LOL. I was once went to get a wheels stud for my 300zx and the worker was outside smoking a sig. The whole thing went alittle something like this: I roll up, get out of the car, he ask's me why its still running, I say its on a timer. He then tells me my z which is running rich is running lean. I ask him why he says that? he says U dont hear the motor rev up and down? I tell him its a fully built motor and those are cams and solid lifters doing that. He then feels dumb and says he wants to race me in a neon with a srt4 motor without the turbo its fast enough!!!!
