V-8 to I6 change

Has anyone ever changed their truck from a 283 or other small block back to a 6? My Suburban originally came with a 292 and PG. I now have a 283 with TH350 but my mileage is suffering big time(5-6mpg) and hard to get any speed up in a short distance(light to light). I don't remember having these issues with the old setup so was thinking of a newer 292 with the TH350. Any ideas on this?
This is my 283- I call it the "gutless wonder"
