dont use comp cams. they are idiots, you call them up and tell them you want a cam with x specs and they will tell you it cant be done and recomend something terrible. (expecialy if you order up some big LSx cam)
most of the small companies dont grind their own cams, they have comp cams grind them for them. this is the way it is with thunder racing and texas speed, they both just have comp cams grind all their cams. you can get a cam ground directly from comp, but the people you will talk with will be idiots.
