How would someone get into stock car racing (not drag)

very carefully

Lots of Nascar drivers start by driving Sprint cars on a dirt track and a cheaper prelude to that would be go carts.
Also there are many local tracks with various types of races like hit to pass, Bomber class etc.

Basically, find a local track

Get a copy of heir rules (should be fairly standard, track to track)

Get a car

Comply to above rules

Pay entry fee

Race

Thanx guys I was wondering how these drivers got their starts.

Most of them these days are culled from the cream of the existing crop in the lower divisions.

Most of the bigger cup teams will look at hundreds of drivers each year, planning for a new driver in 5 years. Then slowly invest a little money and time in that driver as he (hopefully) moves up therough the ranks and eventually makes it into a a truck or the busch series.

Your odds are better of getting hit by lightning, but if that'* what you wanna do, go for it. I would.

i would actually love to but right now i'm too involved in the army one and two i'm saving my money and looking for investors to start a business.
