All based on the fore mentioned NOVA, GM also did this in the 80's with the celbearty,olds' ciera,buick centruy and pontiac 6000. Not to mention that it was also used in their full sized wagons as well, Caprice/Impala,Pontiac Catalina Grand safari,Oldsmobile and buick . And in the 90's full sized wagons from Chevy,Olds and buick. any of which could have any engine under the hood be it a chevy ect. Buick mostly used their own engines where as olds & pontiac would use chevy engines as well as their own.
