Barry Conrad
Back in 1987, Barry picked up a Petty Blue '72 Demon 340 for $1,700. After a year of daily driving, he decided it was time to restore his Demon and paint it Plum Crazy. During the restoration, its numbers-matching 340 was rebuilt and reworked to be a strong street/strip contender. Through the years the Demon has done well at show-and-go events, such as the Musclecar Nationals and NMCA events. Demons were only built for two years and Barry's is a real 340 car (most were Slant Sixes and 318 cars). Future plans call for a 416 stroker and a return to the original Petty Blue hue.
