Earlier this month the racers in the 405 area (Interstate 405 for anyone not accustomed to its gridlocks) had the opportunity to blow off some steam and burn the rubber during the 405 Callout event organized by the Thunder Valley Raceway Park in Noble, Oklahoma and Big Marc. And it seems everyone was eagerly anticipating the drag racing relief, especially Ford Mustang drivers. 23 photos
We’ve previously seen what happens during these types of events: drivers draw the chips not to find out the order, but to have the opportunity to call out opponents according to their will, if they’re lucky to have the lowest numbers.

The Thunder Valley Raceway Park in Noble, Oklahoma has been overtaken this past weekend by racers in the 405 area (that’s Interstate 405, the one famous for the gridlocks) that were probably looking to vent some steam at the strip. It was also the place to be for grudge matches, as it apparently is the case with these two Fox Body Ford Mustang racers. 19 photos
Big Marc’s 405 Callout event isn’t exactly just like any other No Prep encounter we’ve previously seen from the
National No Prep Racing Association channel on YouTube because the rules are a bit different. As such, the racers - we see here in the video embedded below the assembly for the 22 contestants in the small tire class - draw numbered chips during the official driver’s meeting.
