360 FBO Ignition no spark

Per this website:
Dave's Place - Chrysler Electronic Ignition System Test
The Distributor Pick-up Sensor resistance should be between 350 to 550 Ohms.
I've seen other sites quotes 150-900 ohms. Confused on which it is?

I tested the pickup coil is showing 293 Ohms. I have an old 340 distributor showing 471 Ohms.

Does the distributor pick up coil appear to be bad?

Thanks!
