LOL, wrong forum, but mine is a mildly built 460 (for towing), to a built c-6, to a pair of Dana 60's, and on out to the BFG 35's. She's a good ole girl with the xlt package (A/C and stuff). Runs strong, but doesn't drive by the fuel stations like the tracker does. 7-8mpg- loaded, towing, empty, freeway, town, etc, just doesn't matter 7-8mpg.
