I didn't have his exact year but on the buick 3800 that would be like driving in 3rd versus 4th and fuel consumption skyrockets above 1500 RPMs from about 40mpg down to about 25mpg 1500-2000rpm
I believe he might be best going to a local transmission place that is willing to work with yah so to say and get a final drive swap done.
I would think a 2.73 would work best, maybe even a 2.5
