It is interesting, Milwaukee, Springfield programs called the Champ Cars or BIG CARS. Some assumed Big Cars to be Sprints but actually not as I saw a program from a "champ race" at Williams Grove that said BIG CARS.
Open Wheel racing has always had a hard time IDing itself. Midgets in the 1960's became Offy 110s and Compact Sprints. Sprints were Sprints and Spring and Big Cars.
So it was always a problem. So lets use the Lindsey Hopkins effort of 1965. He had a Lola/Ford that Bud Tingelstad raced at Indy, a laydown Kuzma Roadster Bud raced at Milwaukee and Kuzma Dirt Car Bud raced on the pavement at Langhorne in three races in a row. So which is the Indy Car? In my book the car that raced at Indy, the Lola/Ford. The Roadster now could fall into the Champ Car category as it did not race at Indy and the Dirt Car is a Big Car like the 1965 Program at Springfield called them.
