Herb McCandless highly praises this cam..I remember him saying quote " if they aren't beside you at mid track they're not going to catch you" ..That 650 actually performs as well as some roller cams..When it's idling it's a real **** talker too..I've heard them in some of my friends cars and running it along in high gear and you can hear the overlap still at 3,000 rpm's...If I'm not mistaken Herb McCandless designed that cam..
