Another ignorant circle track rule that is supposed to “level” the playing field that does nothing bu drive up costs. Is like the cast iron head/cast iron intake rules. Plain stupid.
Just like Wally Parks and Bill Francis both havin hard-ons for Chevy so they bent, twisted and made up the rules so Chevy could win. Had they not done that, It wouldda been Chrysler, followed by Ford and GM in a distant third.
