91 full-size chevy help

ok i have a 91 full size chevy with a small block 350 and a 4 speed automatic.
selling it isnt a option and it gets better as mileage than any of these back woods rednecks say is possible. 25 mpg but i know there is more in it. so far all ive done is open up the exhaust,intake and putt it on a diet
