Just a weird question really not sure if all 93 cars were equipt'd this way or not.

On the crank pulley itself there are two places for a belt, one smaller portion of the pulley closest to the block itself is the belt that runs to the A/C and ETC.

The second pulley is much larger then the first and is ribbed for a belt no idea what its there for tho. any clues?

 

Sounds to me like you have an underdrive crank pulley on the motor. That would be my gues since you say it is smaller and the other one does not have a belt on it.

 

guess its just a underdrive pulley looks like one hell of a underdrive tho

 

yeah under drive, actually makes it easier to go with a generic aftermarket dampener
