Description

Holley's Mid-Mount complete accessory system has all accessories pulled in tighter than other accessory drives. At the heart of the system is a "bracketless" design, where the accessories bolt directly to the water pump for a clean, integrated form. The design offers superb engine visibility to show off your horsepower, not your accessories. 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 6-phase technology as found on the C7 Corvette. The water pump also shares its design efficiencies with the C7 Corvette. The compact and reliable SD7 A/C compressor and Type II P/S pump with a baffled reservoir.
