not that any one knows of... we are all kind of in the dark... all we seem to agree on is that if you showed up and tried to run street stock with a 5k your getting bumped and thats all there is to it... the street stock classes are meant for 'normal' cars not competition stuff right, its supposed to offer a place for the regular guys to compete and not get there butts kicked and end up discouraged from returning to more comps. These classes are designed to help grow the sport, and to be honest with what my car can do with 1k, if i ran a 3k amp id go street stock b just to run with louder cars, or even street a around here just because for the most part the few street A cars in the lower mainland are doing mid 140's...
