65 - 73 Mustang Holley Small Block Ford Mid-Mount Complete Accessory System

HLY-20-370BK

1965 - 1973 Mustang Small Block Ford Mid-Mount Complete Accessory Drive - Black Finish

The Mid-Mount complete accessory system features accessories that are positioned closer together than those in other accessory drives. At its core is a "bracketless" mounting system, where the accessories attach directly to a uniquely designed timing cover, creating a clean and integrated appearance. This design provides excellent engine visibility, allowing you to showcase your engine without unsightly accessory brackets.

The Holley-designed alternator is also a standout feature, utilizing innovative 6-phase technology similar to that found in the C7 Corvette. Additionally, the water pump cartridge shares design efficiencies with the C7 Corvette, enhancing its performance.

The compact and reliable SD7 A/C compressor, along with the Type II power steering pump featuring a baffled reservoir, are seamlessly integrated into the system. The design also offers two heater hose return port locations: one at the upper top and another on the passenger side, low.
