O/T Pro stadium truck racing?

Does anybody know if theres a site for pro stadium trucks and how to find out where to race?
I`m building a ranger with a 5.0 efi engine and i got 2 sponsors already. I`m totally new to racing.

 

Go to http://www.race-dezert.com/

 

You might want to read some rules BEFORE you start building... just a thought...

 

I`m trying to download the ushra rule book but the link on the site is down right now. all i`m doing now is stripping a ford ranger and mounting a fuel injected 5.0 in it for now.
