Yeah my 03 Sierra 1500HD Crew Cab has a 6.0 in it, but it's also a lot heavier than these single cab SWB trucks are. I get around 12-13 mpg avg. However I do a lot of in town driving. The best I ever got was 14.5 mpg. That was all highway on a trip to Dallas and back. That was also at about 75 mph too. So they don't get the best mpg, but they aren't bad either. Like I told you that day. It gets the same mpg that my 94 ext cab got with the 350 in it, and this one is a lot bigger and heavier.

I'm with you on the LSX swap. The easy and efficient power that they make is awesome, but dealing with all the sensors and stuff can be a pain. There are a lot of kits out there though, that make it a plug and play setup though.
