NHRA *has* crate motor cars... they're called Cobra Jets and Challengers...
Not to mention all the superceded parts, fuel cells, wheelie bars, CSR/Meziere water pumps. -=shrug=- It is what it is.
Just pickin!
Like I said, doesn't matter. I've always said, "Tell me what the rules of the playground are, and I'll go play on it."
Hope the weather holds off today.
