Slant 6 No Spark

I should point out too that the motor turns over and is getting fuel. Also the ballast resistor is new so it's not that either. I did convert the car over to electronic ignition from points when i swapped engines. (old slant 6 was blown, so I put a super slant 6 in). I checked the wiring several times over when i did it, so I know it's correct (I was very paranoid about getting it wrong). And it ran fine for about 6-8 months after the conversion.
