Yep Lappy, the Busch cars used to run the 6 cylinders, but not the trucks. Those sixers were loud, and with a whine that was so much higher than the throaty V8's.
As to the restrictor plates, all I can say is that so many people say that they hate this type of racing, but these races, Dega and Tona, produce some of the closest racing they've ever had and if anyone can sit tight while these races are ongoing, they don't have any sense of danger, thrill or whatever. Yep, I've heard many more people tell me they hate this type of racing, but there are plenty of people who love it and will fill the stands more and more. The ones who hate it the most are the drivers and who could blame them? Fortythree cars all in a pack is certainly exciting to watch, but hell to be in going close to 200 mph. For any of you who don't like those races, I'd suggest you forego them for any local racing and just read about it in the papers. The local racing will easily be more exciting anyway, even for those of us who like the closeness of plate racing.
