Riddle me this, Mopar electrical experts.......

It's too much of a coincidence that the problem would appear right after the engine swap and not be something related. Since there has been other changes made since that time, you may have multiple problems now. It's going to take someone with a test light or meter and some electrical knowledge to trace it down. No power to the coil should be fairly forthright. Any decent auto electric shop should be able to find the problem in no time.
