Crafton has 301 Camping World Truck Series starts to his name, but hasn't competed in a Nationwide or Sprint Cup Series race in his career. He leads Jeb Burton in the series points standings by 23 points.
Rounding out the top five were Sam Hornish Jr. (31.422 seconds, 171.854 mph) -- who led the way until Crafton's late lap --, Cole Whitt (31.427, 171.827), Brad Keselowski (31.442, 171.745) and series points leader Regan Smith (31.473, 171.576).
Kyle Busch, who is driving in all three races (along with Keselowski), had the sixth-fastest time.
Justin Allgaier, who took a huge hunk of Smith's points lead and is second in the standings, was 20th. He didn't do a mock qualifying run.
The Feed the Children 300 is scheduled for 7:30 p.m. Friday and will be televised on ESPN.
