Overview

Holley's high-mount accessory drive and oiling system for the Ford 7.3L Godzilla Engine integrates the timing cover, oil pump, oil pan, water pump, alternator, and options for A/C and/or P/S. It's compatible with factory and aftermarket crank pulleys. This system allows proper engine placement and provides clearance for a stock Fox Body hood (with a low-profile intake). It replaces Ford's sump-mounted oil pump with a high-capacity gerotor pump (Melling components) behind the timing cover for increased crossmember and ground clearance, mimicking factory pressure levels. An external access port allows easy high-pressure spring kit installation (part# 302-102). The cast aluminum oil pan features a windage tray and baffle for proper oil pickup during high G maneuvers, with an optional race baffle (part #302-105) for extreme situations. Earl's part #GZ0001ERL offers dual -8AN male fittings for an oil cooler. Flexible configuration options allow for different alternators and optional A/C and/or P/S delete. "Base kits" exclude these optional components; "Holley Complete Kit" is a common, cost-effective combination.
