Holley's mid-mount accessory drives are available for small-block Ford engines. These systems have all accessories pulled in tighter than other accessory drives. At their heart is a "bracket-less" mounting design—the accessories mount directly to a uniquely designed timing cover for a clean, integrated form. This product offers superb engine visibility to show off your engine, not unsightly accessory brackets. The premium alternator utilizes 6-phase technology as found on the C7 Corvette and only requires a one-wire hookup. The water pump cartridge also shares its design efficiencies with that of the C7 Corvette. A compact and reliable SD7 A/C compressor and Type II power steering pump with baffled reservoir are also integrated. This system design provides two heater hose return port locations (upper top and passenger-side low). The mid-mount system comes complete with everything you need: the water pump, A/C compressor, alternator, and power steering pump with reservoir. All pulleys and the belt are supplied, along with heater hose adapters, power steering to-6 AN hardline, and the alternator plug/harness. Color graphical instructions walk you through every step for an easy installation. Systems are available with a natural or black finish. Features and benefits: * Bracket-less accessory mounting integrated with supplied front timing cover assembly means this kit will work on all block deck heights * Water pump inlet pipe mounts for either driver or passenger side lower radiator hose routing; timing cover also has mounting for driver or passenger side ignition timing pointers to accommodate all needs * Two return heater hose ports (upper center and pass-side low) with hose adapter/port plug included for a complete solution * Crankshaft belt pulley configured for 3 or 4-bolt crank dampers; spacer P/Ns 97-446, 97-447, or 97-448 are available for purchase to adjust for different OE crank damper pulley flange depths * Power steering may be deleted with a drivebelt change; see installation instructions for the commonly available drive belt required * A mechanical fuel pump may be used with this kit. See installation instructions for required timing cover mod to be performed; and the power steering pump will need relocation (use kit 97-436); a remote mounted P/S reservoir is also required * C7 LT1 style premium alternator, 150 amp * C7 LT1 style water pump design * Compact SD7 A/C compressor * Type II power steering pump with baffled reservoir * P/S adapter hardline to-6 AN adapter included * OE pulley ratios for optimal accessory performance

Holley's Ford 7.3L Godzilla high-mount accessory drive complete kits with their patent-pending technology, integrates timing cover, oil pump, oil pan, water pump, alternator, and the option for A/C and/or P/S, all in one streamlined system. Plus, they are 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. Holley's 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, they incorporated a proven pump design utilizing Melling sourced components that mimics the factory pressure level. Unlike most pumps that require removing the oil pan to change the pressure spring, Holley introduced a first-of-its-kind external access port, allowing hassle-free spring switching. Moreover, their 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 to always ensure proper oil delivery. These accessory drive systems offer flexible configuration options to meet various needs, making Holley's Godzilla high-mount accessory drive kits the ultimate solutions for engine swaps, offering unparalleled functionality, adaptability, and ease of installation. Choose from natural as-cast aluminum or black finish.
