I'll second the vote on using factory fans. Mine are off an 88 Firebird, but the same fan was used on the 90's B-Body, Saturn's etc. In general, the factory fan's pull more air than the aftermarket fan's, as many of them are over rated. Look at the amp draw on the fan motor for an accurate comparison.
I also went with the CS130 alternator. again, a factory rated higher amp alternator, that eliminates the aftermarket hype of capacity.
