    when swapped for a 6.0. whats your MPG

    when you swapped out your old motor and put in a 6.0,what was your mpg.
    i have a complete lq4 and i am anticipating the swap.
    due to the fact that the mpg would not be any better than the 5.7 currently in my 1997 swb.
    i have heard stories of guys doing the swap in the camaros and the are getting 20+ mpg. i dont know how true this is,but anyways.

    I get 15+ with my 5000# truck and 408(6.7L). With the right tune you should get 16-18 MPG.
