Wife raced a '68 Camaro with a Pontiac 455 (468) bracket car. Very consistent.
Mine was a '68 Javelin 401 (406) AMC SS/B
Yes...as Moss said, racing you quickly realize is the "battle of the fat wallet" I thought. Bracket gives everyone a chance.
That can be bad also. I remember an older lady in a Mercury station wagon who would actually stop at the high end...inches from tripping the light and wait. Some fast car would come flying up and at the last second nail it! She won lots of times. So if her car ran, say, a 17.5 she would dial in a 15...knowing she'd never break out. An 8 second car would have to spot her...wait until she was close to finish where she waited!
