Is there a west coast rule book for IHRA?

Not trying to argue, Just trying to understand what is legal in IHRA. My car in NHRA can run AA/SA, A/SA or B/SA, It has the Nascar Hemi with thin gauge steel and hood scoop. It is currently rated at 440hp with a minumum weight of 3690 in A/SA. It is the long wheelbase with a P/W factor of 8.09.

Where does it fit in IHRA? I heard IHRA uses the original factory HP ratings, So does that mean I'm at 400hp? Fiberglass instead of thin steel? Fiberglass hood scoop?

Why are there only a few racers that have set records in IHRA? Almost all classes are at a minumum..

Can I really run the 71 demon hood scoop on my 71 duster?

Thanks for the help guy's
