I for one am going with the 6.4 cam in my 5.7. Two reasons, so I can keep the VVT and because it is significantly cheaper than an aftermarket cam. Might not have the total potential of some of the aftermarket cams, but I’m not looking for 10/10ths. I think 425 or so at the crank should be good enough for now. If not, I can stroke it, or jump to a 6.4 or an HC. :D
