MID-MT ACC DRIVE SYSTEM,SBF-BLACK

Brand New Holley Small Block Ford Mid-Mount Complete Accessory System, Black Finish (Part #20-370BK).

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 "bracket-less" 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.
