What the hell does constitute a "massive rule change" in your book, if changing both the configuration of the engine and how it breathes does not?
I started to think back in history and there have been 2 times in F1 history when domination has been stopped by massive rule changes - 1961 with rules changing to 1.5 engines and 2014 with the new hybrids.
Banning the active suspension comes close but Williams had still very much a dominant car until 1998.

Other times (like banning sideskirts in 1981 or ground effect completely in 1983 or even 2009 did not have one team dominating at all previous to the changes)

Maybe new engine rules in 1952 that made Alfa quit stopped a domination
