Need help, Dart won't start...

1971 Dart Swinger I just finished putting in my 318 (original /6 car). I checked the coil and it's good, ballast resistor is good, battery is good. I have new spark plugs and wires. It will turn over but won't fire, doesn't even try. Gas is pumping and I tried priming the carb, no fire.

Some background: The car then I got it wasn't running took out the 225 and put in a 1971 318, still has points ignition. I put new points and gapped it to correct gap and new condenser. My guess is something isn't right in electrical. Any help would be greatly appreciated.
