The quality of the kit is great and legit. The one main thing that urks me is that with the truck norris cam they send stock lifters gen V when LS7 lifter should be used. So I had to spend more money for LS7 lifters and new chromoloy pushrods with shorter length. So 400$ extra on top of the 1800 for the kit. Other than that everything else was good shipping was fast jist wish they gave an option or suggested Ls7 lifters. A website credit would be nice for the extra i had to spend or some kind of gesture
