Big Block Guys.......Average MPG Questions

I am looking at a truck with a Big Block(K20) and was wondering what you guys that are running them average fuel mileage wise. I always wanted a K20, not to mention it will allow me to have a truck while I do all the body work to my C20 Cummins truck. This truck has had a 454 installed running through a 4 spd.

Also, anyone running an NV4500, NV5600, or 6spd ZF behind a big block?
