OK, so you have fuel, spark and compression. You therefore need the spark in the right place. As John suggested test to see if the plug is sparking. Personally I somehow doubt you have 8 faulty plugs, 1 is highly unusual.

Make sure the basic static timing is somewhere near, 0 on the pulley, two loose rockers, rotor arm pointing in the right direction (ish)

Then the leads on anti clockwise 1 3 4 2.

We then KNOW that is correct. If I didn't know how to time up the electronic dizzy, and I'm not familiar with the one you have I'd loosen up the clamp bolt and slowly turn the distributor back and forth with someone turning over the engine on the starter until the car starts. Once its running sort of you can use a timing light. Or i'd temporarily fit a points distributor so knew I was chasing a single fault.

Another old dodge is to get the plugs nice and hot with a blow torch (removed from the engine) before attempting to start it. Leave it sitting with the plugs out for a few hours, wet plugs prevent starting quite effectively.
