As registrar you are correct.
I listed both differently in 2023 Registry unfortunately there are more than one of these stories.
Most AK questions so far are 427 cars or specials as no 5.0 cars are in question.
Most likely as they (5.0) were DOT and Federally monitored with Ford.
Guessing as the big block (special) either were sold as rollers or as classified parts that’s where the confusion came in these years later.
Lot more hand waiving.

So far these are all no doubt AK cars just a bit confusing. Unlike actual cobras which have extreme seven-figure value these so far are moderately priced and seem to be just miss numbered.
I don’t think this is something that was meant to be intentional.

BTW the two blue cars listed above are the same car.
I’ll post a pic of Registry later.
