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.

Holley Sniper 2 EFI Returnless Fuel Injection Systems are self-tuning, easy-to-install, EFI conversions for 4-barrel (4150 flange) style carburetors. They took everything that they learned from the original Sniper EFI system and added new features that will make your EFI conversion more simple, reliable, and modern. Like all Sniper EFI systems, Sniper 2 is designed to work with the Sniper Ecosystem that includes Hyperspark ignition, complete fuel systems, multiple user interfaces/dash displays, and more. New for Sniper 2 is the Power Distribution Module (PDM). This cost-effective and optional accessory isolates the core of your EFI and ignition wiring into one, easy-to-use location. Simply slide the stripped wire ends under the positive lock connector and tighten down the set screw. Battery and a switched 12 V source is all that's required to power the PDM and your Sniper EFI. Make your classic drive like a modern fuel-injected vehicle, with easy cold starts, smooth drivability, and improved fuel economy! Sniper 2 is designed to be installed at home in your garage with limited tools and the support of Holley's comprehensive installation manual and videos.
