For future Reference a 94" serpentine belt works great with cat power UD pulleys. At a little over $40 their a pretty good deal. I don't think their powder coated like the march set, but for half the price I can live with paint.

I'm just running the crank pulley and my alternator isn't having any trouble keeping up with the 25% under drive. I wouldn't recommend running the alternator pulley as its going to be running at 42.5% under driven with a 23% underdrive pulley.
