Holley’s Mid-Mount accessory drives are now available for your SBC and BBC engines! The revolutionary system does what no other accessory bracket system has done… GETS RID OF THE BRACKETS!


This is Holley’s first accessory system for SBC and BBC, and they start at the top. The Mid-Mount complete accessory system has all accessories pulled in tighter than other accessory drives. At the heart of the system is a patent pending “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. The Holley designed alternator is just as innovative. This premium alternator utilizes square wave, 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. 


  • Bracketless accessory mounting with ultra-easy assembly.
  • Hidden thermostat bypass and heater hose ports with NPT line adapters included.
  • Compact SD7 A/C compressor with line adapter included.
  • Type II power steering pump with baffled reservoir.
  • P/S adapter hardline to AN -6 adapter included.
  • OE pulley ratios for optimal accessory performance.
  • Available in natural and black finishes.
  • Billet alternator, and compressor pulley covers.
  • LT1 style water pump design.
