I was wondering what the best stock 302 HO cam, I know some years are better than others but what is the best one. I am building a dirt track motor and i have to have a stock cam. Im running speed density fuel injection with explorer intake and possibly gt40 heads.

 

kind of up for debate..... probably '93 cobra but if they are what they are advertised... thats my question. i've had too many mustangs that ran so different from year to year with the same mods that i cant be certain
