im getting ready to do a cam swap and lot of internals so the motor will be out of the car. while it was out of the car i was thinking of doing pulleys and was first wondering what is the difference of underdrive and overdrive pulleys? and also what would be the best pulley? and what would be the best pulley combination? and is the adjustable belt tensioner worth the money?

ASP UD pulley

UD = reduce accessory power
OD = increase accessory power

if you get an UD crank pulley it will slow down your accesories, alt, Power stering, A/C, water pump, ect.... some people complain that it slowed down the charging system enough that the alt cant keep up enough to charge the battrie you can install a over drive alt pulley to correct that.

I just ordered an ASP UD pulley friday.
