EVIL ENERGY 600 CFM 4-barrel Carburetor Electric Choke Air Valve-Controlled Secondary

The EVIL ENERGY 600 CFM 4-barrel carburetor is designed for drivers who want consistent street performance, smooth throttle response, and long-term reliability. Unlike many traditional 600 carb models, including the Edelbrock 600 Carburetor (1406), the EVIL ENERGY Carburetor uses a metering rod fuel control system rather than a power valve. This means the EVIL ENERGY 600 Carburetor is unaffected by engine backfires—there are no power valves to blow out, ensuring dependable operation and reduced maintenance.

Because the metering rods can be swapped without removing the 4-barrel carburetor or draining fuel, tuning is fast and straightforward. Once tuned, the 600 CFM carburetor maintains its calibration over time, eliminating the constant re-adjusting that many street and classic V8 owners experience with older carb designs. The result is stable idle quality, clean acceleration, and reliable power delivery across the RPM range.

Crafted from lightweight, corrosion-resistant aluminum, the EVIL ENERGY Carburetor also offers improved heat resistance and long service life, making it ideal for daily street driving, weekend cruising, and classic restoration builds. Its precise fuel metering, smooth transitions, and consistent airflow make the EVIL ENERGY 600 CFM 4-barrel carburetor a strong value alternative to Edelbrock’s 1406—offering comparable performance at a more affordable price.

Key Performance Features of the 600 carburetor

• All-Aluminum Two-Piece Construction
  The EVIL ENERGY 600 Carburetor uses a lightweight all-aluminum two-piece body that reduces engine load and resists heat distortion. This ensures long-lasting reliability compared to older cast designs. Ideal for drivers wanting a strong, durable 600 CFM carburetor for daily and performance use.
• Air Valve-Controlled Secondaries
  Unlike harsh mechanical secondary systems, this 4-barrel carburetor features air valve-operated secondaries that open smoothly based on engine demand. That means no bogging, no sudden surges—just clean, predictable acceleration for street, cruising, and moderate performance builds.
• Fuel-Compatible Design for Modern Drivers
  The EVIL ENERGY Carburetor is compatible with gasohol and blended pump fuels (E10/E15), preventing corrosion and wear. This gives it an advantage over older 600 carb setups that struggle with today’s ethanol-blended gasoline.
• Simple, Serviceable Layout
  Tub-style bowls and rear-pivot floats make cleaning, tuning, and jet adjustments easy—whether you're a DIY tuner or a workshop tech. Designed for owners who want a 600 CFM 4-barrel carburetor that is straightforward to maintain.
• Fuel-Efficient Performance Calibration
  Factory-set with #98 primary jets and 0.075-inch x 0.047-inch metering rods, the EVIL ENERGY 600 Carburetor balances power, throttle response, and fuel efficiency—perfect for daily commuting, smooth idle, and weekend cruising.

FAQs – EVIL ENERGY 650 CFM 4-Barrel Carburetor

Q1: Is a 650 CFM carburetor good for my vehicle?
A1: Yes. A 650 CFM Carburetor is ideal for small-block V8 engines (such as 302, 350, 383, 400) producing 300–450 HP. The EVIL ENERGY 650 Carburetor offers strong throttle response for daily street driving and enough airflow for weekend performance use.

Q2: What does 650 CFM mean for performance?
A2: CFM represents airflow capacity. A 650 CFM carb provides the optimal air-fuel flow balance for most street-performance V8s—preventing low-RPM richness and avoiding airflow restriction at high RPM.

Q3: Does this carburetor use vacuum or mechanical secondaries?
A3: This is a mechanical secondary carburetor, meaning the secondaries open based on throttle input—not engine vacuum. This ensures instant power delivery, making the EVIL ENERGY 650 Carburetor excellent for spirited driving and acceleration.

Q4: Will this 650 4 barrel carburetor fit my intake manifold?
A4: Yes. The EVIL ENERGY 650 CFM Carburetor uses a square-bore flange, fitting most GM, Ford, and Chrysler performance intake manifolds. Just confirm your manifold is square-bore, not spread-bore.

Q5: Does the EVIL ENERGY Carburetor include an electric choke?
A5: Yes. It features an electric choke for automatic cold-starts—ideal for daily drivers and colder climates.

Q6: Is tuning required after installation?
A6: The EVIL ENERGY 650 CFM 4-Barrel Carburetor is pre-calibrated for most street engines. Minor idle and mixture adjustments may be needed for modified camshafts or aftermarket heads, but no full re-jetting is typically required.

Q7: Can this replace a Holley 650 carb or Edelbrock 650 carburetor?
A7: Yes. It is a direct alternative to the Holley 650 carb (0-1850S) and Edelbrock 650 series models—offering the same core performance, but at a more affordable price.

Q8: What fuels is it compatible with?
A8: The EVIL ENERGY Carburetor is compatible with pump gas, E10/E15 gasohol, and blended fuels, with corrosion-resistant aluminum construction for long-term reliability.

Q9: Does it require more maintenance than EFI?
A9: Yes. Like all carburetors, periodic float, jet, and gasket checks ensure peak efficiency. However, the EVIL ENERGY 650 Carburetor is designed for easy servicing.

Q10: Why choose a mechanical secondary 650 CFM carb over a larger 750?
A10: For most street V8s, a 650 CFM carburetor delivers better idle stability, cruising efficiency, and throttle response than an oversized 750. More airflow does not always mean more power.
