"Back in the day" weren't they called like B cars and maybe the "Indy-type" cars were A-cars or smthn? I know they (the Indy type cars) were called Big Cars. Possibly until there was a split of the Indy 500 type cars to the "half-mile" cars? I swear I read this in maybe the Bettenhausen book (it was like a history of racing); but I don't have the book anymore.
