The included fuel system places a 340 LPH fuel pump in the tank, which can easily be accomplished with basic hand tools.

This includes four 100 lb/hr injectors, built in timing control (when used with a HyperSpark or Pro Billet distributor), a 3.5" full color touchscreen, and much more! The throttle body will support up to 500 naturally aspirated horsepower. In addition to all of these tried and true features, the Sniper EFI Quadrajet system will fit most stock air cleaners and offers multiple fuel inlet configurations that allow for a stock appearing installation.
