For those that don't know or think it is just coincidence that these teams grouped in the 60's and 170's before some year (1997?) teams were reassigned numbers every year. The first year of permanent numbers the numbers were assigned in alphabetical order by sponsor. THe success of the teams in the 60's is centered around the GM sponsored teams, the Teams in the 170's are (or were) mostly UTC sponsored. I am sure the teams mentioned would agree that having the support of these sponsors is a large reason for their continued success.
