After the teams 1-2 finish in the 2003 Bathurst 24 Hour, Garry Rogers said in an interview with Australian Muscle Car (AMC) Magazine that with the restrictions that PROCAR forced the team to have on the 7.0 litre V8s, such as induction and rev limits, he believed the cars would actually have been faster using the smaller Gen III production based engine which would have been almost restriction free, as seen with the Mosler MT900R which used the 5.7 litre motor. He also refuted that having a professional team such as GRM made the car unbeatable at Bathurst, stating that had anyone built a V10 Viper to at least the same standards and had professional drivers like the Monaros instead of part-timers and gentlemen drivers, then ""nobody would have seen which way they went"", as during the Nations Cup Championship, Greg Crick's privately entered Viper had shown on a small budget that it was capable of beating the Monaros.
