Thunder valley Marion SD

Hey....want to start getting into drag racing....have no clue where to start.....building a big block stroker to put in Dart or 1/2 ton truck....just curious who to talk to to get started and what I need to do to make the truck legal. Truck is set up with a roll cage.....set back motor....plated 440 mount and so on. Think I am going to start in Marion or Oahe since I am from Eastern South Dakota. Dad raced a Superbird in Marion back in the day.Thanks for the help.

I know a guy around viborg that sells alot of mopar cars and parts, also races a hemi car at marion, send me a message if you want his information, he would be a good guy to talk to.
