Info

Holley just brought EFI within range - It’s perfect for any vehicle that came standard with a 2300 Holley Flange like some Fairlanes, Galaxies, Falcons, Comets, F100s, Javelins, Rebels, Mustangs, Thunderbirds, Cougars and more. It’s economically priced so you can have all the benefits of EFI and still have money to finish or upgrade your ride! It also easily adapts to a square flange or Q-jet flange 4bbl intake with a Mr. Gasket adapter P/N 1933 (4150 Square Flange) or 1929MRG (Spread Bore).

  • Bolt on 2300 Flange Carburetor Replacement

  • Equipped with C4 / C6 Ford transmission kickdown lever as well as TH350, 400 and 700R4 provisions
  • Accepts many common 5 1/8” OEM or aftermarket air cleaner assemblies
  • Throttle body mounted ECU – no extra boxes to mount
  • Integrated ignition timing control
  • Only 4 Wiring Connections Required! (Battery +, Battery -, Switched Ignition & RPM)
  • Internal fuel pressure regulator eliminates the hassle of plumbing an external fuel pressure regulator (Preset to 58.5 PSI)
  • High Resolution Full Color Touchscreen for Initial Setup, Tuning, and Gauge Displays
  • Self-tuning ECU means you don’t have to be a computer/tuning wiz to have EFI!
  • The included Genuine Bosch LSU 4.9 Wideband Oxygen Sensor provides realtime Fuel Map Learn!
  • Included clamp-on oxygen sensor kit for 2.25" exhaust ensures a leak free oxygen sensor installation, with Stainless Steel T-Bolt clamps and a Stainless Steel (Weldable) oxygen sensor flange
