Quite a few B-O-P new car buyers tried to sue GM for fraud when they found out their new Buick, Olds or Pontiac had a Chevy engine under the hood.
makes sense to me.
yes i have seen quite a number of different motors under the hoods of olds, pontiacs, monte carlos, malibus of the 70's -80's... even seen an olds motor in a 80'schevy p/u once in the junkyard. thought that was weird.
