If you want to run with the v8 sprints, I would recommend helping out with a team first. Make some connections. It's another full time job during the week maintaining them before going to the track. How much you want to spend is how fast do you want to go. It took me 4 years to finally get out. I had some stops along the way because I had no personal back ground in Sprint cars. I help out some teams as I was building my own and they help me out with parts and a whole lot of knowledge. Best of luck with it all!
