No spark HELP!

Got everything done on my 65 Dart 440 conversion, went to start it for the first time and no spark. I am running the Mopar Performance orange box same exact setup I had on the 318 and it ran the day I pulled the motor. I tried 2 distributors, 2 coils and no spark. Obviously I have some wiring wrong somewhere. I have the blue wire going to the Ballist resistor, the black wire to the negative side of the coil and the harness running to the distributor. Can someone give me some advice on what to check, I have run through wires there is power at ballist resitor, power to the coil power at the ecu, but no spark. Any help is appreciated.
