The no-prep series really woke up some of those guys as to what real racing is all about, with all the travel to different places and the effort and parts required to not only run a series but to go rounds. Birdman, Fireball and Larson were clearly superior to the others, as they had a crew and spare parts to keep things moving. When they did their first round callouts there were always 2 or 3 that were broken from the day before, whereas the 3 I mentioned were able to change engines or transmissions to stay in competition.
