    that truck will probably get worse MPG with 342s then 410s. get him a tune and a fresh tune up and his mpg should raise up

    it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference

    i ve also heard that. i think he has enough power to be alright in city driving.. it is a 345 hp motor,, not like my procharged 5.3l but i thought 3"42's was a good number,,
    what makes you think of worst mileage?
