Re: K30 15-20 mpg?
If left pretty much stock, a Vortec 454 set up just right might yield 15 on the highway in a K30. If you want it to look "tough" it's gonna cost, one way or the other. A Duramax or Cummins should easily exceed 15, maybe even 20, but you have the initial cost and effort put into the conversion.
