Holley Godzilla High-Mount Accessory Drive - With Holley Swap Oil Pan and Pump - Complete Kit

One system instead of nine decisions. A Godzilla swap gets hard at the front of the engine. The factory oil pump lives in the sump; which is exactly where your crossmember wants to be; and the factory accessory layout puts the alternator and the pulleys out where the frame rail already is. Most people solve that with six brackets from five vendors and hope the belt lines up. Holley integrated the whole face of the engine instead. Timing cover; coolant manifold; water pump; alternator; A/C; power steering; oil pump and oil pan in one patent-pending system - and it pulls every accessory up and in tighter than the alternatives; so the crank centerline can sit where the original engine's centerline sat. The oiling side is the real engineering. A crank concentric gerotor pump with Melling internals moves behind the timing cover; the pan clears the crossmember; and the pressure spring changes through an external access port instead of by dropping the pan. The cast aluminum pan carries 6.5 quarts with filter plus a windage tray and baffle that keep the pickup covered through a corner. Small details that show up later: heater hose connections relocated out of sight; a new front main seal with the install tool in the box; and alternator options that run without the original ECU telling them to. This is the Complete Kit - the common combination with A/C and power steering included; all adapters; accessories and the belt. Natural as-cast aluminum or black.

  • Crossmember clearance - the gerotor oil pump moves behind the timing cover and off the sump floor.
  • Correct crank centerline - accessories pulled up and in so the engine sits where the original one did.
  • 6.5 quarts with a baffle - cast aluminum pan with a windage tray that keeps the pickup covered under load.
  • Spring changes without dropping the pan - an external access port for the oil pressure spring.
  • One box; one belt - timing cover; water pump; alternator; A/C; power steering; pulleys and belt all matched.
  • Tidy front end - heater hose connections relocated out of sight over the OE design.

Install Level: Advanced - engine swap component; front cover and oil system assembly

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 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. Our 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.
