    Which system are you referring to. I have a buddy that put the serpentine on his. Is it the serpentine or v-belt? It's pricey either way. I would spend my money on something else.
    It looks nice but who looks under the hood all the time? I like it clean with some fancy trim and whatnot, but the $950 he paid for his plus new A/C compressor b/c the old wont work, and new alt and pwr streering pump, IMHO was not worth it. It works great after all the new accs. The alternator does not charge well still (it's a 140 amp) b/c the pulley slow down the accs.

    If its for show, I say go for it, if not keep it stock and simple. If you still want serpentine, go to a junkyard and find one from an 89'-94 tbi 4.3, 305, or 350.
