If check engine light is flashing it is flashing because you have a engine miss fire.

You need to pull codes and post back code no.

Was camshaft retard set after dist replaced?

Did you use AC Delco cap and rotor and plugs in it?

Several things can cause miss fires.
Bad secandary ign system.
Camshaft retard setting.
Low fuel pressure.
Bad VCM sensors.
Compression bad on cylinders.
Bad fuel.
Low fuel pressure.
Vacumn leaks.

Post back your code no.
