with the smog test, there is a visual inspection so they'll want to see the stock components under the hood. it's *highly* unlikely that a testing station would even know what a 1982 dodge distributor, ECU and coil even look like, and as such would reference the official data they have access to, which naturally, would be pictures of stock stuff.
so then, them seeing something that is not stock, give you an automatic fail.
the exception to this rule, would be a emissions legal MSD HEI type distributor which has an executive order that specifically allows for them, but also has a near $600 price tag.
all of this is to say that the OEM chrysler EI is fine for this application.
