mopar performance cam specs change?

oh ok yeah I remember hughes use to make smaller lift cams that still made 400hp+ without going over .500 lift on a 340. I also use to have a formula to calculate the open time of certain lift cams. There really on a proper ground cam and stock heads to ever go above .500 lift. But at any rate I will contact hughes and see if they still do the grinds they use to have on their website
