Might want to start with a couple season in Super Comp or at least a 8.00 or faster car with a five speed.... I would imagine to run the entire pro season and all the national events would kill a million or so.

You would also have to have a comp license, Super Gas would be a good place to start and get your license. I would doubt you could come off the street and climb in a Pro Stock car and be competitive. You're looking at the best 16 shift bangers in the world when you observe a Pro Stock race at a National event. Check out Indy this year, you'll see how many cars can't even make the field.....
