Holley Terminator X Stealth 4150 EFI systems feature 4 or 8, 100 lb. fuel injectors capable of supporting up to 650 hp naturally aspirated, and 600 or 1250 hp on forced induction applications. The Terminator X ECU is capable of fuel map self-learning and ignition timing control, improving idle stability, drivability, and wide-open throttle horsepower! The throttle body has the standard 4150 carburetor flange so it will bolt down where your square bore carburetor was. Holley Terminator X Stealth 4150 systems also include transmission kick-down provisions for GM TH350, TH400, 200R4, 700R4, and Ford’s C4 and C6 applications!
