fans used with Fan spacers. Still if cooling is the primary concern, the factory
AC pulley setup with the 7 blade Clutch Fan is the high water mark. Since the AC
pulley itself is separate and removable, the appearance is not a problem, but a
Spacer (same as the strengthening spacer on the crank pulley) can be used in place
of that inner AC pulley. Use this set-up on my Car, and it works very well, but
anyone with Pontiac knowledge would know it's not original at a glance. Pulleys
are aftermarket now, including some nice ones from CVF Racing, and the 7 Blade Fan
is a very common item. Get the Heavy Duty Clutch, Standard Duty's are questionable.
