to tune it after installation?
It comes pre-calibrated for street use, so most users won’t need extensive tuning. Minor adjustments (e.g., idle speed) may be needed for highly modified engines, but it’s ready to use for most daily or mild performance setups.

4. Why choose mechanical secondaries over vacuum-operated ones?
Mechanical secondaries open directly with the throttle, providing immediate power—great for street driving where quick acceleration (e.g., merging, passing) is needed. Vacuum-operated secondaries are smoother but may have slight lag, making mechanical ones better for responsive street use.

5. Is this carburetor remanufactured?
No. It’s constructed entirely from new components, with no reused parts. This ensures consistent quality and reduces the risk of hidden wear, which is important for reliable daily use.

6. Will it fit in a tight engine bay?
With a height of 3.25 inches, it has a compact profile that fits most standard street engine bays, including classic cars or modified vehicles with limited space. We recommend measuring the available space (from intake manifold to hood) to confirm fitment.

7. Does it require a fuel return line?
No. It features a single fuel inlet and is designed to work with standard non-return fuel systems, simplifying installation for most street vehicles.
