Aluminum pulley to reduce the mass.

EDIT: I've been running a GM pulley with a GM belt for a number of years and had become used to the belt noise from two different width belts running on the crank and water pump pulleys. When I started the 40 up, the first thing I noticed was just how quiet the engine was with two factory width belts. Needless to say, the effort was well worth it as I'm very happy with this conversion.
