All the cars are racing in a bracket format against the car that is most closely paired regarding performance. So one year there was a really tired 1970 GT500 Shelby running against a 1972 Buick Electra 225 because both cars were running high 15 second times. Meanwhile I was running my 428CJ '68 Cougar 3.50TL C6 against a 1968 Firebird 3.55 400 4 speed because both of us were running 13.75.
