This 4-barrel carburetor is ideal for small-block applications such as the Ford F-250 (390ci) or the Chevrolet LG4 (305ci). It comes pre-calibrated with #86 primary jets and #95 secondaries, delivering consistent airflow and throttle response for everyday driving or light performance use.

Key specifications

  • 500 CFM airflow for optimized fuel delivery on small-block V8s
  • Square-bore 4-barrel configuration for easy bolt-on compatibility
  • Mechanical secondaries for responsive acceleration
  • Manual choke for cold-start control and tuning flexibility
  • Compact 3.25-inch height to fit tight engine compartments
  • Suitable for classic sedans, trucks, and muscle cars

At just $329.99, this 500 CFM carburetor delivers exceptional value compared to the Edelbrock 1404 priced at $457.95. Whether you're upgrading a daily driver or completing a vintage restoration, EVIL ENERGY offers the performance, compatibility, and price point to meet your needs.

Description

This 500 CFM 4-barrel carburetor is engineered for consistency, durability, and easy tuning. Unlike traditional designs, it's unaffected by engine backfires—there are no power valves to blow out, and the metering rods can be swapped in seconds without removing the carburetor or draining fuel.

Once tuned, the carburetor 'holds a tune', meaning your calibration stays locked in for consistent long-term performance—no frequent readjustments needed. Compared to conventional carburetors, this design offers superior stability under varying conditions.

The lightweight all-aluminum, two-piece body resists warping and is compatible with gasohol and blended fuels, offering long-lasting reliability. Simple tub-style float bowls, rear-pivot floats, and a clean layout make it extremely user-friendly and easy to service, ideal for both daily use and mild performance setups.

Installation is simple—just bolt it on with no special tools required. This carburetor is compatible with the Edelbrock 2114 intake manifold, and works well in:

  • 1975 Ford F-250 with a 390ci V8 and manual transmission
  • Chevy LG4 305ci small-block engines
  • Mild-performance builds, dual four-wheel drive setups, and small-CID street trucks
