Accessory Drive Systems, Mid-Mount, Serpentine, 150 Amp Alternator, GM Type 2 Power Steering, SD-7, Natural Finish, Ford, Kit
Holley's mid-mount accessory drives are available for small-block Ford engines. These systems have all accessories pulled in tighter than other accessory drives. At their heart is a "bracket-less" mounting design—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 premium alternator utilizes 6-phase technology as found on the C7 Corvette and only requires a one-wire hookup. The water pump cartridge also shares its design efficiencies with that of the C7 Corvette. A compact and reliable SD7 A/C compressor and Type II power steering pump with baffled reservoir are also integrated. This system design provides two heater hose return port locations (upper top and passenger-side low).
The mid-mount system comes complete with everything you need: the water pump, A/C compressor, alternator, and power steering pump with reservoir. All pulleys and the belt are supplied, along with heater hose adapters, power steering to-6 AN hardline, and the alternator plug/harness. Color graphical instructions walk you through every step for an easy installation. Systems are available with a natural or black finish.
Features and benefits:
• Bracket-less accessory mounting integrated with supplied front timing cover assembly means this kit will work on all block deck heights
• Water pump inlet pipe mounts for either driver or passenger side lower radiator hose routing; timing cover also has mounting for driver or passenger side ignition timing pointers to accommodate all needs
• Two return heater hose ports (upper center and pass-side low) with hose adapter/port plug included for a complete solution
• Crankshaft belt pulley configured for 3 or 4-bolt crank dampers; spacer P/Ns 97-446, 97-447, or 97-448 are available for purchase to adjust for different OE crank damper pulley flange depths
• Power steering may be deleted with a drivebelt change; see installation instructions for the commonly available drive belt required
• A mechanical fuel pump may be used with this kit. See installation instructions for required timing cover mod to be performed; and the power steering pump will need relocation (use kit 97-436); a remote mounted P/S reservoir is also required
