What rust free floors look like

Haha,,,,mine isn't going to be anything stellar,,,but for what it is I think it's going to do okay. I'm so used to driving old stuff getting around 15 mpg with most of our cars, that it really doesn't faze me anymore

That's good enough for a daily driver for us.

Dialing in the carb with a wideband has paid big dividends when it comes to mileage on most of our stuff.

My 79 1 ton that you see in one of those pics, is a 454/400 turbo and 3.73 gears and weighs 5,320 lbs. I get 14 mpg out of that thing driving easy.
My fathers newer 03 silverado 3/4 ton with a 6.0 LS motor and 4L80E overdrive gets 14 mpg So much for fuel injection and overdrive technology.
Although I have the advantage of a good tune, those newer trucks from GM have a horrible tune from the factory. I use HPtuner for the newer stuff, and his factory timing table is absolute garbage with large sections of negative numbers With a good tune on that truck I could pick it up another 3-4 mpg easily.
