Sorry to be negative but if it is a "Copy" from the guy in Plano then it is junk. Alot of members from this site have had their motors trashed because of cams from that guy.
Or you could order one from SDPARTS.com. They had an LS6 cam and LS7 lifter kit for a good price a while back...the lifters alone are like $100+.
