Godzilla 7.3L High-Mount Engine Accessory Drive - With Holley Swap Oil Pan and Pump

Complete Godzilla Swap Accessory Drive

The Holley 20-340 is a complete accessory drive package for the Ford 7.3L Godzilla engine. It includes the major components required for a fully equipped front-drive system, including the Holley timing cover and coolant manifold, water pump, 105-amp alternator, SD7 A/C compressor, power steering pump and reservoir, tensioner, serpentine belt and pulleys, plus the Holley high-capacity oil pump and cast-aluminum oil pan.

The result is a consolidated solution for builders who want to install the modern Ford Godzilla V8 into a vehicle (Like a CLASSIC 65-73 Ford Mustang) that was never designed around this engine.

Built for Ford Godzilla Engine Swaps

The high-mount configuration is engineered around the needs of engine-swapped vehicles. Holley designed the system to help position the Godzilla engine correctly relative to the original engine's crankshaft centerline while bringing the accessories up and in for improved packaging. Holley also notes that the system can provide stock Fox Body hood clearance when paired with a low-profile intake.

This makes the 20-340 a strong foundation for custom Ford car (like Classic Mustangs and Cougars) and truck Godzilla swaps, including projects where accessory and oil-pan clearance are major concerns.

Integrated High-Mount Accessory Drive

Instead of adapting individual brackets, pumps and pulleys, the 20-340 brings the primary engine accessories together into one engineered system.

Included components include:

• Holley high-mount timing cover and coolant manifold

• Water pump and water-pump pulley

• 105-amp alternator

• SD7 A/C compressor

• Power steering pump

• Power steering reservoir and hardline

• Power steering pulley

• Automatic belt tensioner

• Serpentine belt

• Accessory pulleys

• Holley Gerotor oil pump

• Holley cast-aluminum oil pan

• Oil pickup and related oiling components

• Oil-pan hardware and dipstick

• Front main seal and installation tool

• Required accessory-drive hardware and adapters

High-Capacity Godzilla Oiling System

One of the key advantages of the 20-340 is its integrated oiling system.

Rather than retaining the Ford Godzilla's original sump-mounted oil pump arrangement, the Holley system relocates the oil pump behind the timing cover. The crankshaft-driven Gerotor pump uses Melling-sourced internal components and is designed around factory-style oil-pressure characteristics.

The included cast-aluminum oil pan provides:

• 6.5-quart oil capacity with filter

• Integrated windage tray

• Oil-control baffle system

• Oil priming provisions

• Oil cooler ports

• 1/2-inch NPT turbo oil drain-back port

• External-access oil-pressure spring port

• New dipstick and oil-pan hardware

The external-access pressure-spring port is particularly useful for builders who want to change oil-pressure characteristics without removing the oil pan. A Holley high-pressure spring kit, part 302-102, is available separately.

Designed for Better Engine-Bay Clearance

Packaging is one of the biggest challenges when installing a 7.3L Godzilla engine into a chassis originally designed for a different powerplant.

The Holley high-mount accessory drive pulls the accessories higher and tighter against the engine than the OE-style arrangement. This can help create additional clearance around the front crossmember and engine compartment while eliminating the factory sump-mounted oil pump arrangement.

For classic Ford Vehicles like Mustangs and Cougards and Ford Truck builds, that packaging advantage can make a major difference when working around steering components, crossmembers, suspension, frame rails and limited engine-bay space.
