leaf springs viable?

Daayyyyyammmmmmmmm! That's a bada$$ dart! cracked me up when he says "all mopar" lol there has to be some Non mopar stuff in that car to run that fast! My dragster with the 500 indy motor runs that exact time and his is a door slammer!!! Wonder what car from B & B race cars went faster? Anyways that was an adrenalin rush! Makes me anxious to get back home to florida and take the rail out to the track!
