you just posted stuff for a demolition derby. While some of that stuff is pertinent to short track racing, a lot of it isn't and likely isn't allowed.

Back to your original question - Read the complete rules for the class you're going to run at the track you're going to run it - From my experience nearly all Street Stock/Pony Stock/Super Hornet classes I've seen require that the engine be totally stock.
