I bought a 1997 suburban with a 7.4 and a side mount whipple supercharger.the suburban is totaled and I plan to install the whipple on a 1997 k3500 dually.my question is about the fan pulley.the pulley is aluminum and has a groove cut in it about the width of the serpentine belt.I’m not sure that this groove is supposed to be there.does anyone have the same kit and could post a picture of their pulley.thanks in advance
