Lost spark suspect coil

Hello
I lost spark coming out of coil tower wire to ground. Been temperamental driving car shutting off randomly but finally died at my house permanently it seems.
I have the mopar performance coil p 4876732 now with orange box. I’m measuring .7 ohms primary but my secondary is coming in at 5000 ohms I was expecting higher 10-11000 ohms. I realize it could be other issues but I figured I’d start with a coil easy enough based on my readings. It does not look like they make this coil anymore. I do have plans down the road to go to an MSD ignition with future engine. Is there an MSD coil I can put in now to use I have an electronic dizzy on a 383 motor.

Thanks
