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.

Q & A
In this episode, Project Chevelle takes a big step in its muscle car transformation. It's out with the little old 307 and to the dyno with our new 383 from BluePrint Engines!
In preparation to transplant a 430hp 383 stroker into Project Chevelle, Zach R. made up a set of plug wires for the car. To keep it nice and tidy they needed to be routed just right, be the perfect length and not distract from the engine!
Kevin W. walks through each step of installing a new alternator bracket on a 454 Big Block Chevy.
