My scout has a 392 block shaved 345 heads new comp lifters, comp cam and new valve springs. It runs really good, I have a DUI dizzy and a holley 670 cfm truck avenger carb. I built this truck from the frame up. 30 spline inner and outer axle arb diffs 427 gears atlas 4 speed t-case line-x the entire inside of body bead lock rims 36 irock swampers hot water shower hydro assist steering hydraboost brakes coolers for everything full cage rock sliders and master craft seats. I've put a lot into this truck hopefully this summer I can finally use it. I also have a Traveler with a 345. I think I was getting between 25-30 mpg depending on how I drive. The scout gets like 8-10 mpg
