Description

Installation Made Simple

This 350 CFM 2-barrel carburetor is designed for quick and hassle-free installation—just bolt it on, connect the fuel line, and you're ready to go. No complex tuning required for most applications.

Why Upgrade to EVIL ENERGY Carburetors?

1. Broad Compatibility for Seamless Cross-Brand Fitment

• Limited Compatibility Frustrations: Many carburetors are restricted to a single brand (e.g., only GM or only Ford), requiring costly adapters or custom linkage overhauls when swapping between makes—adding time, labor, and unexpected expenses to upgrades.
• EVIL ENERGY Advantage: Our 350 CFM 2-barrel carburetor is designed to work with GM, Chrysler, and Ford automatic transmission kickdown linkages (with additional parts possibly needed for specific setups). This cross-brand compatibility eliminates brand-specific barriers, ensuring a smoother integration across major makes and reducing the complexity of linkage adjustments compared to strictly single-brand carburetors.

2. Brand-New Construction vs. Unreliable Remanufactured Units

• Remanufactured Risks: Rebuilt carburetors often reuse worn jets, valves, or gaskets, hiding internal fatigue that leads to inconsistent fuel delivery, leaks, or sudden failure—especially under high-RPM stress.
• EVIL ENERGY Assurance: 100% new components with zero recycled parts ensure long-term reliability. Every detail, from the #63 jets to the 8.5 Hg power valve, is fresh and precision-engineered, avoiding the hidden flaws of remanufactured alternatives.

3. Tuned for Responsiveness and Low-End Power

• Generic Carburetor Shortcomings: Budget carburetors lack calibrated tuning, causing sluggish throttle response, rough idle, or weak low-end torque—critical flaws for daily drivers or street performance builds.
• EVIL ENERGY Edge:
  ✓ Pre-calibrated #63 main jets and 0.028-inch accelerator pump nozzle for precise air-fuel mixture
  ✓ 30cc accelerator pump delivers instant fuel on demand, eliminating lag during quick throttle inputs
  ✓ 8.5 Hg power valve enhances low-RPM torque, making it ideal for both city driving and light performance use
  ✓ 1.21-inch venturi and 1.5-inch throttle bore balance airflow for stable high-RPM performance

4. Unbeatable Value Without Sacrificing Quality

• Premium Pricing Burden: Top-tier carburetors (like Holley 0-80350) cost over $579.95, forcing enthusiasts to choose between performance and budget—often delaying upgrades or settling for inferior parts.
• EVIL ENERGY Savings: Priced at just $399.99 (over 30% less than competitors), it delivers comparable performance without the premium. You get a precision-tuned, brand-new carburetor that matches the reliability of higher-priced options—proving value and quality can coexist.

5. Plug-and-Play Installation for DIY Enthusiasts

• Complex Upgrade Headaches: Many performance carburetors require professional tuning, specialized tools, or linkage modifications—adding hours of work and professional labor costs that inflate the total upgrade expense.
• EVIL ENERGY Simplicity: Designed for hassle-free installation: bolt it on, connect the fuel line, and go. No complex tuning is needed for most applications, thanks to pre-calibration and wet-flow testing. Even with GM overdrive transmissions (TH700R4/TH200R4), required brackets are straightforward to add—making it perfect for weekend builders or first-time upgraders.
