Jimmy Prock cam 🎥 Ever wonder what a crew chief does before a run? Jimmy and Chris are on the radio checking track conditions and relay final adjustments to the guys in the lanes. Jimmy will make adjustments in the box if needed. He lines me up, guides me up to the beams, sets the idle, and richens the barrel valve. After that, it’s go time! #NHRA #RobertHight #JohnForceRacing #Nitro #FunnyCar
