I have a petronics unit in my factory 6cyl dist in my 59 apache, been there for 12 yrs. without any problems. A friend has one on a 327 factory dist. same time frame never a problem.
Now the haters will be along any second telling you to run away as fast as you can from it. Also throw it as far as you can, it will never work. will leave you stranded.
From my experience with it, The distributor was converted by a ignition shop, and obviously assembled properly. There has been no problems at all with it.
Would I do it again yes I would. But I would also explore the other options available that I was not aware of when I purchased it 12 yrs. ago.
