Why? I'd think a turbo /6 would be a better idea. If you want to go thru all that trouble a 5.2 swap would be better. My 95 dak sport 5.2 5 speed gets better milage than my buddies 94 v6 5 speed and his has 3.55's vs my 3.92's. My truck has 149k on it now still will burn them thru 3rd bang 4th and gets around 22mpg
