Help Needed - Budget 318 Sprint Car Build

One of the reasons sprint car motors cost so much is that only the best parts are used. The sprint car guys around here ship their motors off to have them refreshed depending on the number of laps they run. At the end of the season they get a full rebuild. If you think about it you might run ok for a few nights but the wear and tear on your motor will probably sideline you when you break something. Also the cost of running a sprint is quite high when you consider fuel(alcohol) and tires. I think it is admirable that you want to do this but the cost is going to be quite high and you have to decide if it fits in your budget.
