Building a Dirt Track Car

With the "open" engine rules, you will need to go w2 heads right from the beginning, and you will need lightweight parts in the bottom end, my gut feeling is that you are underestimating what will be needed to be competitive.This sounds like a very expensive class, and you need to go look at the front running cars for a idea what it will take
This,he's got a clue...((Yes,I know.. Captain Obvious..) It does look expensive,and how much circle track experience,do you actually have? I would start ,with a good chassis,and a simple basic engine combination to learn,unless you have serious experience,pocket book/ or sponsors... Don't forget to find out,what certain racers are charging,for sponsor ship ,on the car.Don't get under changed,you have sweat ,soul,and tears in this investment,after a wreck.Remember,there's a lot of work,for some serious fun....
