It doesn't look like a stock 03 Mach 1 automatic would have a chance? Everything has 100-200 more hp in the street tire class. I'll give a GTO a go but an 07 Zo6 is way out of my league, both $$ and e.t.
How do you propose to run a 500 hp Vette vs a 300 hp 01 Cobra or Mach? I'm having trouble invisioning how the matchups are going to happen.
