This design offers superb engine visibility to show off your horsepower, not your accessories. 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 that of the C7 Corvette. Also integrated are the compact and reliable SD7 A/C compressor and Type II P/S pump with baffled reservoir.

The water pump design incorporates optional side or top heater ports. The top thermostat bypass and heater ports are recessed into the manifold. So, if you don't need them, you don't see them.

When Holley says “complete,” they mean it. 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. Even A/C line adapter, 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 ultra-easy installation.
