ive run stock and super stock for over 30 years, currently have a super stock car and am about 3/4 of the way to completing another stock eliminator car. the first thing you have to do is decide how fast you want to go, speed cost money, then pick a car and class that will satisfy your needs. unless you want to run a front wheel drive or in the lower classes P Q R T U these can be run at a leeser cost, some with small v/8 engines some with 6 cylinder engines, these combos still take time to get sorted out still takes time and money, im not trying to talk you out of this im just telling you it takes dedication and work, if you can do a lot on your own it much better if you have to pay someone its expensive carb modification cam specs lots of tricks and lots of rules I realy enjoy class racing but not every one does. keep asking questions and listen to the people that are actually racing not arm chair heros. best advice I can give you
