Don't let the name "stock" fool you....most of those stock eliminator cars have more $$$$ in there motor than I have in my entire car. One of my friends has a stock eliminator car (a Demon with a 340), runs almost the exact same ET has my car.....but it is FAR from cheap.
If you want your car to live you will need good parts, good machine work, and a competent builder....remove any piece from that equation and you have a pile of broken parts....JMO. Anything can go fast if you have the knowledge, time, money, and effort.
