I talked to auto specialties and they make a pulley for the standard 4.7. I gave him my vin# and he ordered a factory pulley to see if it would work. He said it would fit and the aps pully was just lighter. Has anyone bought one for a 4.7 H.O?

If it's the same diameter, but just lighter then it won't do anything for you.
Lighter pulleys can make some difference on small displacement 1.6 ~ 2.0 liter rice burners since they need all the help they can get at low rpm to accellerate quicker. On larger displacements, bottom end torque isn't an issue.
