Kurt.
I can get the LS3 at a local salvage yard with complete accessories for cheap but I have procrastinated and been letting it sit there for awhile. I looked at the 5.3l for awhile but I wasn't seeing many benefits of MPG, just a loss of power but I haven't looked into it as much as I should've.

Gerado
15 would be on average is what your expecting? Is that city/hwy and would I be better off to look for a L92 out of a escalade or something, or get a cam for lower end torque in the LS3?
