2000 Yukon Denali 4x4 5.7 vortec back to life

[awil9675]

Looking for some assistance in a wide array of subjects. Im bringing my 2000 Yukon Denali back to life by putting a rebuilt engine and transmission in. Does anybody have any insight into a good lift kit for this unit that's not gonna be to invasive? maybe around 3 in nothing crazy, and then what size tires and rims and would I need wheel spacers?

Second question. Anything I can do to improve fuel mileage on this vehicle?

Thanks y'all for the help

Well, lift kit plus tires and fuel mileage are opposites so if you want to increase mpg... don't lift it.

I would definitely install new injectors and the spider too! Call up your favorite cam supplier and ask for their cam that will improve mileage. Get a tune when its all back together. Clean up the ports on the heads before installing. Use brand new QUALITY (Usually OEM) sensors.

LIfting a truck chassis and installing bigger tires will NOT get you better mileage. Cant have both.
