Engine rebuild/ mpg

[bdydrpds10]

I'm about to start to rebuild my motor and wanted to know if anyone has
built one that gets better gas mileage Ex. (17-20mpg) and still had
the HP. Is this realistic on these motors?

gas mileage would have to do with type of tune your are going to go with. i imagine you could but you won't be making the type of horsepower you could be with a truck that is running a little richer.

yes I and many others normally get better than stock milage in high hp trucks, but you have to be realistic, if you drive it making 15psi all the time you are not goin to get 20mpg.
