Yep - Happened several times last year at Wall. One Factory Stock camaro Factory Stock's engine failed tech. A few other cars in Different Classes were DQ because of other reasons. One Sportsman had a illegal carb. Funny thing was it was posted the next day on this forum with no explanation, why half were DQ !
At Bridgeport - In the Outlaw Stock Class, the Winner of the first race in 2017 was DQ. If memory serves correct.
