Thanks for the info from your personal experience!

I'm pretty dead set on a 5.3L. I know they are getting tougher to find, hence why I'm still looking. With that said, I'd like to optimize one with the 5.3. I know getting a 5.3 is counter intuitive when it comes to wanting good gas mileage but we have owned several vehicles with the 5.3 and can't imagine going with another motor. Plus they typically come with nicer interiors than the standard 4.3L work truck.

The desire for decent fuel economy is a shorter term desire as I travel often right now. In years to come a cammed 5.3 or 6.0 might be in store for this project.
