Uummm.. Thats not exactly true.. I mean yes the 460 is a guzzler for sure but there are lots of ways to make it more efficient. I myself got 15.5 mpg highway and 11-12 city when I had my 460. (regret selling it)
Check this out, FOUR WHEELER Magazine's Project M.P.G.
They finished with 343hp, 684 ft lbs torque , 12.23 city and hwy combined mpg, 13.51 hwy mpg, didnt touch any internals of the engine, And that battleship of a truck is a crew cab dually centurion...
