There are several different cam profiles for the 5.2L/5.9L roller cams. Most of the truck cams are on 106 to 111 lobe sep and most the the passenger car cams are 114 to 116. We have ground a lot of them lately. We can move the sep a couple of degrees one way or the other and increase the lobe lift to about .320” maybe .340” depending in what core you have
