Holley is proud to present our revolutionary high-mount accessory drive and oiling system for the Ford 7.3-liter Godzilla Engine. With our patent-pending technology, we have integrated the timing cover, oil pump, oil pan, water pump, alternator, and the option for A/C and/or P/S, all in one streamlined system. Furthermore, this versatile accessory drive is compatible with both factory crank pulleys and aftermarket damper/pulleys.
Positioning an engine swap correctly is crucial, ensuring it aligns with the vehicle's original engine's crankshaft centerline. Our innovative solution achieves just that, allowing proper engine placement while providing clearance for a stock Fox Body hood (when used with a low-profile intake). Our system replaces Ford's sump-mounted oil pump with a high-capacity gerotor pump positioned behind the timing cover, gaining crucial crossmember and ground clearance. To ensure reliability, we have incorporated a proven pump design utilizing Melling sourced components (M462 with powdered metal gears) that mimics the factory pressure level. Should your application require additional oil pressure, we offer a high-pressure spring kit (part# 302-102) for easy installation. Unlike most pumps that require removing the oil pan to change the pressure spring, we have introduced a first-of-its-kind external access port, allowing hassle-free spring switching. Moreover, our cast aluminum oil pan features a performance-minded windage tray and baffle, guaranteeing proper oil pickup during high G maneuvers. For extreme situations, such as drag racing, upgrade to the optional race baffle (part #302-105) to always ensure proper oil delivery. For those interested in adding an oil cooler, see Earl's part #GZ0001ERL which offers dual -8AN male fittings for this purpose.
This Holley accessory drive system offers flexible configuration options to meet various needs. For instance, we provide different alternator choices to cater to diverse performance and electrical requirements. If you prefer a customized modular setup, you can opt to exclude the A/C and/or P/S components. Our "base kits" include everything except these optional components. Alternatively, you can choose our "Holley Complete Kit" for the most commonly selected, cost-effective combination. Holley's Godzilla High-Mount Accessory Drive is the ultimate solution for engine swaps, offering unparalleled functionality, adaptability, and ease of installation.
