Mark, Ive been building models since 1958 and still very much enjoy it!I see you are a Rex White fan well I've got a story, in 67 Rex showed up at the New Asheville Speedway with a 55 Chevy Sportsman car, practiced once,qualified on the pole,won his heat,won the main easily, drove straight to the hauler and loaded car and left. that really bothered me cause I was helping Jackie Fox in the same race but never heard anything. In 2ooo while working for Andy Petree JiM Covey came out there(he was the head of GM racing) and I asked him if he knew anything about what Rex was doing well he said Rex was running the then new 350 engine with electronic fuel injection doing testing for them.
