ACES Fuel Injection Royal Flush EFI/CDI Master Kit for Ford 351W Engines

Make your Ford 351W engine a menace on the streets and tracks with the ACES Fuel Injection EFI and CDI master kit! Part of the Royal Flush series, this kit combines a four-barrel throttle body with four 100 lb/hr fuel injectors. While the ECU consistently manages inputs and outputs, the throttle body then ensures you can monitor pressure and air temperature via its built-in sensors. By separating the two, it leads to less engine and vibration exposure for lasting performance with minimal wear. Choose from either a roguish black or clean polished finish to match your engine bay style.

Features and Benefits:
- Fits most 4150-flange, 4-barrel intake manifolds

The kit includes a High Roller DCDI, which offers two-step rev limiter settings for burnout and launch RPM control. It gives drivers the highest spark energy available, resulting in complete combustion no matter the rough conditions. The Blackjack Pro distributor then ensures stability up to a spectacular 10,000 RPM. You even get a 255-LPH, gravity-fed fuel pump alongside a fuel pressure regulator, 3/8” fuel line, and 100-micron pre-filter. Configure the kit at your discretion for use with boosted and nitrous applications, so long as your vehicle operates at or below 650 naturally aspirated horsepower.

Vehicle Fitment:
