I had 1500 Ext Cab Silverado prior to my Big Block. When i was looking to get the 2500HD Crew, buddy of mine (who is service manager at GM dealer), said might as well get the Big Block. The 6.0's in HD Crew Cabs were getting about same MPG.
I've been averaging about 10.5 MPG city and 12 highway. I did put 285's on, re-program the CPU and install Volant intake.
My dad had a 1976 K-20HD with 350 v8 and 4 speed...and it got...wait for it...6 miles per gallon. That was city/highway, uphill/downhill, wind-at-back/in-face, full moon/new moon... S I X M I L E S P E R G A L L O N. Dad thought i was crazy to get the Big Block. But it turned out okay in my book.
Wife's Mazda Cx-9 gets 14 mpg, which ain't much better. And that's her daily driver. At least I still have the Accord rocking 30MPG.
