Could be that your distributor is turned too far away from tdc. Short and simple way is to turn the motor by hand to to get #1 at tdc (the timing marks on the front cover and harmonic balancer should be lined up) then adjust the ditributor so that the rotor points to the little '8' on the distributor body. That will get it very close to where it should be.
To set the camshaft retard offset(+/-2 degrees) properly, you'll need use of a scantool that can monitor that in real time.
This pic shows the rotor pointing to the '6'. The '8' is the other trianglular point on the bottom of the flat side on the left.
