I'm not so sure....he is a racer, and racer's typically start off their careers by wrenching on their own junk (no pun intended).
Multi-time NHRA Comp-Eliminator Champion, runs a mid 6 sec. 1/4 mile
IIRC is a Altered (?) Cobalt, turbo'd 4 banger combo, like 1,500 HP
very successfully I may add, wins a tone
he has a special Torque converter operated style conversion, called the Bruno-Drive,
eliminates the clutch, for Lenco's/Jeffco's planetary style drag-race transmissions,
inside the can
knows he way around engines & tuning too
& he's a 2nd (or more) generation gearhead/drag-racer, from the transmission industry
He's not a phony,
yeah he plays it up for the camera on TV,
he's a pretty boy, blonde haired blue eyed well built
(he's like 50+ now)
but knows his ****, cars/4wds, & he's been doing it for decades,
Races & TV, now a commentator for NHRA Mission Foods series, & now the Pro-Mod series
(which he drove), Pro-Stock (which he also drove) along with other Comp classes...
