So what is the best to run on a street strip motor? The alumium is light and supposed to be as strong as some of the steel? The steel are strong and supposed to be as light as some of the aluminum rockers, Ie comp cams stainless are advertised as being as light as alumium but more strength. I have seen crower stainless rockers for AMC that look light and strong. The harland sharps are supposed to be AMC specific and worth every penny? So I am a bit confused at this point whether I should run a lightened stainless rocker or an aluminum?
