Heads/cam is where you draw that line.

Blower swap isn't a standard bolt-on and not even close far as comparing swapping a IM. Does it bolt to the exterior of the engine yes, but swapping one out to a larger unit is effectively increasing the displacement of the engine. So it needs to be mentioned in the list or categorized differently then those cars still working with the stock LT4 1.7.
