lets go dirt track racing
I have decided to see if its feasible to build a mopar dirt oval stock car for next year,so Being im a mopar fan, and knowing the motors are good, i know its worth the effort. the rules are catered toward chevys, and if thats how i have to go, i wont even bother. (mopar or no car)
I need a lot of advice , ideas and input to help me make the decision as to if its worth trying. im not new to stock cars, but mopars are another story seeing as how it is a chevy world. ill post some of the rules that ill need advice for, and ill post a pic of a car from the class ill be running.
In a nutshell, no front fenders, the body is narrowed to the outside of the frame, and the wheels are outside the body. im going to call the track to see what can be done to a unibody and if tortion bars are allowed seeing as how its stock.

D) Firewall mandatory between driver s compartment and fuel cell.
E) Wide style bodies okay. Rear tires must extend at least ½ tread width outside body on each side. Body must remain centered on frame.
