Holley's Mid-Mount complete accessory system makes use of a compact system for mounting accessories compared to other accessory drives. All accessories mount directly to the water pump, making a virtually bracketless system while giving the whole system a cleaner look. Among the many swap friendly features are bottom heater outlets for clearance in tight applications. The Holley designed alternator is just as innovative. This premium alternator utilizes hairpin/square wire, 6-phase technology as found on the C7 Corvette. The water pump 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.
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, P/S pump with reservoir, and the crank damper. All pulleys and the belt are supplied. Even 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.
