I just recently replaced my entire motor and the timing marks by the book were both at the top on the crank and cam, but the rotor was pointing to the the #4 plug in the distributer cap (look inside the cap and you will see these numbers)this turned out to be the #1 at top dead center with these timing marks, and the truck ran perfect, it was also in the same place when we removed the dist from the old motor.
