If I remember right from doing my 88, there should be dots that all line up on the gears and off colored links on the timing chain. Stick a screwdriver down #1 spark plug hole you can feel the piston hit TDC and then start moving down. Look at the timing marks and make sure you are not out 180 degrees.
