Bristol, Tenn. (WJHL) — Due to impending weather on Friday, the schedule has been moved up for the Thunder Valley Nationals at the Bristol Dragway. The pro stock qualifying gets underway at 5 p.m., and the Nitro starts at 6 p.m. Gates open at 10:30 p.m.

When they light the fires, you will get a chance to see the top fuel dragster go 60 feet at 100 miles per hour, and there is no one better at it than Steve Torrence — a four-time defending national champion.

However, Bristol has not been too kind to Torrence who won in 2013 but finished runner-up four times — including in the past two seasons to Mike Salinas. Torrence says there are so many things that factor into winning Bristol.
