Sorry to ask such a newbie question, but I am confused on which 6.0 I should look for. Am I correct that the ly6 has l92 heads but vvt? Also, is this the newest of the 6.0 and what vehicle can I find it in (hoping to find a very low mileage take out)? And last but not least, do any of the 6.0s come mated to the 4l70e other than the LS2? Thanks in advance for any advice on this.
