mpg with LS1 Swap

[HawkZ71]

I was wondering what kind of mileage all of you are getting that did a LS1 swap with a fullsize truck (especially 4WD)?

Thanks

im not sure if it was domeskilla that told me about the mpg issues, but it was all good news

Hay Hauler....did you see a very good increase in mpg after the 5.3-->LS1 swap? and waht gears do you have?
What about you allen? im interested to hear how your mpg is with 4.10's?

I can get about 390miles from my tank which i think is right around 24mpg. I have to drive the speed limit though, which is very hard for me, but i'm very happy with the 4.10's and gas milage. I could go 10-15mph over the speed limit with my 3.42's but those gears didnt' give me near the torque feeling i have with my new setup.

This ls1 gave me a lot more power and a lot more mpg over my 4.3L.
