ok i want to get a 6.0 to swap in my truck and i would like to know what to look for. i know there are the LQ4 and LQ9 but that is all i know. i think that i also read that the 05 and up have LS2 internals. (thats just what i read) so what do i need to look for? more than likely i will go through the engine before i swap.

 

05 and up LQ4's have the LQ9 rods, pistons are still different

 

sweet so one will work? i have seen that the junk yard goes by VIN nuber and i need to know what one i need.

 

The 8th character of the VIN is the engine code.
N = LQ9
U = LQ4
