      Serpentine Moves forward on A/C compressor pulley

      The Serpentine belt moves forward two grooves (up and over the A/C compressor pulley). We've ground the bracket to move the compressor pulley forward twice & replacing the belt too, but is still moves the same amount. It's a 67 Camaro with an LS3 out of a 2011 SS Camaro, Holley Accessory Drive System Part# 20-138. I'm open to suggestions, thank you!!

      something's out of alignment. either the A/C compressor is too far back or it's crooked relative to the other pulleys would be my guess.

      There’s alignment front to rear but also all pulley center lines need to be parallel.

      Greenlight,
      I had the same issue about drove me crazy!
      Put a combination adjustable level vertical on
      the crank pulley, rotate the dial until it is level.
      Lock it down. Now put it on the A/C pulley
      adjust the A/C pulley to be level also. This will
      align the A/C pulley at the same degree as the
      crank pulley. Hope this helps
      Billy
