Holley 20-370 Small Block Ford Mid Mount Complete Accessory System Small Block Ford Mid Mount Complete Accessory Drive Natural

Holley's Mid-Mount accessory drives are available for small block Ford engines! The Mid-Mount complete accessory system has all accessories pulled in tighter than other accessory drives.

At the heart of the system is a bracketless mounting, 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 Holley designed alternator is also innovative. This premium alternator utilizes 6-phase technology as found on the C7 Corvette.

The water pump cartridge also shares its design efficiencies with that of the C7 Corvette. The compact and reliable SD7 A/C compressor and Type Ii P/S pump with baffled reservoir are also integrated.

The design provides two heater hose return port locations (upper top & passenger-side low). When we say complete, we mean complete.

The Mid-mount system comes with everything you need. All accessories are included; the water pump, A/C compressor, Alternator, and P/S pump with reservoir.

All pulleys and the belt are supplied. Heater hose adapters, power steering to -6 An hardline, and the alternator plug/harness are included.

Easy assembly was a priority during the entire development of this accessory solution. Color graphical instructions walk you through every step of the installation.
