If you've already removed the timing cover there are markings on the top and bottom gears. Make sure they are lined up before putting the belt back on (if it has a belt) most chevys have timing chains. Anyway, once you've done that and reinstalled everything; the timing is adjusted by loosening the bolt on the bottom of the distributor. Once you've done this, with the truck running slowly rotate the distributor in either direction until the truck is running smoothly in idle. Once this is done retighten the bolt.
