I have a 1/2 mile oval near my home, and a 1/3 mile dirt track. I know a few of the guys that run the "Hobby Stock" class in NASCAR on the paved 1/2 mile, but I'm not too sure about what class it is on the dirt. BTW, the guys running the Mustangs and Pintos in these classes are GREAT sources of used parts, like con rods and pistons, for example. Doesn't really answer your question, but if ya need set-up info or anything like that, I can probally get what ya need, just email me or ask here Ash.
