Holley Ford 7.3L Godzilla Alternator Kits
The factory alternator on the 2020 and up Ford 7.3 L Godzilla engine is a bulky single or dual alternator design that is tough to package in an engine swap. The Holley Ford 7.3L Godzilla alternator kits provide a more compact solution for extra clearance and works with the factory timing cover, water pump, damper/crank pulley, and intake manifold. They also will work with after-market damper/crank pulley. The bracket and alternator are compact and lightweight, and the Holley alternator is easy to wire and does not require the factory ECU to function like the OE alternator. Holley includes the plug/pigtail, pulleys, and belt in a complete kit. Please note the included belt is for alternator-only applications, but the instructions specify the belt for other configurations. The bracket allows for any accessory configuration, and it works with or without the air conditioning compressor and with or without a power steering pump. Features and details: * Alternator kit and mounting bracket for Ford Godzilla 7.3-liter engine swaps * Great solution with everything needed to add an alternator to the Ford 7.3-liter crate engine * Eliminates bulky dual alternator system—factory setup on some heavy-duty trucks * Works with the factory timing cover, water pump, damper/crank pulley, and intake manifold—also works with after-market damper/crank pulley * Compact design with alternator pulled in tight to the engine for extra clearance under the hood * The mounting bracket is compatible with Holley alternator models: PN: 197-300, 197-301, 197-302, and 197-303 * Easy wiring of alternator and does not require factory ECU to excite alternator—wiring pigtail included * Choose from a complete kit with 105-amp Holley alternator (PN: 20-380), or bracket kit (PN: 97-409) * Natural as cast finish on the mounting bracket and alternator * Works with or without an air conditioning compressor * Works with or without a power steering pump * For alternator-only race setup, Holley bracket PN: 97-409 should be used with Holley premium alternator (PN: 197-302 or 197-303)—ideal for high rpm applications (alternator designed and tested for up to 30 percent higher rpm) * Ideal for use on Godzilla crate engines and engine swaps
